Multi-attribute Group Decision-making Method for Intuitionistic Trapezoidal Fuzzy Number Based on Possibility Degree
With respect to multi-attribute group decision making problem,in which the expert weights and attribute weights are unknown,the attribute values are in the form of intuitionistic trapezoidal fuzzy number,the concept of intuitionistic trapezoidal fuzzy number is introduced,and a new method based on possibility degree is proposed. Based on the similarity between the experts preference and the group mean values,expert weights and attribute weights are calculated respectively,and then the expert weights and attribute weights are combined to get the comprehensive value. The comprehensive value of each scheme is compared in pairs to get the ordering vector of possibility degree matrix,and according to this,the schemes are ranked. Finally,an example is used to verify the effectiveness of the method.
