群体决策的偏差度分析

本文引进群体决策的决策个体和决策群体关于两方案的偏差度，以及群体偏差映射的概念．在建立相应的偏差公理的基础上，研究了群体决策偏差分析的基本理论．同时，还给出一个利用偏差度进行群体排序的方法．

The Preference-Deviation Measure Analysis in Group Decision Making

In this paper, the concepts of preference-deviation measures as well as corresponding functionals of individual and grpup respectively, and that of group preference-deviation mapping in group decision making are all introduced. Furthermore, the preference-deviation axiom system is established. And the fundamental theory on preference-deviation measure analysis in group decision making is founded on the basis of the above system. By the way,a group sequencing method is proposed by means of preference- deviation measure.
