multi-criteria group decision making%triangular fuzzy numbers%VIKOR%compromise solution
The VIKOR method is a multi-criteria decision making aid, which employs linear normalization to offer compromise solu-tions and has been successful y applied to various group decision making problems. However, the conventional VIKOR techniques used to integrate group judgments and the information loss arising from defuzzification are problematic and distort final outcomes. An improved integration method, which is optimization-based, is proposed. And it can handle fuzzy criteria values and weights. The precondition for accurately defuzzifying triangular fuzzy num-bers is identified. Several effective defuzzification procedures are proposed to improve the extant VIKOR, and a comprehensive evaluation framework is offered to aid multi-criteria group decision making. Final y, a numerical example is provided to il ustrate the practicability of the proposed method.
