摘　　要：对Dempster-Shafer证据理论进行了相关研究,提出了一种消除Dempster-Shafer合成法则悖论的方法。该方法具有一定的通用性,它将专家的焦元一致化,通过对专家给出的原始概率进行修正以达到消除悖论的目的;并通过具体例子说明了这种方法的有效性和可靠性。最后给出了用计算机消除Dempster-Shafer合成法则悖论的仿真算法。This paper gaves a simple introduction of evidence theory and analysed the cause of absurdities. A new method of dispelling the absurdities was presented. This method could dispel the absurdities generated by D-S combination formula by making all experts make their decision on the same focuses collection. The rightness and the efficiency of this method were proved by several examples. Simulation algorithm to dispel the absurdities was given in the end.
