| 摘 要： | 对于有冲突的证据,D-S证据理论无法使用或得出错误的结果,解决该问题的基础首先是研究证据冲突的衡量方法.分析了D-S证据理论在合成冲突证据时遇到的问题,定义了一些衡量证据间冲突程度的参数,包括证据一致度、证据冲突度、证据冲突强度、证据冲突/一致度等.通过实例证实了这些参数能够较好地说明证据间存在冲突的程度.

| Abstract: | With conflict of evidences, Dempster-Shafer(D-S) evidence theory either cannot be used or will work out false results. The basis of solving the problems is to study the measure of conflicting evidences. The problems of conflicting evidence combination with D-S evidence theory are analyzed. Some parameters to measure the extent of conflict of evidences are defined, such as evidence consistent degree, evidence conflict degree, evidence conflict intensity and evidence consistent/inconsistent intensity. Effectiveness of the parameters is shown with some examples, which have proved that these parameters can show the extent of conflict of evidences. |
