To address difficult mathematics and technical issues, modellers have turned to multiple criteria decision making (MCDM). Incomplete and ambiguous data presents decision makers with several challenges. In order to solve a wide range of complicated systems, the best modelling method in recent years has been fuzzy set theory combined with MCDM criteria.
Helping the decision maker (DM) choose one option from a limited range of possibilities or to rank those options according to many criteria is what multi-criteria decision-making (MCDM) is all about. The greatest dairy product in Uttarakhand is determined by considering its components in this study report. When selecting a choice from a small set of options with many characteristics, TOPSIS is one of the selection method strategies that might be useful. We are receiving more realistic, tangible, and sensitive outcomes with the use of MCDM approaches. To find the optimal solution to a decision-making issue, the Fuzzy TOPSIS approach is used. Finally, using Fuzzy MCDM we find the best alternative which maximize the resources and enhance the local benefits.
