Abstract: With respect to weapon system selection problem, in which attribute weights are completely unknown and attribute values are expressed with linguistic information, a multi-attribute group decision-making method based on extended VIKOR was proposed. The intuitionistic fuzzy weighted averaging (IFWA) operator was introduced to aggregate all the individual decision-making information in order to obtain the intuitionistic fuzzy decision matrix. The intuitionistic fuzzy entropy method was utilized to obtain the objective weights of evaluation criteria. The alternative weapon systems were ranked according to the basic concept of extended VIKOR method. A case study of air-to-ground guided missile selection problem for UCAV and a sensitivity analysis were given to verify the feasibility and stability of the proposed model. A comparative analysis with intuitionistic fuzzy TOPSIS method shows the superiority of the proposed method.

Key words: weapon selection, extended VIKOR method, intuitionistic fuzzy weighted averaging (IFWA) operator, multi-attribute group decisionmaking, intuitionistic fuzzy entropy
