3 . under the fuzzy preference , study on the aggregation of individual preference , and prove that even when the individual preferences are exact and the social preference is fuzzy , the different definitions we choose and the different results of social choice we can get 对模糊偏好的集结进行的研究,并证明了就是在极强的条件下,即允许个人偏好是非模糊的,而社会偏好是模糊的,随相关定义的选取不同,社会选择的结果也不同。
And then , some common methods of gdm , such as the ahp method , the weighted geometric mean method ( wgmm ) , the borda - kendall method , the minimum variance ( mv ) method , the clustering analytic method , the cook - seiford distance measure , cb measure , the maximum and the minimum expected values , the concordance and discordance indices , etc . , are used to discuss some consensus problems of gdm , including the consistency of the complex judgment matrix in ahp , the consensus methods of the aggregation of individual preferences ; the aggregation of analytic hierarchy process methods based on similarities in decision makers " preferences , a consensus measure on multiple criteria group decision making 接着本文采用了群体决策中常用的一些方法(如: ahp法,加权几何平均法, borda - kendall方法,最小方差法,聚类分析法, cook - seiford距离测度法, c _ b测度法,最大最小期望值法,一致性非一致性指标法等)对群体决策中的几个一致性问题进行了研究,这些问题包括: ahp中复合判断矩阵的一致性,个体偏好序集结的一致化方法,基于决策者偏好相似性的层次分析模型的集结中的一致性问题和多准则群体决策的一致性测度。
