A GROUP DECISION MAKING MODEL WITH INTUITIONISTIC FUZZY PREFERENCE RELATIONS

In this study a priority weight generation method on the intuitionistic fuzzy preference relations is proposed. The method consists of two linear programming models which are generalized to the case of group decision making with the weight information defined by each DM. In the models, the collective preference relations are obtained by using the intuitionistic fuzzy weighted geometric averaging operator and additive consistency is considered. Finally, a numerical example is give to verify the validity and applicability of the models.
