摘要
针对 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。该公式同时兼顾了多路冲突性和不冲突性证据 ,冲突性证据按加权平均合成 ,不冲突性证据按与运算合成并反映了相互间交叉融合的程度。改进的合成公式不仅反映了证据协调重合程度 ,保持了证据的聚焦趋向性 ,还能合成高度冲突的证据 ,提供的两个例子证明该合成公式具有很好的实用效果。
D S evidence theory is useful to combine evidence from different evidence sources, but there exists shortcomings in some combination rules such as Dempster rule, Yager rule and other rules. A modified combination rule is presented to deal with consistent or inconsistent evidences obtained from multiple sources. The modified rule reflects the intersection of focal elements and adapts AND operation to combine consistent evidences, and allocates the conflict to vary focus element according to its average supported degree. Experimental results show that the new combination rule is very reliable and rational for all kinds of evidences.
