In late August, Hurricane Harvey unleased a devastating assault on Houston, site of the 2017 INFORMS Annual Meeting on Oct. 22-25. For some INFORMS staffers and volunteers, Harvey brought back memor ies of Hurricane Katrina, which wreaked havoc on New Orleans two months before the Crescent City was scheduled to host the 2005 INFORMS Annual Meeting.

Along with sending its thoughts and prayers to those people directly impacted

by Harvey, INFORMS again had to address the obvious question:What to do if Houston is unable to recover sufficiently in time to host the conference?

The INFORMS Annual Meeting is a massive event, drawing more than 5,000 attendees from all over the world. Given its size and the number of meeting rooms and hotel rooms required, there aren’t many cities and convention facilities in the country that can accommodate such a conference. For this reason, the annual meeting is booked years in advance, and even if you could find an alternative site on short notice, rerouting 5,000 people who have purchased plane tickets and booked hotel rooms presents a logistical nightmare, even for an analytics-oriented organization such as INFORMS. INFORMS knows the dr ill. As with Katrina, INFORMS staff led by Executive Director Melissa Moore and volunteer conference chairperson Bill Klimack immediately got in touch with Houston officials, including convention and hotel managers, to monitor and assess the situation. At the same time, they began searching for a possible alternative site, just in case.

In 2005, after Katrina, INFORMS’ then-meetings director Terry Cryan and then-conference chair Jim Cochran quickly found an alternative site, San Francisco, and the meeting moved 2,300 miles across the country seemingly without a hitch, as big and successful as ever.

October 2017

This year, after several tense days of watching and working on possible alternatives, INFORMS received word that downtown Houston had escaped its battle with Harvey relatively unscathed, and the 2017 Annual Meeting would go on as scheduled at the George R. Brown Convention Center, which was home to almost 10,000 refugees immediately following the hurricane.

Ironically, the original theme of this year’s conference was, “Houston, we solve problems,” a riff on the city’s NASA Space Center and the near-tragic Apollo 13 flight that was miraculously saved by engineering ingenuity.

Houston itself had a catastrophic problem with Hurricane Harvey, and by all accounts the city is doing an inspiring job of solving it with local, state and national help. Meanwhile, large areas of Florida and Georgia soon felt the wrath of Hurricane Irma, and Hurricane Maria leveled Puerto Rico and other Caribbean islands. Recovery from such devastation is a long-term problem that demands a coordinated, efficient, universal response.

Now is the time for O.R. folks involved in humanitarian relief logistics and associated disaster health-related issues to rise to the occasion. One such person is Georgia Tech professor Eva Lee, a longtime and often-decorated (Edelman Award winner and threetime finalist) member of INFORMS, whose recent research and application of personalized medicine and postdisaster healthcare issues is the subject of a profile on page 22.

Ironically, Lee worked with Harris County (Houston area) and Puerto Rico in recent years on strategies to contain the Zika virus. Now she’s concerned about another outbreak of Zika in hurricane-ravaged areas, noting that flooding and pollution provide the “perfect breeding conditions” for the virus. ORMS

INFORMS President president@informs.org

A rose by any other name …

In my last President’s Desk article, I referenced the classic Clint Eastwood western, “The Good, The Bad and The Ugly.” This time I chose a more refined title based on a well-known Shakespeare quote, “a rose by any other name would smell as sweet.” I chose this because recently there has been a lot of debate about what terms we use to describe what we do. “Operations research” and “management science” are among the longest standing and most recognized names to people within our field, but they garner little recognition outside our field. Some people advocate for new names such as “analytics” and “data science.” One thing is for certain; few topics are more likely to start an enthusiastic discussion among INFORMS members than to suggest changes to the name of our field.

Rather than fuel the discussion, in this article I focus on what I believe is the root cause, which is a broadening of our field driven by increasing availability of data and the subsequent methodological challenges that have followed this trend.

When I started on the INFORMS Board in 2012 – then as secretary of INFORMS – an effort was underway to define the term “analytics.” From that effort emerged the following definition: “Analytics is the scientific process of transforming data into insights for the purpose of making better decisions.” You may or may not like the exact wording of this definition, but I believe it recognizes some important considerations that are driving a lot of 8 | ORMS Today

When I started on the INFORMS Board in 2012 an effort was underway to define the term “analytics.”

change in our field. Over the last decade, we have seen rapidly increasing opportunities to use “real data” to improve decision-making. I believe there are at least two fundamental reasons for this. The first reason is the increasing availability of data due to advances in data collection, storage, curation, maintenance and access. The second reason is the growing awareness of methodological challenges of using observational data to improve decisions. Both of these are presenting opportunities to extend the frontiers of our field.

The increasing availability of data has led to opportunities to create models in new contexts where data were not readily available before. New devices such as sensors, smartphones and RFID tags have lowered the economic barriers to data collection. At the same time, the abundance of data is creating the need to scale standard methods to work with much larger data sets than ever before.

For example, the challenges of using standard techniques such as regression or clustering in big data contexts have driven innovation in the development of fast decomposition methods that can leverage multiple computers in parallel across distributed computing platforms to solve the optimization problems at the core of these approaches. As another example, when large data sets cannot load into memory, new sequential analysis approaches are needed for optimizing online decision-making. Similarly, the availability of high-dimensional data has

created demand for new optimization methods for variable selection in the training of predictive models.

The methodological challenges of using observational data have not traditionally been a priority in our field.

In scientific contexts, the importance of randomized, controlled trials to mitigate bias is well recognized. However, many new applications in our field use complex models that are parameterized using observational data. Observational data suffer from many problems including missing data, measurement error and many sources of bias that can negatively affect the decisions that are derived from operations research models, degrading the value they provide, or worse, making them cause more harm than good.

These problems are rarely covered in operations research classes on topics such as optimization and stochastic models. In fact, many excellent textbooks on topics like these do not address the challenges of parameterizing models at all. This barrier to using operations research models in practice presents important opportunities for new research at the intersection of statistics and operations research.

The above examples of research opportunities suggest the need for more ormstoday.informs.org

These opportunities include increased demand for educational programs at universities, more job opportunities for future academics and practitioners, and opportunities to increase the impact we have on society. statistics in our field. However, there is an equally strong case to be made for better incorporating operations research methods in statistics. Many statistical techniques rely on optimization, but often heuristics are the norm because of the historical challenge of obtaining optimal solutions. Recent advances in optimization and computing technology

have opened the door to solving these problems to optimality, and in some cases, this is exposing significant errors in the use of commonly accepted heur istics [1]. Another area in which our field is contributing is causal inference. In the context of observational data, methods that match data elements by the similarity in covariates are needed to untangle cause and effect relationships [2].

The above examples are just the tip of the iceberg in recent advances related to data-driven models that are making our field more relevant than ever in many important industr ial and scientific contexts. I believe this is causing a fundamental shift in our

Dating analytics, CAP goes digital and more The analytics behind finding true love online via dating services Looking for love online? You are not alone. Nearly 50 percent of the American public knows someone who has used an online dating site and 5 percent of Americans who are married or in committed relationships today met their significant other online. But with so many different online dating platforms, how can users know which one will best meet their needs? According to a new study in the INFORMS journal Management Science, it all depends on if you are comfortable with rejection. If not, be prepared to pay more.

The study,“Competing by Restricting Choice:The Case of Search Platforms,” explains that most sites, such as Match.com, compete by building the largest user base possible, and provide users with access to unlimited profiles on the platform. Others, such as eHarmony.com, pursue user growth with the same intensity, but allow users to only view and contact a limited number of others on the platform. However, despite the limited choice, eHarmony’s customers are willing to pay an average of 25 percent more than Match’s customers.

The study authors, Hanna Halaburda of the Bank of Canada and New York University, Mikolaj Piskorksi of IMD Business School and PinarYildirim of the University of Pennsylvania, created a stylized model of online, heterosexual dating which found that increasing the number of potential matches has a positive effect due to larger choice, but also a negative effect due to competition between users of the same sex.

Therefore, by offering its members access to a large number of profiles, Match’s users are also more likely to experience rejection, as each of their potential matches will have access to a larger number of options, increasing the competition among members. With access to only a limited number of profiles, eHarmony users are more likely to successfully and more rapidly identify a match with an14 | ORMS Today

other user, who because of limited choice, is less likely to reject them.

Ultimately, for online dating users who can tolerate rejection and aren’t bothered by a potentially longer timeframe to identify a match, Match.com provides much greater choice of options. However, for users who are looking to more quickly identify a potential mutual match, eHarmony limits competition that may result in rejection.

CAP certification goes digital

By Jan paul Miller In previous articles, we noted the benefits of CAP® certification, including market differentiation and networking.

Now INFORMS has announced yet another benefit:The CAP program will be converting to digital certificates as of Oct. 1.

Digital certificates? Yes. INFORMS has contracted with Accredible to host its digital certificate platform. Accredible will help our program issue, manage, track and verify digital certificates and badges.

What does this mean for you? Each certificant will have a unique URL landing page. On this site will reside a facsimile of each certificant’s credential.The site can also hold other certificates issued by INFORMS’s continuing education program.

Is it safe? The site offers bank-level encryption and blockchain verification, meaning it’s impossible for people to fake certificates or badges.

Can the information be shared? Yes, certificate recipients can share their page on LinkedIn, Facebook and Twitter.Your LinkedIn profile will stand out with the CAP logo and a link to your unique URL. Will the site replace the CAP online registry? Yes, the site will verify the authenticity of a CAP’s credentials with a white-labeled directory on the CAP website. Data is displayed and guaranteed that it is always accurate and up-to-date.

Will certificates have the ability to be printed? Yes, you can download high-resolution PDFs for printing.

Re-certificants will also be able to have automatic renewal contingent on their fulfillment of their recertification requirements.

The move to digital badging is one small step to help our credentialed cohort get the good news out about their achievements.

Issues in Education

By Lt. Col. Jesse Pietz, Capt. Drew Ives and Capt. Mark Williams

Air Force Academy’s constantly evolving O.R. program 2017 UPS Prize-winning program, characterized by its “Quick Turn Analysis” course, emphasizes the practical application of operations research.

As a military service academy, the United States Air Force Academy has the unique role of developing future officers for its nation.The Academy’s mission is to “educate, train and inspire men and women to become officers of character motivated to lead the United States Air Force in service to our nation.” In the spirit of this mission, the 2017 UPS George D. Smith Prize-winning program prepares its graduates to effectively leverage operations research that enable rational, quantitatively-based decisions for the betterment of U.S. citizens.The program strives to develop well-prepared practitioners through a focus on real-world applications woven into a deliberate and ever-evolving transdisciplinary curriculum.

The U.S. Air Force, established in 1947 as the youngest military service, was born out of a culture of innovation and reliance on technology to defend the nation better.

Similarly, operations research, as a discipline, was born out of a need to better allocate scarce resources during World War II.As one might expect, operations research has been important to the Air Force since its inception and continues to be in today’s increasingly complex and resource constrained environment. In fact, the U.S. Air Force Academy is one of only a handful of undergraduate institutions to offer a degree in operations research, beginning shortly after the Academy’s founding in 1954.

Like all military service academies, the Air Force Academy has an extremely competitive admissions process and a rigorous four-year program for those accepted. Cadets must balance their time among their demanding academic, athletic and military responsibilities. The Academy’s academic 16 | ORMS Today

program is designed with the institution’s mission as well as the identity and culture of the Air Force in mind.The result is a diverse academic core requiring all cadets to be exposed to the arts and humanities in addition to a focus on science, technology, engineering and mathematics. Every cadet graduates with a Bachelor of Science degree.

More than 50 percent of all cadets, regardless of major, complete an introduction to operations research course. This combination of liberal arts and STEM produces well-rounded graduates capable of thinking critically to solve complex problems.As a result, cadets are some of the most gifted and determined students in the nation. Furthermore, operations research attracts the “best of the best” as it is one of the most technically challenging programs available.

The operations research program is not an independent department. Rather, it is jointly administered by the departments of Computer Science, Economics, Management and Mathematical Sciences.

This intentional design enables it to be interdisciplinary and collaborative in

nature, taking advantage of the expertise of each specialty to create a custom curriculum. A member of the faculty from each of the four departments manages the program and recommends any changes to the steering group, which is composed of the deans of each department and provides consistent and thoughtful strategic oversight. However, it is the makeup of the faculty that is the key to the program’s desire to continuously improve.

More than 30 dedicated civilian and military faculty members implement the program with a focus on teaching; the student-to-faculty ratio at the Academy is a surprisingly low 8:1, ensuring all cadets are able to get the personal attention so essential for enrichment.Approximately one-third of the faculty is doctorate-holding civilians who provide long-term continuity and stability in the program as well as practical research.

One-third of the faculty is senior military officers who hold a doctorate degree and have served multiple operational tours and overseas deployments, providing a strategic view to ensure the program is aligned with future Air Force needs. Finally, one-third of the faculty is junior military officers, who are recent master’s graduates from a variety of leading institutions that invigorates the curriculum by bringing the latest methods and software developments from their coursework as well as current problem applications from operational tours.The program exposes cadets to a breadth of areas including optimization, statistical modeling, computation and stochastic modeling.The curriculum is grounded in real-world operations research, which permeates all courses and culminates in a yearlong capstone project.

The U.S. Air Force Academy was the 2017 recipient of the UPS George D. Smith Prize presented by INFORMS. ormstoday.informs.org

Many courses at the Academy, not exclusively in the operations research program, provide practical projects that are indicative of the work they may do after graduating.

These types of projects not only motivate cadets, but they provide invaluable insight into potential Air Force careers. A prime example of this in the operations research program is the Quick Turn Analysis course.

Quick Turn Analysis began as a special topics course in 2009, developed by Lt. Col. Jeremy Noel, who had recently returned from a deployment. It quickly became a permanent course based on demand from the Air Force analytic community as well as positive feedback from students.This intense course is specifically focused on building the analytical skills needed by operations research analysts who sometimes have only a few tools available to them beyond the Microsoft Office suite, the Visual Basic for Applications (VBA) programming language and Google Earth with the Keyhole Markup Language (KML), yet they must be able to efficiently analyze and synthesize complex data. Significant emphasis is placed on ensuring students are able to professionally and persuasively communicate analysis results and insights to senior decision-makers through a wide variety of data presentation techniques, informative graphics and geospatial representations.

The development and success of Quick Turn Analysis is characteristic of the program as a whole. It is inherently project-based, emphasizing the practical application of operations research. In addition, its evolutionary nature is the result of the unique makeup of the faculty.A senior military officer recognized the need while on an operational tour and designed a course to meet that need while rotating back to the faculty. Furthermore, rotating faculty constantly improve the content and projects based on their experience, ensuring it continues to be relevant.While Quick Turn Analysis provides valuable experience working on projects with limited time, the senior capstone provides the opportunity for cadets to learn research techniques and work on the complete lifecycle of a project.

The culmination of the operations research program is the six-semester hour capstone course during a cadet’s final year.

The capstone enables a team of cadets to work on a project from problem definition and scope through the final delivery to the customer. Customers range from government agencies and non-profit organizations to private businesses from industry.

The UPS George D. Smith Prize, presented

by INFORMS, was created in the spirit of strengthening ties between institutions that graduate operations research practitioners and industry; the operations research program at the Academy won this prestigious award in 2017 in part as a result of its ability to exceed this intent through its yearlong capstone. Cadets not only deliver valid results to their client, but they often present at national conferences and compete for undergraduate research awards.The capstone provides cadets valuable experience to begin their careers, and their success is evident in the client testimonials and repeat customers.

The U.S. Air Force has 650,000 employees with a $140 billion annual budget and a mission set that ranges

from air super ior ity and precision engagement to humanitarian relief and the dignified transfer of those who have made the ultimate sacrifice. The U.S. Air Force Academy is the largest supplier of operations research analysts in the Air Force.

What I wish I had known then Professional lessons learned along the way: We stand on the shoulders of giants, but you cannot get there without a ladder.

By Harrison Schramm and Brian Morgan

18 | ORMS Today

|

October 2017

Background: This article came about from a series of discussions culminating in a one-off lecture with the same title.

After receiving several requests for slides, we decided that it would make more sense to simply write an article.

We are collectively at about the 30-year point in our careers as operations research professionals.We’d like to talk about a few professional lessons learned along the way. These are what we know now that we wish we had known then. Many of us are fortunate to have mentors who provide sage guidance at decision points. Whatever the decision, at least it is an informed one.

In the field of operations research, many of us stand on the shoulders of giants, but you cannot get there without a ladder.

Each subsection below is, in our minds, a rung on that ladder.

Doing Work That Matters We recently had dinner with friends from grad school. As we went around the table catching up about our various clients and projects, it became clear that the level of satisfaction with our careers was measured by the impact that our work ormstoday.informs.org

was having on society. Discussion about the “eaches” of our jobs – salary, time off, environment – were conspicuously absent. It was readily apparent that we were measuring our happiness by how much the problems we work on matter. It was both the dinner party and authors’ firm opinion that there is no shortage of worthy problems, and there is plenty of talent, but the “matchmaking” can be quite difficult.

If you find yourself doing work that is both important and challenging, congratulations! Keep at that as long as you possibly can and be sure to enter professional competitions such as the Edelman or Barchi Prize competitions – as appropriate – when the work is complete.Also, savor that moment, because it is our experience that if you can spend 15 percent of your time in that quadrant you should count yourself blessed.

Work that Doesn’t Matter: Feeding Pigeons No matter how good you are, or how hard you try, you will find yourself occasionally in the “not challenging, not important” quadrant.This is a bad place because it has the possibility of becoming an absorbing state, and one you should leave as quickly as you possibly can. However, because few of us have the flexibility to completely choose our own research, sometimes we are stuck.

We offer two possibilities to get out of that “rut.”

First, work that is not interesting can be made interesting by being a test bed for a new programming language or a technique that we want to try out.This is like Mr. Miyagi in “The Karate Kid” using “wax on, wax off,” turning the mundane task of polishing the car to training for competitive karate.The second possibility is more nuanced: look for a problem that is important using a similar technique to your unimportant problem, and apply what you’ve learned.

You will note we have purposefully not defined “important” or “challenging.” These are of course unique to each individual.There are, to us, at least three “keys” to doing work that matters: 1. an important question, 2. quality data, and 3. a proponent. We examine each in turn as follows: 1. An important question. It turns out that no matter how elegant a statistical model of washing our socks we build, it will never be top-tier work [1].This is because it is a question that nobody cares about. Much like a “difficulty score” in competitive diving, the first, key ingredient to having important work is to work on an important question. It is not always obvious what questions are important; much insight can be gained by asking the following:“What are the units on the answer?”This one question tends to snap the problem into focus.

2. Quality data. Everybody’s data is a mess; your organization is likely no better or worse than any other.

No data set is perfect; everyone has a “thread” that

Figure 1: Your professional life. If you find yourself blessed to be in the top left quadrant (challenging and important) congratulations, stay there as long as you can and be sure to enter in the Edelman Competition. If you find yourself in the lower right corner, which we will all visit from time to time, get out of there fast!

someone could pull. However, having quality data – that the people subject to the decision will respect – is necessary and time should be devoted to it.

3. A proponent. This is perhaps the most important factor, and also the most elusive.A proponent is a human being, usually not an analyst, who has the authority to take the work you have done, turn to the people who run the system under test and say,“Go do what these folks just recommended.”

There is

no shortage of worthy

problems, and there is

Collaborations and Teamwork We cannot think of any worthwhile pursuit that is done totally alone. Even individual endurance sports – like the triathlon – leverage a team of coaches, doctors and support crew.The practice of advanced analytics is the same.There is so much to know about any particular sub-discipline that very few people possess domain-wide knowledge. Furthermore, even if one were a walking O.R. encyclopedia unto themselves, they would still need internal peer review to catch mistakes and avoid the intellectual “echo chamber.”

This is why good teamwork, clear and concise communications, and meeting goals are so valued in colleagues.A good teammate is, well, a good teammate.

plenty of talent, but the “matchmaking” can be

quite difficult.

“All happy families are the same; each unhappy family is unhappy in its own way.”

– Tolstoy, “Anna Karenina” Similarly, all productive collaborations share a characteristic; that is, they are productive. All unsuccessful ones have unique reasons for failure. How should one measure the success of a collaboration?

Successful collaborations are measured by what they accomplish. It simply doesn’t matter how painful the work is, how contentious the arguments among colleagues or how long the hours were [2]. If the partnership yields quality, impactful work, then it was successful, period. Great teammates bring out the best in October 2017

Lessons Learned meeting client demands. Focused reflection and selfstudy help prevent intellectual atrophy.We’ll close this section by directing the readers’ attention to Figure 2.

Do you remember when O.R. felt like piloting your own rocket ship while dressed as Prince Charming? If you never felt this way or cannot imaging feeling this way, you should probably choose a different field. The point is, we all felt like this at one time about our lives, our professions and hopefully the practice of applied mathematics. If that feeling has gone – and it wanes for all of us from time to time – do whatever you can to get it back.

Figure 2: Because we all want to be spacemen dressed up like princes on our very own rocket ships. This is how we all felt at one point; where did that feeling go?

you; what is a good teammate for one person might be an awful one for another.As a final point on teamwork, we recommend that you work with the best people who will have you, which is not the same as the best people.

Why is that?

A good collaboration is one where each member of the team contributes something unique. This is a central theme of the book “High Exposure” [3].

Specifically, the best teams are not necessarily made up of the best individual performers in each area.

Good collaboration is possible between people of vastly different standing, because the more distinguished one becomes, the more “good ideas” they already have, the more they need a supply of fresh ideas to keep them going. Think of musicians who move from recording to producing – the Bee Gees and Dr. Dre both come to mind.At some point in our creative lives, our value moves from having new ideas to being able to get other people’s good ideas “done.”

Focusing on What’s Important Focusing on what’s important is slightly different than doing work that matters, as previously described.

Focusing on what’s important to us means taking some time each day and dedicating it to the state of the practice. The payoff for dedicated study of 30 minutes per day – in any discipline of operations research – is well worth the effort. Our skills are constantly eroding, and keeping them sharp is a part of the very definition of “professional.”

It is easy to “lose one’s way” in the sense that we get focused on the day-to-day of making money and NOTES & REFERENCES 1. Discounting, of course, the possibility that the sock-washing model is a 1-to-1 correspondence with some other problem that we care deeply about.

2. Provided, of course, that no laws were broken!

Synthesis: How to Become Influential We’re now ready to finish our work, so how does one become influential? Start by doing the three things mentioned above: Find important work, be a good teammate and keep focused on what’s important. These are all necessary, but not sufficient. To become influential, one must bring these qualities out in others, both in person and at a distance.

Bringing qualities out in a person means to project these traits, through example and encouragement, in your practice or office among your colleagues and co-workers every day. Bringing out these qualities at a distance means writing. We consider the ability to effectively communicate both for internal use and publication as one of the most important ways to do so.

Conclusion We are left wondering how will these thoughts change in 20 years? What will our future selves write that we don’t know today? We think that it will focus on professional challenges that we did not have to worry about during the majority of our careers to date, such as when to quit a job, how best to get new clients and how to choose which technologies to keep up with.

These are important, they are not enough.

Perhaps success will best be measured by all of us “seasoned” professionals – having climbed the ladder that our generation built and looking young analysts in the eye – by seeing how well the next generation surpassed us.

What’s Your StORy? Eric Stephens, CAP Manager, Population Health Analytics Vanderbilt University Medical Center INFORMS member since 2013 What has been your best INFORMS experience thus far?

I have had several wonderful experiences in my relatively short time as an INFORMS member, but perhaps the best thus far has been the opportunity to work as part of the core team to help develop the Analytics Body of Knowledge (ABOK). I was invited by the certification manager at INFORMS to become a member of this group, and found the experience to be incredibly stimulating and extremely rewardingespecially the two-day working session we had at the beginning of the project. Other great experiences include moderating a panel at the 2015 Healthcare conference in Nashville, working with Zahir Balaporia and many others as part of the Engagement with Organizations committee, and of course playing bass with Zahir, Glenn Wegryn, and other wonderful musicians (collectively referred to as "The Algorythmics") during a reception at the 2016 Annual Meeting!

Why did you become a CAP and how has it helped your career?

I first learned about the CAP program about a year or so after it began, and it just so happened that at the time I discovered it, I was looking for additional credentials that I thought might help my career, so the timing was perfect. I definitely feel that it played a role in my ability to land my job at Vanderbilt, but perhaps the most interesting consequence of obtaining the certification is the number of conversations that have resulted. Upon finding out that I'm a CAP, many people are very interested to learn more about it, which has given me the opportunity to be somewhat of an ambassador for the program (which I'm always happy to be!).

What is the INFORMS journal you read the most? Why? By far my favorite is Interfaces due to its focus on application. Since I also teach, INFORMS Transactions on Education is another go-to of mine, especially for project ideas.

Name three uses of a stapler that has no staples.

Georgia Tech Professor Eva Lee discusses

Personalized medicine How OR/MS is helping a revolutionary improvement in healthcare.

By Douglas A. Samuelson

22 | ORMS Today

|

October 2017

Imagine a way to deliver medical care that takes into account genetics, personal lifestyles, different effects of medications on different people, medication interactions, nutrition and compliance with medical directives. Such a system could radically decrease preventable deaths in the medical system, most of which result from unusual reactions to properly prescribed and administered medications or from interactions of multiple medications [4, 12]. It could also make patients’ lives more pleasant by reducing uncomfortable side effects and guiding them to more effective rehabilitation.

Wouldn’t that be exciting? And wouldn’t it be even more exciting if OR/MS could help make this happen?

Well, it’s actually here. It’s called “personalized medicine,” and several researchers are testing the method and the computer software in clinical settings. One of the analysts in the forefront of this revolution is Eva Lee [2], a university professor and a prominent and often-honored member of INFORMS. Lee won an Edelman Award in 2007, along with Memorial Sloan Kettering Cancer Institute, for her work on better placement, in ormstoday.informs.org

real time, of brachytherapy (embedded radiation sources) seeds to treat prostate cancer. She was a finalist/laureate for another Edelman Award in 2012, with the Centers for Disease Control and Prevention (CDC), for work on public health and emergency preparedness, and in 2015, with Grady Health System and Emory University School of Medicine for transforming the emergency department workflow and patient care. Lee serves on the White House panel that recommends responses to pandemics and other health emergencies. In short, she’s a recognized leader in applying OR/MS to healthcare.

Recently, Lee, a professor in the Stewart School of Industrial and Systems Engineering and director of the Center for Operations Research in Medicine and HealthCare at Georgia Tech, has been working on software to track all aspects of a patient’s data and develop integrated medical recommendations.

She now has preliminary results from several studies applying her software in clinical settings.

Promising Early Results In a study with Columbia University, following 2,000 women with high genetic risk of breast cancer, lifestyle changes greatly reduced the risk. Only 11 of the study subjects actually developed cancer during the 10-year study. “We can find genomic, physiological and behavioral factors that act as triggers,” she says, “and those turn out to make a big difference.

“We include all the biology of the cancer,” she adds. “Knowing how it is triggered, how it spreads and what biochemicals in the body support or resist its spread can provide vital guidance. And the biology is precisely about the individual.”

For instance, in prostate adenoma, the most common form of prostate cancer, “the usual treatment plan is specifically designed for the state of the tumor but assumes the prostate is homogeneous,” she says. “But the tumor is distributed unevenly. We can zoom into key places and avoid the bladder if the tumor is not close to it, concentrating more radiation (or drug) where the cancer cells are.”

Cervical cancers are typically about 35 percent fatal once they spread into surrounding tissue. In a clinical trial using personalized medicine, patients had “excellent outcomes and survival rate,” Lee says, “and we might have 5 percent failure in the longer term.We couldn’t achieve this without the personalized approach” [8, 9].

“Chronic diseases are typically not entirely genetic,” Lee continues. “We’re looking at diabetes.

The problem is that there are multiple comorbidities – obesity, hypertension, heart disease.The numerous types of drugs taken make patients more prone to

adverse reactions to medications. And with diabetes and obesity, we really don’t know what’s in the foods we eat. There are lots of medications and hormones in meat.”

It should also be noted that high fructose corn syrup and artificial sweeteners are present in many foods, not just desserts, with numerous, poorly identified effects.

As far as obesity is concerned, “We’ve identified a gene or two, but we don’t know which came first, the gene or the other factors in the body,” Lee says.

For instance, there are known changes in the composition of the large population of bacteria in the intestine that are essential to digesting food. Foods appear to influence the growth of some strains of these bacteria. At least one virus, Adenovirus 36, is apparently associated with obesity [12]. And then there are behavioral factors.

“I have a colleague who lost 45 pounds just by walking 10 miles a day, with no change of diet,” Lee notes. “It’s sometimes quite easy to produce a big effect by a change of lifestyle.”

Eva Lee

describes mental health as “the

most dangerous diseases we’re facing.”

Infectious Diseases Of course, personalized medicine applies to acute infectious diseases. “We worked with a major pharmaceutical manufacturer on a malaria vaccine,” Lee recounts. “Unfortunately, it was only effective for about 23 percent of the subjects. I wouldn’t say it’s useless, just highly personalized, and we need to know more about the other factors.”

Analyzing genomic information, Lee and her vaccinology colleagues identified which patients would benefit from it and how it would benefit them. The result is very important to world-wide trials set for next year [1, 5]. Now, Lee and her team are trying to design next-generation medications tailored to individuals [11].

“We had better luck advising on containing Zika,” Lee reports. “My team has had pretty good predictions for Puerto Rico on disease trend after sufficient cases were reported. We recommended some containment strategies, and they worked pretty well through the summer. But local public health declared success prematurely. It wasn’t totally contained when they thought it was. We did have a lot of pregnant women getting tested, and those numbers are reliable. It is a serious health burden.”

Just having people paying attention to the threat helped, but, according to Lee, the virus maybe making a comeback around Florida and possibly Houston. “It’s hard to control because of the amount of summer travel,” Lee says.

And that was before hurricanes Harvey, Irma and Maria devastated the Houston area, southern October 2017

Florida, and Puerto Rico and other Caribbean islands, respectively. Refugee movements and relocations to temporary shelter, contamination of water and breakdowns of public services are highly likely to multiply the difficulties.

“The flood and the extreme damp and polluted environment make for the perfect breeding conditions.” Lee says of the virus.“We worked with Harris County (Houston area) since May 2016. They did an excellent job. Now, this is a true challenge as they race to eliminate the mosquitos and puddle of water where the eggs are laid.”

Puerto Rico suffered unprecedented destruction in terms of flooding, sewage and chemical waste in the wake of Hurricane Maria. “It worries me greatly about the level of health issues, short term and long term,” Lee states.

Allergies greatly complicate predictions of response to infection, Lee explains, adding that people have very different capabilities and responses, which makes diagnosis difficult. Is it an allergy? A cold? Flu? Early anthrax symptom? Allergies affect the ability of the immune system to repel infections.

Sensitivities to medication vary widely. Is there a genetic component to reactions to infection? For example, the tendency to have a depressive reaction 24 | ORMS Today

to flu is well known, and it may be because it had survival value during historic flu epidemics [12].

Mental Health Professor Lee describes mental health as “the most dangerous diseases we’re facing,” adding that 20 percent to 30 percent of college students are depressed. “These are educated, capable people,” she says. “Some of them may be able to get medical help and receive prescribed medication to control their mood. There aren’t enough psychiatrists in universities to help them.We don’t call it endemic because of social stigma, and we don’t call it pandemic because we don’t know how to treat it.

“We know depression is highly heritable,” Lee continues. “The mother, in particular, affects the child both genetically and behaviorally. But the strong stigma makes it hard to get people to seek treatment. If kids can get help, they can be helped to feel better. This is why patient privacy is so important; people won’t talk about it, so they don’t get the right treatment.”

Social media appears to aggravate the problem.

“People make comparisons to others and feel disappointed,” Lee observes. “It’s natural for us to be affected by what others say and what they have. It ormstoday.informs.org

is human-nature. It’s like an advertisement.The majority of people, perhaps 70 percent, respond to ads.

Maybe as few as 1 percent are never affected. What makes them resilient? We don’t know. We need to.

This will be very useful to mitigate the social influences on depression.”

Mental illness is also related to terrorism, as many of the attacks are “lone wolf” events, often perpetrated by people who have recently discontinued strong psychotropic medications without anyone monitoring them. Clearly, social media plays a role here, too, as many of the events involve little communication that can be detected by law enforcement. Other contributing factors are stigma and the necessity of having care available quickly for those who need it – and not just for mental illness.

As detailed in Homeland Security Presidential Directive-21, community resilience and individual resilience are important elements of national health security, and, according to Lee, the topic of resilience deserves more coverage in public debate and media commentary about healthcare.

Speaking of resilience, Professor Lee says she and her colleagues have had some successful results with Alzheimer’s, making comparisons of brain physical, chemistry and cognitive tasks performance between

patients and people without the disease. “The content of the information they [patients] process seems to play an important role,” she says [3,7].

The Analytics Component How revolutionary is personalized medicine? “We can’t keep saying we have missing data problems,” Lee says. “Missing data remains a challenge, but we can minimize its effects by tailoring it to the specific problems at hand. Our models make good enough use of whatever data we do have to yield good predictions that indicate good or bad courses of treatment. Now the data problem is that everyone’s measurement is different. People are not homogeneous.”

According to Lee, we’re still learning how to take differences among people into account in assessing which effects of treatment and lifestyle have significant effects on outcomes. “Imputation is no longer all that useful,” she says. “And in electronic medical records, we can’t worry so much about what’s missing, because assessing the quality and completeness of the information we have is all part of the data capture routine.”

That is, the absence of some data can be quite informative, such as blood tests not performed

Personalized Medicine because the patient was unconscious and could not give consent. Unconsciousness is very different than choosing not to comply.

Professor Lee and her team are now testing out their first “personalized” models integrating pharmacokinetics (the way in which medications travel through the body and affect it) and pharmacodynamics (the way the body affects the medications). In medical-speak short form, such models are called “PK-PD” models.

“This model is really powerful in terms of prediction. It connects the individual’s response to the actual dosage of drug taken,” Lee explains. “Testing out behavior and compliance or noncompliance alone is not sufficient; the model tells us so much more. The response (of the body) is actually reflecting and capturing the behavior of how the patient takes his or her drug. The model is forgiving and gives good estimates.”

Using the PK-PD relationship she establishes for each patient, Lee optimizes the treatment plan specifically to the individual.The results, implemented at REFERENCES 1.

Grady Health Systems based in Atlanta, are remarkable.

“Doctors spend less time experimenting with which drug type and dosing should be used,” Lee says.“The method also enables doctors to use higher doses early without great concern about adverse effects, thereby getting better outcomes, shortening the course of treatment and lowering the overall dose of medication.The patients maintain good, healthy blood glucose level.As an extra bonus, the cost and amount of drug used is lower. Cost is not in our equation, but we always use less resource when we optimize.”

She adds that, as far as she and her colleagues know, this was the first successful incorporation of personalized patient data into a mathematical predictive model directing treatment [10]. “This kind of predictive analytics, integrating PK and PD on a patient-by-patient level, has been an aspiration of medical practice for nearly a century,” she stresses.

“But now we’re actually doing it, with real patients, with good results.This is a major breakthrough.”

As their work continues, Lee and her colleagues are eagerly awaiting the response of the medical practice community.

“OR/MS supports this personalized medicine approach because we’re used to taking advantage of whatever data streams we have,” Lee adds.“O.R. is not the same as data science. O.R. people are not used to collecting data. Some of us do, but we don’t just collect data. Collecting data and data management are part of data science, but we do more.We build (mathematical) models from data and reach solutions.We influence decisions, policies, strategies, many layers of impact.The key is to implement O.R. on actual patients in the clinical setting, with the O.R. analysts embedded within the medical care team.”

Conclusion Personalized medicine, using OR/MS models to tailor medical guidance and treatment to highly specific individual characteristics of patients, is a revolutionary improvement in medical and preventive care. Models can now integrate effects of medications, interactions, patients’ behavior, genetics, diet and other factors to develop recommendations for the most effective course of action. There is a tremendous potential benefit here for all of mankind, and a major opportunity for OR/MS analysts who can work closely within medical teams in clinical settings. ORMS Douglas A.

Weathering complexity in agriculture O.R. will be the key to understanding the complex genetics that go into what we eat.

By Dan Dyer

The weather has certainly been on everyone’s mind recently.

When you are in farming, the weather is on your mind all the time.

Farmers don’t take a break from thinking about it, honestly. That’s because a late spring freeze can kill an emerging crop. If that happens, the replanting cost could reach $100,000 on an average-sized farm. Or, an extended mid-summer dry period can rob 20 percent or more from the yield potential for a crop. For a farmer, that loss can easily be the difference between profit and loss for the entire year.

We all know local weather is a complex system, and our best predictive abilities have wide margins of error. In agriculture, the situation is even more challenging. This is because crop performance is the result of the interaction of two complex systems: environment and genetics. Consider for a moment the complexity of modern medicine.The advances that have been made in understanding disease processes, and then being able to manage disease treatment, prevention and health maintenance, is among the great accomplishments of our lifetime. Much of these advances in diagnostics, biology, molecular biology and biochemistry can be leveraged directly into agriculture.

But, in fact, humans are relatively simple.The genetic diversity in the corn crop alone is more than the genetic diversity among all humans. And that is only one of the crops we work with and certainly not the most complex.The real difference is we humans control the environment we live in.We can adapt our behavior.We

put on a coat when it is cold.We have air conditioning when it is too hot. Crops, however, live in the ambient environment. And they have evolved elaborate mechanisms to alter their physiology and biochemistry in response to environmental cues.

We are all familiar with the complexity of the environment. We can understand the engines of weather variation such as ocean currents, interacting air masses, solar flux and reflectivity.

But the interactions among these components are so complex that the system retains a significant degree of chaos, which we can only deal with in probabilities, even within a single day. In agriculture, we are concerned with the pattern of weather throughout the growing season. Extremes in temperature or rainfall – too hot, too cold, too dry, too wet – cause critical fluctuations in crop yields.

Until recently, we thought the nature of genetics was pretty simple: four nucleotides, arranged in each species in a fixed order, grouped into a fixed number of chromosomes. Changes in the sequence happened occasionally – called mutations – that sometimes changed the characteristic of the individual. These were passed along from each parent to their child. Wonderful, predictable, clear and relatively simple. Boy, were we wrong.

There are four nucleotides. Most species have a fixed number of chromosomes, but not all. In a sugarcane field, you can find individuals that vary widely in the number of chromosomes. Genes don’t act on their own.There are genes that control groups

Figure 1: Just how important is the impact of environment on agriculture? Figure 1 shows the corn grain production variation over the last five years in North America. Acreage remained roughly constant – the primary source of variation was weather. The production drop in 2012 was valued at $15 billion. One crop, one region, one year with an impact of $15 billion.

of other genes.There are mutations. But there are also systems that fix them. And, sometimes, those systems cause new mutations. And the genes aren’t all in the same order. In fact, different individuals of the same species don’t always have the same number of genes at all. Some are missing or duplicated or moved to another place on the chromosome, or even a different chromosome. Fascinating and complex.

You can start to imagine the complexity when these two systems, each complex on their own, interact. Until recently, understanding this has been beyond the limits of technology. We didn’t have the necessary data or the computing scale. But now we are entering the age of exploration for agricultural data analytics. The data streams are massive. We have weather data collected at hundreds of locations, with nearly continuous monitoring of temperate, solar flux, wind speed and rainfall. Harvest machines record yields as they progress through the field. We have digital measurements and images from drones and satellites. We produce the molecular genetic fingerprint for hundreds of thousands of new crop varieties every year. It is a data resource that was only a dream a decade ago. And now, we have engaged a wide global community of collaborators to explore novel approaches to deriving the critical insights from this extraordinary data resource. Figure 2 shows a simple example.

Being more accurate in matching the genetics to the environment brings enormous social and economic benefits, even in this simple example of datadriven product placement decisions. But this example October 2017

only touches the surface. Now we are exploring the mechanisms of differential responses at the genetic level, asking such questions as:What are the genes in this soybean variety which enable it to perform better under drought than others? What do those genes do, and how are they controlled?

We all know that different plants flower at different times during the season. Gardeners will recognize that different varieties of the same species also flower at different times.You can arrange a tulip garden, for instance, with varieties that will flower in succession for a long season of blooms. This is actually an important characteristic in agriculture. In most seasons, it gets hotter and drier as the season progresses. Hot, dry weather at flowering can be very detrimental to yield. For vegetable growers, predictable time to flowering is especially important, as they target plantings to specific market periods.

But why do different varieties flower differently?

In most plants, temperature triggers flowering – both the accumulated heat during the growth of the plant, and extreme high or low temperatures. For many plants, day length also triggers flowering. But, different varieties respond differently. One variety may be induced to flowering when the day length is less than 14 hours, but for another it may have to be shorter 30 | ORMS Today

than 13 hours, and for a third, day length may not be a trigger at all.As we begin to understand the molecular biology that controls these responses, we can develop varieties with more stable and predictable flowering, despite environmental variation, and develop varieties better tuned to flower under the most ideal conditions for crop productivity.

Application of operations research and advanced data analytics have already had a profound impact on the efficiency of our breeding and product development programs. Now those same disciplines are being used to build models of how genes and environment interact. This is completely changing the way the crops of the future will be designed and developed, with data-driven insights forming a foundation to feed the future population in an environmentally sustainable way.

Whatâ&#x20AC;&#x2122;s Your StORy? Trilce Encarnacion PhD Candidate in Transportation Engineering, Rensselaer Polytechnic Institute INFORMS member since 2015 What prompted you to enter this field? Why? I have always loved math, and while I was in high school I learned to code, so I naturally enrolled in a systems engineering program. In college, I took a data mining class and I fell in love with the challenge and the amazing and sometimes surprising results that you could discover from almost any data set. Now in a PhD program, I have been able to combine my research to solve transportation problems.

What do you think are the most significant barriers for women/minorities in OR/MS careers? How could they be remedied?

This is such a complex topic, one that I feel very passionate about, but cannot do justice in just one paragraph. Studies exploring the obstacles to female leadership abound, many citing biases from current leaders and higher standards. In my personal experience, I can attest to the effect that a lack of role models can have in forming a young person's idea of what professional life looks like. It took me longer than my peers to realize that I wanted to pursue a PhD, because growing up in the Dominican Republic, there were not many PhDs that I could look up to.

When I was an undergraduate, getting an MS seemed like the highest reasonable degree. I think that my experience can be translated to many women and minorities who do not have access to role models growing up. I think that one way we can improve things is to redouble efforts to engage these groups in middle and high school, and show students all the possibilities that these careers can offer.

What advice do you have for new students entering this field?

The key advice would be to become involved in the professional society/section that best matches your interests, and raise your hand at meetings to volunteer. Attend business meetings at the INFORMS Annual Meeting and get involved. You get to meet amazing people and make a difference.

If we were sitting here a year from now celebrating what a great year it's been for you, what would we be celebrating?

I would have a couple of papers accepted that are currently under review, and I would be preparing to defend my dissertation very soon!

The Winter Simulation Conference turns 50 A personal look at the past, present and future of the venerable conference as WSC prepares to celebrate its 50th anniversary in Las Vegas on Dec. 3-6.

By Michael C. Fu and Thomas J. Schriber 32 | ORMS Today

|

October 2017

The Winter Simulation Conference (WSC) is an annual conference that promotes itself as “the premier international forum for disseminating recent advances in the field of system simulation.”

WSC’s main focus has been on stochastic discrete-event simulation, but continuous (possibly deterministic, driven by differential equations, e.g., system dynamics) and combined discrete-continuous simulation can also be found, and the past decade has seen agent-based simulation take a regular and prominent role.

For the authors, it is by far our favorite professional conference, a meeting we look forward to each year and would not want to miss (with a couple of exotic exceptions for one of us, soon to be revealed). It is held annually in the month of December (hence the “Winter” name, although technically it no longer actually takes place in winter, i.e., after the winter solstice or the official first day of winter; and the very first conference actually took place in mid-November, but more on that shortly), and it has ormstoday.informs.org

the following interesting characteristics, many of which are quite unique to WSC: 1. The composition of attendees is split fairly evenly among academics, practitioners and government (mainly military), giving the meeting a flavor not found in many other conferences. This diversity also is reflected in the papers presented, which are split between methodology and application, as well as between research theory and industry (including government) practice.

2. The location of the meeting rotates in a three-year cycle from the Washington, D.C., area to the South and to the West. Because it is held in December, the north is avoided, even though four of the first five meetings were held in New York City, to which it has never returned since. In fact, the first WSC actually using the “winter” moniker was the last one held in New York. This three-year cycle began in 1981, but like every good tradition was temporarily broken in 2012 to allow for the first international venue in Berlin (where the attendees were treated to a truly winter white blanket), to be encored in 2018 when WSC goes to Sweden (and to Singapore several years after that).

Also, in 2010, the “D.C.” turn was held in Baltimore, ostensibly due to an attempt at cost savings, since D.C. had gotten quite expensive in terms of hotel rates. In any case, the return to the D.C. area allows some of us (and especially those in the federal government/military) to save on travel funds every third year.

3. A refereed proceedings is published every year. Starting in 2000, it became freely available on the WSC website (wintersim.org), and issues are now available all the way back to 1968 (the first meeting that had actual papers), although the proceedings articles prior to 1996 are scanned PDF files and not text searchable. Best paper awards are now given annually by both the INFORMS and ACM simulation specialty subgroups.

Winter Simulation Conference 2017 The Winter Simulation Conference (WSC) has been the premier international forum for disseminating recent advances in the field of systems simulation for 50 years. The longest-running conference devoted to simulation as a discipline, this year’s WSC will be held in Las Vegas at the Red Rock Casino Resort & Spa from Dec. 3-6. The theme for WSC 2017 is “WSC Turns 50: Simulation Everywhere!”

WSC is designed for professionals and academics from all backgrounds and across a broad range of interests. Academic tracks include analysis methodology, modeling methodology, simulation optimization, agent-based simulation and hybrid simulations. Applied uses of simulation include social and behavioral simulation, defense and security, modeling and analysis of semiconductor manufacturing (MASM), healthcare applications, logistics, manufacturing applications, gaming, project management, and environmental and sustainability applications. Additionally, WSC features introductory and advanced tutorials, simulation education, case studies, Ph.D. colloquia, poster sessions, and an extensive group of exhibitors and vendor tutorials. In addition to the normal lineup of great tracks and speakers, WSC 2017 will also have a special history of simulation track.

WSC 2017 is sponsored by ACM/SIGSIM, IISE, INFORMS-SIM and SCS, with Technical Co-Sponsorship from ASA, ASIM, IEEE/ SMC and NIST. Early registration ends Nov. 3. Register now at w w w. wintersim.org. ORMS

Las Vegas will play host to WSC 2017 in December.

WSC Turns 50 4. Three regular tutorial tracks – one at an introductory level, another at an advanced level and a third focusing on specific software (including vendor workshops all day on the Sunday immediately preceding the start of the conference). The first and last are targeted at those new to the field, and thus are ideal both for practitioners wishing to apply the modeling and analysis techniques and software implementations to their real-world problems and for graduate students wishing to do the same in their research. The second track is aimed primarily at more seasoned researchers, including graduate students. Tutorials have been an integral feature of WSC from its early days, and their success led to the adoption of tutorials into the INFORMS Annual Meeting program.

5. A Ph.D. colloquium is held the Sunday afternoon immediately preceding the start of

the conference on Monday. A best paper award also is given here.

6. A popular lunchtime special session called the “Titans of Simulation,” which features nuggets of wisdom from leaders with vast experience in the simulation research community. This year’s two Titans are pioneers of the field who have also experienced all five decades of WSC: Robert G. Sargent, professor emeritus, Syracuse University; and Bernard P. Zeigler, professor emeritus, electrical and computer engineering, University of Arizona.

7. A vendor exhibit area, offering demos of stateof-the-art products, began in 1984.

8. Conference sponsors come from a diverse set of societies: INFORMS Simulation Society, ASA, ACM Special Interest Group on Simulation (ACM/SIGSIM), IEEE Systems, Man and Cybernetics Society (IEEE/SMCS), IISE, NIST,The Society for Modeling and

Reminiscences from the early years What is now called the Winter Simulation Conference was the creation of Julian Reitman, Arnold Ockene and Harold G. Hixson. At the time, 1967, Reitman was a major user of GPSS in the Norden Division of United Aircraft. At IBM, Ockene was responsible for the marketing and support of GPSS. Hixson, an active GPSS user himself, was with the Air Force Logistics Command and was also the System Simulation Project Manager of SHARE (the IBM Scientific Users Group).

As Ockene later stated, “Julian was both a prolific model builder and a demanding advocate for ever more functions in GPSS.” During frequent ReitmanOckene interactions, quoting Ockene further, “the topic of a conference devoted to applications of GPSS arose. We had little doubt that the time was appropriate for such a conference.”

Hixson arranged for SHARE to be a conference sponsor, and he became the general chair.

The two-day conference took place in New York City, with Reitman as program chair and Ockene as publicity chair. There were 401 fullhouse attendees, and others had to be turned away. Thirty-four presentations took place. The conference was a resounding success, both technically and financially, triggering a plan to follow it with a successor in 1968.

The 1968 conference, which also took place in New York City, was named “The Second 34 | ORMS Today

|

October 2017

Conference on Applications of Simulation.” The scope of the conference was expanded to include applications based on any simulation language, not just GPSS, and also to include simulation material other than just applications. Reitman was the general chair, while Ockene served as the program chair. The attendees numbered 857. The stage had been set to continue with annual conferences, which, with a 1975 interruption (see below), have continued to this day.

The “Origins and Early Years” of the WSC span the 1967-74 interval. WSC, or “Winter Simulation Conference,” first became the complete name in 1973. During these early years, the WSC had no bylaws, no formal Board of Directors and no formal long-range planning procedures. The early years came to an end with the 1974 WSC, which, although successful in and of itself, was not then mapped into a 1975 WSC by those expected to do so. This could have been the death knell for the WSCs, but thanks to action taken by Robert G. Sargent, Paul Roth, Harold Joseph Highland and Thomas J. Schriber, a bootstrapped 1976 WSC did take place at the National Bureau of Standards in Maryland. This marked the beginning of what is now called the “Renaissance Period (1975-1982)” of the WSCs, characterized by the formation of bylaws, a Board of Directors, and long-range, multi-year planning procedures.

Welcoming WSC Community The second author attended his first WSC in 1968 and, incredibly, has never missed it since, whereas his younger co-author started attending the WSC two decades later in 1988, and has missed the conference only twice in the nearly three decades since (both times when another competing conference took place on a faraway tropical U.S. island state).

The WSC community is incredibly open and welcoming, ready to incorporate new ideas into research and practice. This year’s general chair is Ernest H. Page, while Gabriel Wainer serves as program chair. The conference theme is “Simulation Everywhere!”

In addition to the main conference keynote and two Titan talks, the conference features two other regular keynotes dedicated to the military and manufacturing areas, this year being given

Vision into the Future Bar r y Nelson, professor, Depar tment of Industrial Engineering & Management Sciences, Northwestern University, will deliver this year’s 50th Anniversary Keynote on Dec. 4. His topic: “WSC 2067:What are the Chances?”

Based on his abstract, Professor Nelson’s remarks will span a full century of WSC, from its founding in 1967 to a prediction for its future 50 years hence, in 2067. Here’s an abstract of his talk: “At the November 1967 ‘Conference on the Applications of Simulation Using GPSS’ it seems unlikely that anyone was wondering if the conference would still be occupying a big hotel in 2017. Conferences persist for many reasons, but

incorporate new ideas into

research and practice.

Apply for this INFORMS competition that provides workplace experience for undergraduate and master’s level students. Teams use O.R. and Analytics to make decisions and solve a real-world business problem.

Finalists will present solutions live to an expert panel at the 2018 INFORMS Conference on Business Analytics and Operations Research in Baltimore, Maryland.

Monetary awards will be granted to all finalist teams, as well as award certificates for each team member and school.

Finalists will also receive a travel stipend and complimentary registration to the Analytics Conference.

WSC Turns 50 “I boldly

a technical conference like WSC has to remain relevant to users, vendors, researchers and consumers (not just hotels) to survive. If our kind of simulation vanished, then so (eventually) would WSC. What is required for simulation to “remain relevant” for the next 50 years?

“Without fear of having to answer for my cr imes in 2067, I boldly speculate on what SHOULD matter for the next 10-20 years, if not the next 50, with a focus on our strength: dealing with uncertainty.”

Although not mentioned in the abstract, Professor Nelson has been a proponent of a new paradigm called “Simulation Analytics” that is sure to be a part of his vision. As anyone who has ever heard Barry give a lecture knows, he’s a great speaker, provocative and able to reach every level of audience expertise.

Omnipresent software provides a costeffective, powerful tool for model building that is only limited by imagination.

By James J. Swain

Simulation takes over: reality is for sissies The idea of simulation is now a part of our culture. For example, the popular “Matrix” movies had it that our perceived reality was actually a simulation, while a recent episode of the British series “Dr. Who” imagined that the world we knew was a simulation being used by an alien race to fully study our planet and to map out its weaknesses for conquest. Plots could incorporate simulation because the viewers were already familiar with the concept. In fact, this seems to have spawned a recurring question on the Quora website about the possibility that we are, in fact, living in a simulation.

Movies are not the only exposure that we have to simulation in popular culture. Surely everyone is familiar with various computer games in which some world is experienced through simulation. The gaming industry is on track to surpass music and movies in monetary value which is further evidence of their importance in media and our shared cultural experience.

October 2017

Clearly, most people are both familiar and comfortable with the notion of simulation, accepting that we can use computer software to make a sufficiently realistic rendering of the world as it is or as it might be (zombies!) to explore, to manipulate or simply to entertain.The boundaries to that world will continue to blur, since VR technology may soon allow us to walk around within a simulated world rather than view it from a stationary game or computer screen. At that point, we may have to provide ourselves with a cue to remind ourselves when we are in reality and when in a simulation.

The products that we survey here are designed for a more mundane but critical purpose – to provide business, industry and government agencies the tools to explore, quantify and optimize systems of all kinds. Whether the application is a factory or a port, data center or hospital, local or worldwide logistics system, or military operations, simulation provides the ability to realistically represent and then experiment with myriad systems. An examination of ormstoday.informs.org

S

the vendor websites provides a wide catalog of applications for these and other applications.

Of course, computer-based simulation is an immense field that spans continuous simulations such as missile flight or fluid flow, the cosmically large or the microscopically small. Our focus in this survey is restricted to the realm of discrete-event simulation models that are particularly suited to the operation of discrete parts, patients, vehicles and such in widely divergent fields as manufacturing, healthcare and other services settings, as well as logistics, transportation or military operations to name a few areas of application.

This survey provides a snapshot of a vital and robust area of simulation analysis software. The vendors document both the growth and sophistication of their tools. Of perhaps greater interest is to examine the case studies and the white papers that many provide, demonstrating how the tools were successfully applied and the benefits that were obtained from the effort.

These materials are available on their respective websites.

The Value of Simulation For over half a century, simulation has grown as a tool because it provides us with a cost-effective and immensely powerful instrument for model building that is only limited by imagination.

Simulation has grown with the capability of computers, programming tools, graphical representation and algorithms to support these areas. It was recognized quite early that computers would be ideal for implementing simulations. Of course, what began as a tool for analysis has morphed into a vehicle for entertainment through gaming, and the explosive (and lucrative) growth in that area has propelled further developments in simulation generally.

Beside the growth in simulation tools, we have witnessed a steady growth in the body of knowledge about simulation and the organization of simulations. Data is more accessible and more readily incorporated into models and increasing the level of detail that can be represented. And, of course, simulation tools incorporate the lessons of the experience in the field.

Meanwhile, enabling technologies, such as random number generation, have steadily improved over the decades. The state of the art in random number generation provides virtually unlimited, high-quality random numbers.

Another reason that simulation is so valuable is that experimentation with the real world is rarely feasible.This is especially true both for the military operations and in aircraft trainers â&#x20AC;&#x201C; you can walk away from both a lost simulated battle and a simulated crash, after all. But even in a real system, there are economic and practical limitations to the amount of experimentation that is tolerable. Plant managers have their quotas and deadlines, for instance.

Most of all, simulation can be applied to systems that have not yet been fielded. Simulation has been successful because it is possible to build simulation models that are sufficiently valid and credible for an analysis to be useful in all of these cases.

One of the primary advantages of simulation is that it is a constructive tool. Simulation models attempt to reproduce the states and trajectories of the actual system, using the procedures that the real system would use.This has many advantages. First, it means that

Simulation models attempt to reproduce the states and trajectories of the actual system, using the procedures that the real system would use. model building is based upon a description of the process that is already available or would be a part of any design. Second, it can be efficient, since many modeling languages have evolved generalized constructs or modules such as servers or workstations that fit many modeling situations, or have evolved specialized instances applicable to particular fields such as manufacturing or healthcare, with specialized logic and animation built in.

Constructive models are certainly easier to understand and to explain.While a queueing formula may provide a prediction of the mean waiting time in a queue, its derivation is opaque to most clients and its application is limited.A simulation model provides a statistical estimate, but in most cases, it is feasible to obtain precise estimates (as well as estimates of the precision). Having a flexible tool that can be applied in a wide variety of modeling scenarios is worth the loss of having an exact solution.

Another critical advantage of constructive models is that they generate the states of the system as they would evolve.This state information can be used to drive the animation and permits detailed analysis, including detailed statistical observations about the system. Of course, the former provides a powerful starting point for both validation and user credence. Providing a visually accurate portrayal of the system in question gives increased confidence in any analysis derived from the model. It also can be used to give snapshots about specific examples of typical or worst-case behavior that can be examined in detail.

Animation also can be useful as a tool to facilitate communication and understanding among team members, who often come from different disciplines and backgrounds. Given the widespread familiarity with simulation games, it is likely that simulation tools cannot afford to be without animation output for any model.

Many of the tools in this survey provide libraries of images that allow the realistic portrayal of equipment, parts or people to make the visualization accurate. Most now provide 3-D animation that can be examined from different viewpoints and at various levels of detail. Here simulation benefits from the great strides made in the gaming industry for representation and perhaps the growth of graphics processors on home computers for gamers.

Improvements in programming increasingly allow models to include increased decision-making within the model. For instance, models can incorporate externally linked software for dynamic scheduling. Likewise, simulations increasingly include the ability to provide customers (and other objects) with decision capabilities or to interact with each other. As an example, for simulations that include pedestrian flow, more realistic routes can be plotted. And in a simulation in which an emergency evacuation is to be studied, being able to portray crowding or panic would be an important part of the model.

S I M U L AT I O N SOFTWARE SURVEY

It has long been appreciated that the constructive approach allows a more detailed analysis of the system statistics. Whereas the queueing formula may be limited to a prediction of the mean, in the simulation model it is possible to observe the variability of the response, not to mention relations among different statistics. This is just the beginning of the possibilities! Increasingly it has been noted that analytics and simulation might be good partners. Simulation can provide detailed data that can now be stored and accessed for insights using the tools of analytics, both within simulation replications and between different scenarios or cases.

Once a valid and credible model has been built, it can be used for experimentation and optimization. In the former case, many of the simulation tools have the capability of generating experimental results automatically. They are sometimes called scenario generators or experiments.That is, the user can specify the parameters values to be run, and the complete set of replications can be performed automatically, with the results available as a group. The results can then be compared graphically and statistically. In most cases, the results can be exported for a more detailed analysis using statistical software.

Once a simulated process has been developed, it is frequently (and naturally) desirable to optimize the process or to seek out the best from among specific options. Optimizers such as OptQuest usually use heuristic approaches (e.g.,Tabu search) that seem to work well where little can be assumed about the simulation responses. Optimization is used when the possible scenarios are too numerous to compare directly, so an algorithm is used to search among the parameter values to obtain improved responses.Various ranking and selection methods can be used when there are a fixed number of alternatives to compare to obtain the best solution.

These algorithms are often sequential in nature, determining the number of replications necessary to make a statistically valid decision, depending on how “best” is defined.

Several products have the ability to perform sensitivity analysis on a model scenario given uncertainty in the model parameters. This can be used to determine the parameters that the responses are most sensitive to.

A final reason for simulation success is that the number of people trained in simulation has steadily increased. Most vendors provide discounted student versions of their software and training materials and books for use in the classroom. All industrial engineering programs include simulation in their curriculum, and simulation also is offered in many business and computer science programs as well. Most vendors also have active training programs for new users, with classes available across the world, and many provide blogs, forums and even product-oriented conferences to share experience and new product developments.

The 2017 Survey This survey is the 11th biennial survey of simulation software for discrete event systems simulation and related products (Swain, 2015 [1]). All product information has been provided by the vendors. Products that run on personal computers to perform discrete-event simulation have been emphasized, since these are the most suitable for usage in management science and operations research. Simulation products whose primary capability is continuous simulation (systems of differential equations observed in physical systems) or training (e.g., aircraft and simulators) are omitted here.

variety of these products continues to grow, reflecting the robustness of the products and the increasing sophistication of the users. The information elicited in the survey from the vendors is intended to provide a general gauge of the product’s capability, special features and usage. This survey includes information about experimental run control (e.g., experimental design and automated scenario run capabilities) and special viewing features, including the ability to produce animations or demonstrations that can run independent of the simulation software itself. A separate directory listing gives contact information for all of the vendors whose products are in the survey.

In Memoriam

Thomas L. Saaty

INFORMS

(1926-2017)

By Arjang Assad and Luis G. Vargas Thomas L. Saaty, Distinguished Professor at the University of Pittsburgh, member of the National Academy of Engineering, and creator of the decision-making mechanisms Analytic Hierarchy Process (AHP) and Analytic Network Process (ANP), passed on Aug. 14. He was 91 and remained a creative and passionate researcher until the end.

Tom was born in Mosul, Iraq, on July 18, 1926. His parents were descendants of Assyrian Christians from northern Iraq.

Tom’s father, David, lived in Rhode Island for many years but returned to his home town of Mosul in the early 1900s. David was a well-known entrepreneur; he opened the country’s first ice-making factory in 1923.

His ambition was to modernize Iraq. David’s marriage to Dola in 1925 produced four children: Tom, John, Ben and Grace. Tom was the first child.

Tom went to Brummana High School in Lebanon, a Quaker school, when he was 15. Upon graduation, he attended the American University of Beirut for two years.

He came to the United States as a youth of 19 to attend Columbia Union College in Takoma Park, Md. He went on to receive an M.S. degree in physics from the Catholic University of America. In 1953, he received a Ph.D. in mathematics from Yale University under the supervision of the functional analyst Einer Hille. Tom’s dissertation was on the Bessel Tricomi equation. He conducted postgraduate studies for a year in Paris, at the Sorbonne, under the direction of the algebraic topologist Henri Cartan.

After graduating from Yale, and, despite efforts by Einer Hille who wanted Tom to stay at Yale to do research, he joined Melpar, Inc. as a scientific analyst studying submarine defense until 1954. He then joined the Operations Evaluation Group (OEG) in Washington D.C. OEG was formed in 1945

as a successor to the World War II Operations Research Group that conducted the Antisubmarine Warfare Operations Research Group (ASWORG) organized by Philip Morse in 1942. At OEG, Tom worked on classified submarine detection problems and the mathematics of radar reconnaissance, a topic of interest due to U.S. aircraft flights (RB48 and U-2) over the Soviet Union. This period also produced Tom’s first papers in Operations Research. The 1954 paper resulted from joint work on parametric programming at project SCOOP with Saul Gass. Tom’s survey of queueing theory appeared in Operations Research in 1957.

In 1958, Tom was appointed scientific liaison officer to the U.S. Embassy in London.

His 1959 book, “Mathematical Methods of Operations Research”, was the result of his international travels and served as the first graduate level text on the subject. In 1959, he was named director of advanced planning in the Office of Naval Research (ONR), a post he held until 1961 when he was appointed as scientific analyst in the Arms Control and Disarmament Agency (ACDA), Department of State. He stayed in ACDA during 1963-1969.

He then left to start his academic career at the University of Pennsylvania. In 1979, Jerry Zoffer, then dean of the business school at the University of Pittsburgh, recruited Tom to the university, where he held a Distinguished University Professor Chair. For the next 38 years, Tom was the most widely known member of the Joseph M. Katz Graduate School of Business, with several affiliated appointments in other academic units of the university. During his long tenure at the Katz school, his fame

After serving a year on the INFORMS Board as president-elect, Krishnan will assume the presidency in 2019.

spread internationally. He traveled widely across the globe, and scholars and students from several countries came to Pittsburgh to work with Tom. Tom was trained in pure mathematics and published several volumes in that area.

He then turned his attention to writing books on subjects of interest to the OR community: “Elements of Queueing Theory with Applications” (1961) where he surveyed the literature; “Nonlinear Mathematics” in two volumes (1964); “Finite Graphs and Networks” (1965) and “Optimization in Integers and Related Extremal Problems” (1970). Tom’s book with George Dantzig, “Compact City” (1973), was part of O.R. lore for many years.

Tom is best known for his theory of the Analytic Hierarchy Process (AHP) and its extension to the Analytic Network Process (ANP). Tom developed AHP based on his work at the U.S. State Department’s Arms Control and Disarmament Agency during the Kennedy and Johnson administrations. AHP is a general methodology to derive ratio scales from pairwise comparisons in a multilevel hierarchical structure. It allows alternatives in complex decision problems to be ranked using an intuitively appealing procedure. It has proven to be remarkably versatile in the range of its possible applications.

The first major application of AHP was reported in Tom’s 1977 paper in Interfaces; it addressed the ranking of infrastructure projects in the Sudan. Tom described the mathematical principles underlying AHP in his book “The Analytic Hierarchy Process: Planning, Priority Setting, Resource Allocation” (1980). He continued to author another two dozen books on the subject.

In 2008, Tom was awarded the INFORMS Impact Prize “for his seminal work on the

More a father than a co-worker On a personal note, I worked with Tom Saaty for more than 40 years, but I consider him more a father than a co-worker, for I knew him longer and spent more time with him than I did with my own father. I met Tom in the fall of 1975 when I came to study under him from Spain. From the beginning, I was considered part of his family. After 40 years spent with him I cannot find words to express the sadness I feel, but I am happy to think that perhaps now he has found the answers he was looking for to the innumerable questions he had about physics, mathematics, science and life in general.

– Luis Vargas

Analytic Hierarchy Process, and for its development and extraordinary impact.”

Tom’s past experience in government and arms control made him passionate about conflict resolution, and in particular, finding a solution for the Israeli-Palestinian Middle East conflict. Starting in 2009, he organized seminars with representatives from both sides to a promising mutually acceptable solution that leveraged the AHP/ANP methodology.

An account of this multi-year project is planned to appear in book form.

Creativity, especially in applications of mathematics, was Tom’s passion. He cultivated it in his own research across a remarkably diverse collection of fields. He also loved teaching the creativity course at the Katz school, challenging students to think outside the box. Students who appreciated this challenge remembered him as a remarkable mentor. His book, “Creative Thinking, Problem Solving and Decision Making” (2001), ties together his main pursuits and interests in this area. Tom also was intrigued in decision-making in the brain. He introduced an extension of his discrete eigenvalue model for AHP to continuous spaces to model cognitive brain activity using this approach. He dedicated most of his time until his death to this problem.

Amazingly curious and creative mind I knew of Tom Saaty’s works for years before I got to know him as a friend. Tom was very kind to me when I came to Pittsburgh; he welcomed me to his home and insisted on showing me the city’s sights and attractions. It was in these meetings that I came to appreciate his amazingly curious and creative mind. If thinking can be described as a passionate activity, Tom exemplified it. His home was an open and inviting workshop to international scholars who sought him out. As a researcher, as a teacher, and as a friend and colleague, he brought honor and prestige to his school and the University of Pittsburgh. I join his many colleagues in missing his prodigious presence at Katz.

October 2017

Tom was elected a fellow of the American Association for the Advancement of Science (AAAS) in 1959 and, in 1970, to the Spanish Royal Academy of Mathematical, Physical and Natural Sciences. His election to the National Academy of Engineering came in 2005. His other awards include the Gold Medal of The International Society on Multiple Criteria Decision Making (2000) and the International Quality Function Deployment Akao Prize from Japan (2007).

At the University of Pittsburgh, Tom received the Chancellor’s Distinguished Research Award, the highest award for research at the university. His cumulative Google Scholar citation count exceeded 97,000 citations.

Tom loved music and humor. He possessed CDs and records of all of Beethoven’s works and, at one point in his life, could identify any work by Beethoven. When he was younger, he realized that he was not good at telling jokes. He decided to improve his abilities as a raconteur of jokes. This led to his compilations of hundreds of jokes into many booklets under a wide variety of pseudonyms.

He took special pleasure in sharing these collections with colleagues, friends and students.

Tom is survived by his wife, Rozann Saaty; his children, Linda, Michael, Emily, John and Daniel; his grandchildren, Tom, Michael, Meghan, Amy, Kara, Monica, Emma, Nina, Max and Fletcher; and his great grandchildren, Lydia, Fiona and Lilly. ORMS Arjang Assad is professor and Henry E. Haller Jr. Dean of the Joseph M. Katz Graduate School of Business and College of Business Administration at the University of Pittsburgh.

He is a current member and past chair of the INFORMS History & Traditions Committee.

Luis G. Vargas is professor of Business Analytics & Operations at Joseph M. Katz Graduate School of Business and College of Business Administration at the University of Pittsburgh. He has co-authored several books and numerous papers with Tom Saaty.

new s People Robert F. Bordley, a longtime member of INFORMS, was named professor of practice (or clinical professor) at the University of Michigan where he is director of the master’s degree in Robert F. Bordley systems engineering.

A Fellow of both INFORMS and the American Statistical Association, Dr. Bordley has been integrating decision analysis, Bayesian statistics and marketing science into the systems engineering curriculum.

As a certified analytics professional, expert systems engineering professional, project management professional and professional statistician, Bordley is also integrating certification training into the curriculum.

Bordley was formerly a program director at the National Science Foundation and a technical fellow at General Motors, where he worked in research, portfolio management, strategic planning, marketing and quality engineering.

Bordley will also continue to support Booz-Allen Hamilton as an advisor, where he has worked for seven years.

MIT professor Richard Larson, a longtime member, past president a n d Fe l l o w o f INFORMS, is profiled in the September/ October 2017 issue of Popular Science Richard Larson for his seminal paper and research on queueing that spans several decades. Widely known in the O.R. community as “Dr. Queue,” Larson recalls in the article “the line that broke him” – an extended and seemingly unfair wait at a popular department store – that

inspired his 1987 paper, “The Psychology of Queueing and Social Justice,” in which he famously “highlighted the importance of fairness and feedback to a person’s waiting experience.”

As the article notes, “It wasn’t the 30-minute wait that bothered (Larson). It was how people who arrived after him had beat him to the exit – and that he had not expected a delay.”

The rest, as they say, is queueing theory history, thanks to Professor Larson’s well-documented research in this area.

James J. Cochran, professor of applied statistics at the University of Alabama and a longtime member of INFORMS, accepted an appointment as associate dean James J. Cochran of research for the Department of Information Systems, Statistics and Management Science within the university’s Culverhouse College of Commerce and Business Administration.

Cochran previously served as interim chair of his academic department before transitioning to his new position, where he will be responsible for developing, implementing and overseeing programs to increase the college’s sponsored and published research productivity.

“I am very excited about this new opportunity and the challenges it will provide,” Cochran said.

An active member of INFORMS, Cochran received the INFORMS Prize for the Teaching of OR/MS Practice, served for five years as editor in chief of INFORMS Transactions on Education, and helped organize the INFORMS Teaching Effectiveness Colloquium series and annual Case Competition. He is also co-founder of Statistics Without Borders. ORMS

DEA SolverPro

DEA SolverPro has been widely used all over the world. In response to numerous customer requests, we have released Version 14 with SBM_Bounded Models.

On top of more than 192 models in 53 clusters, Version 14 added a new model, called SBM_Bounded. The basic Slacksbased Measure (SBM) Models usually report the worst efficiency scores for inefficient DMUs, i.e. the projected point is the farthest one on the associated efficient frontier. The SBM_Bounded Models set bounds to slacks, i.e. we project inefficient DMUs by putting a reduction bound (%) to each input-slack and an expansion bound (%) to each output-slack.

Thus, coupled with the SBM_Max model, the projected point serves to offer more practical and useful improvements (Kaizen).

Industry News Frontline Systems announces nextgen Solver add-in for optimization Frontline Systems, developer of the “classic Solver” add-in that ships with desktop Microsoft Excel, announced a newly enhanced, free Solver add-in that works equally well in desktop Excel 2016, Excel Online and Excel for iPad – and handles the smallest to the largest, most challenging optimization models. Upon release, users can obtain Solver in the Microsoft Office Store. More than 100,000 existing “cloud Solver” users will receive the new version automatically.

“Today Frontline offers tools for the full spectrum of predictive and prescriptive analytics, but we’re still best known for Solver,” says Daniel Fylstra, president of Frontline Systems.“In our third-generation free version for cloud use, we’ve greatly extended Solver’s flexibility and power for everyone.”

Frontline’s “next-gen” Solver, designed for mobile devices and touch screens as well, appears in a “modeless” Task Pane to the right of the spreadsheet, where nearly all user selections are made and messages appear.

AIMMS announces new WebUI features AIMMS announced a number of new WebUI features to improve usability for both App developers and end users and significantly enhance how users interact with AIMMS Apps.The features include: • A new page manager and navigation menu that allows App developers to easily create and manage page trees and generate context-specific navigation menu bars at the top of the screen.

• Wizard support, enabling the App developer to easily create wizards with a sequence of pages and entry and exit procedures. Using wizards, developers can guide end users to complete even the most complex tasks.

• The Scalar widget now allows the end user to view, enter or edit longer text strings, such as descriptions.

• A number of changes that make it easier for App developers to work on projects with a WebUI user interface.

Simio simulation yields insights into retirement savings Retirement Clearinghouse, LLC used Simio simulation software to reveal that widespread adoption of plan-to-plan transfers for small-balance accounts could generate more than $115 billion in new employer-plan savings for the current and next generation of plan participants.

The simulation is the first time discrete-event simulation has been used to model the effects of America’s mobile workforce in the retirement industry. Retirement Clearinghouse used Simio to model the effect of leakage – when employees cash out retirement accounts upon switching jobs – for those retirement accounts containing less than $5,000.

J. Spencer Williams, founder, president and CEO of Retirement Clearinghouse, envisions many other opportunities for Simio simulation to provide a picture of the industry.“We are likely to continue building out the mobile work force model so that eventually we will have a clear picture of the full impact that portability solution will have on the industry,” he says.

The nurseryman’s parable The community pool’s Labor Day party had reassembled the group of neighbors, enjoying one of the last hot days of summer and the leisure to enjoy an occasion such as this. Of course, many of them still worked full time during the summer, so the conversation was not just about vacations – although there were plenty of those stories, too.

Jean, the OR/MS analyst who had explained, in an earlier conversation, the importance of coordination and cooperation, seemed a bit fretful.“What’s the matter?” Bob asked. “Are things going badly in national security these days? Anything we should worry about?”

“Nothing beyond the usual, which is bad enough,” Jean shrugged. “You see the same news stories I do about all the backbiting and infighting in this administration, probably even worse than usual, although what’s usually going on in most administrations is pretty nasty. But these things happen in lots of organizations, public and private. I’m glad football season is back, so maybe we can be reminded of the most important lesson you can learn from football.”

“I didn’t think you were much of a football fan,” said Bob, somewhat surprised.

“I’m not,” Jean affirmed, “but you know just about everyone uses sports metaphors to describe management practices. And it makes sense, because it’s a common language, widely understood, and because in sports you have fairly complete information about what happened and what the results were.

The scores and the stats get posted, everybody gets interviewed, there it all is.

Quite a bit more transparent than, say, defense policy.”

Everyone laughed. “So what’s the big lesson?” Bob inquired.

“Simple,” Jean responded. “On winning teams, people don’t tackle their teammates!”

This brought another laugh from the group. “Sounds obvious,” Jean added, “but you’d be amazed how many organizations don’t seem to get the idea.”

Ed, who was more of a football fan than Jean, agreed, “You do have a good point there. You know who Bill Parcells is, right? He coached two different teams to Super Bowl wins and compiled quite a record. He was and still is widely regarded as one of the most knowledgeable commentators on the game. And at one time, when the teams were drafting players, he said something really interesting in an interview: ‘I’m not looking for the greatest players. I’m looking for the players who will do the most to make my team great.’ Good insight, no?”

The others nodded. “Team-building is an art, and not well taught,” Hugh agreed. “We see that in some of our management think sessions where I work, too, and I can tell you it isn’t easy for everyone to see how important conflict reduction is. Being cohesive is often more effective than being right.

You don’t want everyone to think the same way, but you want the differences to remain civil and have everyone remember we’re trying to cooperate.”

“Good luck,” Ann chimed in. “Instead of all these sports coaches, maybe you and your colleagues need to talk to my nurseryman. He had the real picture.”

This, of course, got the group’s attention. Ann recounted, “He was talking to me about my garden, and why it takes so much work to keep it looking good. He explained, ‘From a distance, a garden seems like the most harmonious place in the world, right?

All the plants just coexisting in peace, reaching toward the sun together, pulling up water and nutrients from the earth. You wonder why people can’t be like that.’ And of course I agreed that that was what I thought, too.”

Ann continued, “He told me, ‘That’s how it seems from a distance. But what you don’t see is that actually, under the surface, very quietly and slowly, those plants are all trying to kill each other! The trees drop leaves that smother the grass and run their roots where they’ll soak up all the water. The grapevines wrap themselves around other plants’ branches and literally strangle them. Some of the flowers attract bugs that eat other plants but not those flowers that attracted them. It’s awful out there! And the only thing you can do about it is decide which plants you want to keep, and whack the ones that are harming the ones you want. Simple – and brutal! So much for harmony!’ How do you like that?”

“That explains some healthcare providers’ meetings I’ve attended,” Jack agreed. “They say they’re all working for the public good, but somehow the new proposal for where to add a clinic often cuts into someone else’s practice. Your nurseryman seems to have the right picture of what’s really going on.”

“And that’s why truly open, unrestricted economic competition has never worked,” Bob noted. “You have to have laws to restrain unfair competition or nearly everyone ends up losing. Even in football, baseball and basketball, where the owners figured out they had to have some mechanism to keep the richest teams from dominating so much that the games became uncompetitive and caused people to lose interest in watching. Something to keep in mind!”

“Too bad we forgot to tell the Russians that when Communism fell,” Jean said dryly. “So they’re repeating what we call the ‘Robber Baron Era’ from the American historical experience in the late 19th century.”

“And so are we,” Ed added, “if we’re not careful. And it doesn’t look as if we’re being careful, now does it?”

“Walt Kelly, the cartoonist, had it right nearly 50 years ago,” Jean chuckled. “We have met the enemy, and he is us!” ORMS Doug Samuelson (samuelsondoug@yahoo. com) is president and chief scientist of InfoLogix, Inc., a small R&D and consulting company in Annandale, Va.

OPTIMIZING POWER TRADING AUCTIONS

A GAMS Application in the Energy Sector The German “Energiewende” (transition of the energy system) aims for a power system on the basis of renewable energy sources (RES).

In 2015, about 30% of the power generation was provided by RES. The RES target for 2025 is a 40–45 % share and 55–60 % are expected in 2035. Large parts of these shares are based on fluctuating wind and solar power. For a successful “Energiewende”, a highly efficient matching of generation and demand will be required.

The Auctioning Markets One important element to achieve that is the organization of ancillary services. Those are fast reacting generators used by the transmission system operators (TSOs) to smooth short-term imbalances. These balancing reserves are procured by the TSOs via auctioning markets. Potential suppliers place related offers and the TSOs select the most cost-efficient combination of bids to cover the requirements. Supported by several TSOs, the 50Hertz Transmission GmbH, TSO of Eastern Germany and part of the Elia group, manages an internet platform to collect bids and execute described auctions of balancing reserves.

The Optimization Solution As a technical solution for a timely and robust calculation of the auction results, the optimization software GAMS was chosen.

The auctions translate to a mixed-integer optimization problem in which each country has a certain reserve demand. Exchanges of reserves are possible with respect to export limits and core shares (maximal total import for a country). A combination of bids is selected so that the demand in all countries is covered with minimal costs. CPLEX is the selected solver applying an extended solution pool so that no possible combination is neglected.

The reserve market is currently characterized by many ongoing changes of market design and regional scope. Thanks to the implemented solution, the incorporation of these changes was easy and straightforward. In total, the organization of the reserve market becomes more and more efficient reducing the electricity costs for all consumers despite the challenges of the “Energiewende”.
