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 對模糊偏好的集結(jié)進行的研究,并證明了就是在極強的條件下,即允許個人偏好是非模糊的,而社會偏好是模糊的,隨相關(guān)定義的選取不同,社會選擇的結(jié)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 接著本文采用了群體決策中常用的一些方法(如: ahp法,加權(quán)幾何平均法, borda - kendall方法,最小方差法,聚類分析法, cook - seiford距離測度法, c _ b測度法,最大最小期望值法,一致性非一致性指標法等)對群體決策中的幾個一致性問題進行了研究,這些問題包括: ahp中復合判斷矩陣的一致性,個體偏好序集結(jié)的一致化方法,基于決策者偏好相似性的層次分析模型的集結(jié)中的一致性問題和多準則群體決策的一致性測度。
