Multi Criteria Decision Making Under Fuzzy, Intuitionistic and Interval-Valued Intuitionistic Fuzzy Environment: A Review

Multi Criteria decision making (MCDM) problems can be handled with the help of fuzzy set theory and moreover, this theory has been extended to a new concept called IFS named as Intuitionistic fuzzy set. There has been an increasing demand in the growing research under the fuzzy environment because of numerous applications such as artificial intelligence, medical science, logic programming, medical diagnosis, neural networks and machine learning. We have systematically conducted a review on this topic after a deep analysis of 50 research papers to provide a new framework from all the existing theoretical results, logic and applications.
