Evidence reasoning has good performance in dealing with uncertain information. But in general, Dempster’ s rule is suitable to solve the problem with high belief and low conflict. In this paper, the drawbacks of Dempster’ s rule mentioned above are analyzed firstly. According to the different resource of conflict, two methods are proposed to solve the problem of high conflict. Furthermore, a new concept “conflict rate” is defined and its formula is given out. The robust range of Dempster’ s rule and these two new methods are easily analyzed with the sectional conflict rate and then extended to general discernment frame. As a conclusion, the two methods have better performance in treating with conflict and robustness than Dempster’ s rule and other rules. Key word: Evidence reasoning, conflict rate, artificial intelligence, robustness.
