Ming Xiao · Shuju caiji yu chuli · 2004
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.
