Abstract: For dealing with conflicting evidence,this paper determines the weight of evidence by entropy together with support between evidence. The method considers two sides, ability to identify target and surport from other evidence, to determine the weight of evidence. The paper designs the method to calculate weight of evidence. At last, evidence is fused by the method based on discount rate. Compared to traditional methods,the method in the paper is proved better on convergence efficiency decision risk.

Key words: Conflicting evidence, Entropy, I>-S theory, Data fusion
