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.
