| 摘 要： | 针对传统的群决策专家客观权重确定的两类主要方法(即基于判断矩阵一致性程度和基于专家排序向量或判断矩阵元素的聚类分析)的缺陷,提出了一种综合考虑两方面因素的改进方法.首先利用聚类分析方法根据各专家的排序向量得到专家类别间的权重,然后根据单个专家的判断矩阵一致性以及排序向量到类核心的距离确定最终权重.文末给出的算例表明该方法是可行、有效的.

| Abstract: | In order to improve the current method of determining the objective weight in group decision,which is based on the expert's consistency and the clustering,this paper puts forward a new method.Experts are classified into different clusters by their collating vectors,and then the weight of a cluster is given according to the numbers of the experts in the cluster.Each expert gets his final weight according to the consistency of his judgment matrix and his collating vectors among the experts in their cluster. |
