An extension of TOPSIS based on linguistic terms in triangular intuitionistic fuzzy structure

摘要

Chen 24 introduced the extension of TOPSIS in the fuzzystructure, while this article stretches the modern approach of TOPSIS tothe intuitionistic fuzzy framework. Linguistic terms are used in this studyto evaluate the weight of each criterion and the rating of alternatives inthe context of a triangular intuitionistic fuzzy number. A new intuitionistic fuzzy positive ideal solution (IFPIS) and intuitionistic fuzzy negative ideal solution (IFNIS) are proposed in this model of extended TOPSIS. Euclidean distance is introduced between two triangular intuitionistic fuzzy numbers to calculate separation between each alternative to both(IFPIS) and (IFNIS). The proposed model’s mechanism is presented withthe help of an algorithm, and then it is applied to the personal selectionproblem. Finally, a comparative study is given between this model andother TOPSIS techniques.
