Trapezoidal Hesitant Fuzzy TOPSIS method in Multi-criteria Group Decision-Making

Author: Irina Khutsishvili
Keywords: Fuzzy TOPSIS approach, linguistic term, multi-criteria group decision-making, trapezoidal hesitant fuzzy set.
Annotation:

The proposed study develops a decision support methodology for multi-criteria group decision-making problem (MCGDM). In the proposed methodology the values of the criteria are given initially in linguistic terms. Then, these assessments are expressed in trapezoidal fuzzy numbers. Decision is made using TOPSIS method. Hence, proposed approach is based on trapezoidal hesitant fuzzy TOPSIS decision-making model.
