摘　　要：针对专家和属性权重完全未知的区间直觉梯形模糊数的多属性群决策问题,根据定义的区间直觉梯形模糊数的交叉熵求解专家权重,结合灰色关联分析法定义了综合关联系数和综合关联度,依据所有决策方案的综合关联度最大化的思想构建模型得到属性权重公式,并给出基于IITFN-WAA算子的群决策步骤,最后通过实例分析验证决策方法的合理性。focus on the multi-attribute group decision making problem, in which the attribute values are interval-valued intuitionistic trapezoidal fuzzy number and the expert and attribute weights are complete unknown, according to the definition of cross entropy to solve the expert weights, defining comprehensive correlation coefficient and the degree of comprehensive correlation make use of grey correlation, constructing the model on basis of the maximizing the degree of comprehensive correlation, giving the corresponding group decision method of IITFN-WAA operator. Finally, the expediency of the decision making methods are verified by practical example.
