摘　　要：当证据高度冲突时,使用经典D-S组合规则往往不能得出正确的结果。为此研究人员对证据理论的改进进行了大量的研究,但如何度量证据之间的冲突程度却常常被忽视。针对这一问题,分析了经典冲突系数的不足,结合证据距离和经典冲突系数,提出一种改进的证据冲突表示方法,可更好地度量证据之间的冲突程度。通过算例验证了新方法的有效性。The classical D-S combination rule was not efficient to deal with highly conflicting evidences.To solve this problem,this pap er proposed many modified combinative methods,but how to measure the conflict among evidences was an issue which was not well considered.Firstly,it analyzed the deficiency of the classical conflict coefficient.Then,it introduced a distance function of evidence to measure conflict degree together with classical conflict coefficient.And it presented an improved conflict representation method.It can better measure the conflict degree between evidences.The numerical example shows the efficiency of the proposed method.
