Multi-Criteria Decision Making in a Dual Hesitant Fuzzy Set using VIKOR in Commercial Fishery

Multi-criteria Decision Making (MCDM) which that addresses the problem of making a suitable choice from a set of alternatives which are characterized in terms of their criteria, is a normal human activity. When people make a decision, usually they hesitate to express some of their views about certain given criteria's and very often they avoid those situations by not answering them. Many may have extensive knowledge about all the criteria and few others may not. In this paper the VIKOR method is used to assess most commonly consumed fishes and evaluate the favorable one corresponding to people’s preference, in Cuddalore district with the help of Dual Hesitant Fuzzy Sets and we use a new methodology to handle the problem of uncertainty in the decision making situations with the application of VIKOR (Vise kriterijumska Optimizacija I KOmpromisno Resenje: multicriteria optimization and compromise solution) method in a Dual Hesitant Fuzzy Set (DHFS).
