This paper deals with the multidimensional analysis of well-being from the theoretical point of views
suggested by Dr. Amartya Sen. Sen’s Functioning Multidimensional Approach is broadly recognized
as one of the most satisfying approaches to well-being. The Capability approach and the Functioning
approach of Sen have found relatively many pragmatic applications mainly for its strong
informational and methodological requirements. An attempt has been made to realize a
multidimensional assessment of Sen’s concept of well-being with the use of the Fuzzy Set theory. The
methodology is applied to the evaluative space of Functionings, with an experimental application to
migrated students studying in Chennai, Tamil Nadu.
