A comparative analysis for multi-attribute decision making methods: TOPSIS, AHP, VIKOR using intuitionistic fuzzy sets

Intuitionistic fuzzy sets (IFSs) are used in methods of multi-criteria decision making. Some techniques are used in each method to use intuitionistic fuzzy information. Therefore, crisp methods can be changed to use IFSs information. The latter are used in Technique for order performance by similarity to ideal solution (TOPSIS), Analytic Hierarchy Process (AHP) and in VIKOR. We apply These methods in Human Capital Indicators (HCI) [1] and we compare them to distinguish differences between used techniques.
