| 摘 要： | 针对冲突证据的组合问题,提出了一种新的证据组合方法。利用DICE系数表征证据之间的相似度,并计算各个证据与其余证据的相似度之和,在此基础上获得各个证据的归一化可信度。对所有证据进行可信度加权平均,并对各原始证据进行冲突性判定及修正,最后利用DS规则完成证据组合。算例仿真表明,本算法能有效处理冲突证据的组合问题,得到合理的组合结果。

| Abstract: | A novel combination method was proposed for conflict evidence.DICE index was introduced for calculating the similarity between two bodies of evidence,consequently the summation of similarity between each evidence and others was obtained.The normalized credibility was applied to obtain credibility-averaged evidence,which was used to verify and modify the original evidence,and Dempster-Shafer rule was applied in evidence combination.The numerical experiments show that the combination result of the proposed me... |
