针对评价群体成员权重未知且语言评价信息不完全的群组评价问题,提出了一种基于变权的证据推理解决方法.该方法将各评价群体成员的评价意见作为证据,将位置权向量引入到信度初始分配的建立中,定义了冲突度指数的概念作为证据赋权的诱导分量,结合“大多数”模糊量化算子确定权重,并应用Dempster规则进行证据合成.该方法从证据之间提取权重信息,体现了采纳多数人意见的群组评价思想.最后给出了一个应用实例.
Aiming at the group evaluation problem that the weight of group members is unknown and the language evaluation information is not complete, a method of evidence reasoning based on variable weights is proposed. This method takes the evaluation opinions of each evaluation group member as evidence and introduces the vector of position weights In the establishment of the initial distribution of credibility, the concept of conflict degree index is defined as the inducing component of evidence weight, the weight is determined by “most ” fuzzy quantification operator, and the Dempster rule is applied to the evidence synthesis. Between the weight information extraction, embodies the opinion of the majority of groups to adopt the idea of evaluation.Finally, an application example is given.
