| 摘 要： | 冲突证据合成之前,确定证据的冲突程度是必须的。为了更加准确表示证据的冲突程度,提出了一种新的证据距离表示方法。通过改进的最大最小法公式,得到证据距离。通过具体的冲突证据实验,冲突证据得到的证据距离最大,从提出的算法得到的证据距离判断冲突证据,和实际结果一致。新的证据距离可以很好地表示证据间冲突程度,可以进一步处理用于冲突证据合成。

| Abstract: | Before conflictive evidence combination,it is necessary to determin the conflictive degree.In order to more accurately represent the conflictive degree of evidence,one new representation was proposed.Improved maximum and minimum method was used to get the distance of evidences by the proposed formula.Experiments of the adoption of specific conflictive evidences show that the distance of the conflictive evidence the evidence is the largest,the confitive evidence determined by the proposed algorithm is same w... |
