摘要: 证据合成规则在处理冲突证据时产生的失效问题,影响了证据理论的应用。为了有效融合高度冲突的证据,在Murphy 规则、邓勇以及张军方法的基础上提出了一种新的基于证据可信度分级的加权平均证据合成规则,实验表明提出的合成法则可以更高效地解决冲突证据合成问题。

Abstract: The invalidation problem,which occurs when the combination rules are used to deal with highly conflict evidences,has limited its applications.In order to efficiently combine highly conflict evidences,based on other combination rules such as Murphy’s,Deng’and Zhang’,a new weighed averaging approach using evidences’ reliabilities is proposed.The real instance shows this combination rules can combine highly conflicting evidences more satisfactory.

Key words: evidence theory, combination rules, conflict evidence, reliability
