摘　　要：提出了指标关联且指标值为直觉不确定语言变量的多指标群决策方法.首先给出了关于直觉不确定语言变量的相关概念及直觉不确定语言变量间的距离计算公式,然后,依据各专家针对指标集所给出的直接关系矩阵,运用DEMATEL方法确定各指标权重,并将各专家给出的决策矩阵集结为群体决策矩阵.进一步地,构建正负理想点向量,并计算各方案与正负理想点向量间的加权距离;在此基础上计算各方案的相似系数,并据此对所有方案进行排序.最后,通过一个项目风险应对策略选择的实例分析说明了本文方法的可行性和潜在应用.A method for intuitionistic uncertain linguistic multi-attribute group decision making is proposed in consideration of attribute correlations. First,some basic concepts and terminologies of intuitionistic uncertain linguistic variables are introduced,and the distance formula for intuitionistic uncertain linguistic variables is given. Then,based on the direct relationship matrices of the attribute sets,the weight of each attribute is determined by using DEMATEL method. And the experts＇ decision matrices are aggregated into the group decision matrix. Furthermore, the positive（ negative） ideal point vector is constructed,and the weighted distance between each alternative and the positive（ negative） ideal point vector is calculated based on the proposed distance formula. On this basis,the similarity coefficient of each alternative is calculated. The ranking of alternatives is obtained. Finally,to illustrate the feasibility and potential application of the proposed method,an empirical analysis of selecting the risk response strategy for a project is given.
