摘要

In order to solve the problem of group decision making in which the criteria weight and the weight of decision makers are completely unknown in the intuitive fuzzy environment, a multi-criteria group decision method based on improved intuitionistic fuzzy entropy and information integration operator is proposed. Firstly, using the intuitive fuzzy numbers, language variable method and quantitative index value conversion formula, the initial evaluation criteria for decision makers are normalized. Secondly, an improved intuitive fuzzy entropy is introduced to determine the criteria weight and the weight of decision makers. Thirdly, using the intuitionistic fuzzy weight average operator and the intuitionistic fuzzy ordered weighted average operator, integrate the intuitive fuzzy decision matrix, and the improved score function is used to optimize the ranking of options. The feasibility of this method is proved theoretically, and the effectiveness of the method is verified by an example.
