Abstract:

Evidence reasoning has good performance in dealing w ith uncertain information in intelligent decision making systems. But, Dempster's rule is unsuitable to solve the combination with high conflict. In this paper, the authors firstly review many improved combination rules and analyze the reasons of drawbacks of Dempster's rule mentioned above. In addition, a new kind of method is proposed to solve the problem of high conflict. Two concrete algorithms are introduced with consideration of with a prior and without any prior. As a result, the new methods have better performance in dealing with conflict than other rules.
