摘要
针对多属性综合评价问题,提出了一种主客体协作式群组评价方法。首先介绍了评价客体意见的获取手段,给出了一种在评价客体没有能力提供自身意见的情况下的意见提取方法;然后以评价主体提供的信息检验评价客体提供信息的失真程度,以评价客体提供的信息检验评价主体提供信息并判定评价主体的能力大小,据此给出评价客体和评价主体的话语权重;根据"差异驱动"原理,集成评价客体群体给出的评价结果和评价主体群体给出的评价结果,得到最终的评价结论。最后,用一个算例检验了方法的有效性。
To solve the comprehensive evaluation problems, an approach based on the collaboration between the evaluated objects and evaluators is proposed. Firstly, the method of obtaining the evaluated objects＇ opinion is introduced. Secondly, the distortion degree of the evaluated objects＇ judgment can be got based on the evaluators＇ judgment, and the evaluators＇ ability can be judged based on the evaluated objects＇ evaluation judgment. At the same time, each evaluated objects and evaluators weight in the group of their own type can be obtained. Accord- ing to the differentiation principle, the overall evaluation value can be calculated by aggregating the evaluated ob- jects＇ opinion and the evaluators＇ opinion. Finally, a numerical example is investigated to illustrate the effectiveness of the proposed method.
