Abstract: In view of the problem that the interactions among expert's preferences and the interconnected effect of indicators was seldom considered simultaneously in the existing logistics supplier decision model,a decision making method for supplier selection based on maximum entropy optimization model and Choquet integral were put forward.By using transition function,mixing evaluation matrices were transformed into interval-valued intuitionistic fuzzy matrices.By introducing the maximum entropy model based on grey relational factor,interval-valued intuitionistic fuzzy matrix was transformed into score function matrix to ensure various performance evaluation indexes from expert evaluation.A methodology of logistics supplier'performance evaluation index based on Choquet integral norm in 2-additive-fuzzy measure space with the expert profile was presented.By using interval-valued intuitionistic fuzzy weighted arithmetic aggregation operator,the comprehensive evaluation values of each logistics supplier and the optimal logistics supplier were selected according to the order relation criterion.A calculation example was provided to illustrate the rationality and validity of the proposed method.
