摘要

本文讨论了Dempster公式、Yager公式和其他几种证据合成公式存在的不足

提出了一种改进的证据合成公式.该公式可合成多路冲突性和不冲突性证据

冲突性证据按加权平均合成

不冲突性证据按按与运算合成并反映了相互间交叉融合程度.实验表明该公式能合成多种包括高度冲突的证据

具有很好的实用性.

Abstract

This paper discusses the shortcomings of Dempster's rule

Yager's rule and other rules

and then presents a modified combination rule to deal with consistence or inconsistence evidences obtained from multiple sources.The modified rule adapts AND-operation to combine consistent evidences and reflects the intersection of focal elements

and allocates the conflict probability to very inconsistence focus element according to its average supported degree.Experiments show that the new combination rule is very reliable and rational for all kinds of evidences including highly conflicting evidences.
