摘要： 针对证据合成法则在证据高度冲突情况下常得出有悖常理的结论，通过理论分析、对比多种改进的合成方法，提出一种基于局部冲突分配策略的组合规则，采用以冲突焦元在局部冲突组合证据中所占的实际比值为权重的方法，将冲突在产生冲突焦元中分解。实验结果证明，即使在证据高度冲突的情况下，改进后的合成法则依然能够取得理想的合成结果。

Abstract: Evidence theory produces counter-intuitive conclusion when the high conflict information exists. On the basis of analyzing and comparing a few improved combination rules, this paper presents a new combination rule based on partial conflict allocation strategies. It considers actual ratio of evidence as weight coefficient and redistributes the partial conflict into focal element which invokes conflict. Experimental results show that even in the case of high degree of evidence conflict, the new combination rule still can achieve the ideal synthesis result.
