Abstract

Abstract: In order to solve the problem of group decision-making where the expert evaluation information is mixed with multiple attributes and the weights are unknown, a method for determining the weights of expert attributes based on the dissociation of attribute values and fuzzy entropy of each scheme is proposed firstly, and then the dynamic combination weights of different experts are obtained through linear weighting, and a new multi-attribute group decision-making method based on trapezoidal fuzzy number is proposed after combining them with Boolean values. Finally, the rationality and feasibility of this method are verifed by the actual case analysis.

Key words: trapezoidal fuzzy number, separation degree, fuzzy entropy, dynamic combination weight, Boolean values, group decision-making
