基于差异驱动的主客体协作式综合评价方法

Collaborative Comprehensive Evaluation Approach Based on Differentiation Principle

针对多属性综合评价问题,提出了一种基于差异驱动的主客体协作式综合评价方法。在主客体协作式综合评价过程中,首先获取被评价对象(评价客体)和外部评价者(评价主体)的属性赋权向量;然后以评价主体和评价客体落在意见一致区间内的成员个数占本群体成员的比例判断该群体应采取怎样的赋权策略,并据此给出评价主体和评价客体的话语权重;根据"差异驱动"原理,综合集成来自主客体的评价信息,得到最终评价结论。最后,用一个应用例检验了方法的有效性。

To solve the problems of comprehensive evaluation, we suggest an approach of collaborative comprehensive evaluation based on differentiation principle. In the process of collaborative comprehensive evaluation, we must get every evaluation agent＇s judgments firstly. Then we can obtain the numbers of the evaluated objects and the evaluators who are in the consensus interval. So we can judge which weight determining strategies would be selected and get every evaluation agent＇s weight in the group of their own type afterwards. The conclusion of comprehensive evaluation is got by aggregating the evaluating result of all the objects according to the differentiation principle. Finally, a numerical example is given to illustrate the effectiveness of the proposed method.
