针对Dempster方法在合成高冲突证据时存在的问题，分析了现有改进方法的缺点，提出了一种新的改进方法。该方法首先利用证据之间的相似系数求出各证据的初级权重；然后引入权重折扣因子，将冲突证据的权重按折扣因子折算后并入到其他证据的权重中，得到各证据的综合权重；最后对证据加权平均后再利用D-S组合规则进行组合，通过算例比较表明改进后的方法合成结果更加有效。
針對Dempster方法在閤成高遲突證據時存在的問題，分析瞭現有改進方法的缺點，提齣瞭一種新的改進方法。該方法首先利用證據之間的相似繫數求齣各證據的初級權重；然後引入權重摺釦因子，將遲突證據的權重按摺釦因子摺算後併入到其他證據的權重中，得到各證據的綜閤權重；最後對證據加權平均後再利用D-S組閤規則進行組閤，通過算例比較錶明改進後的方法閤成結果更加有效。

To deal with the problem arising in using D-S combination rule for the combination of highly conflicting evidences,disadvantage of existing improved method have been analysed. So a new modified method is proposed,the new method has first calculated the evidence primary weight via similarity degree of evidence. Then the concept of the evidence weight discount coefficient is introduced,weight of conflict evidence times discount coefficient is calculated and the evidence weight to form an overall weight of evidence is marged into. Finally,D-S combination rules is used to combined the weighted average evidence. An example indicates that the new method can give the more reasonable combination results compared with D-S combination rule and the other modified methods.
