But the traditional combination rules are mainly under fixed discernment frame(Shafer model and free DSm model) responding to static model. A new method for dynamic proportional conflict redistribution rules(dynamic PCR rules) based on hybrid DSm model is proposed for the shortness of classical dynamic PCR rules. In the new dynamic PCR rule, combination involved with empty set is defined as one kind to obtain more reasonable results. For the redistribution weight, the conjunction Basic belief assignment(BBA) and conflict redistribution BBA are both taken into account to raise the fusion precision.The effectiveness of revised dynamic PCR rule is studied and simulated in both aspect of fusion accuracy and calculation. 关 键 词：联合规则 PCR 熔化 框架 Basic DSM 再分配 模型
