Abstract: To deal with multi-attribute group decision making problems with multi-granularity linguistic phrases of attribute values and attribute weights, a method based on subjective-objective attribute weights integrated and extended Vlsekriterijumska Optimizacija I Kompromisno Resenje （VIKOR） is proposed. The multi-granularity evaluation matrices are unified into the same granularity by the basic linguistic term set, The group evaluate deviations to every attributes are calculated according to the translated linguistic decision matrixes, then the objective weights are obtained by the consistency principle of group evaluation opinions, subjective weights of every attributes are calculated by using the Two-tuple Weighted Averaging （T-WAA） operator, thus, subjective weights and objective weights of attributes are concentrated into comprehensive weights. Evaluation matrixes given by all decision makers are aggregated into group evaluation matrix and its export matrix. Based on extended VIKOR method, the compromise rank result of alternatives is obtained from the group utility values, individual regret values and comprehensive evaluation values. An illustrative example analysis shows the effectiveness and feasibility of this method.
