| 摘 要： | 为解决高度冲突证据的合成问题,提出一种基于模糊集的证据组合方法.对证据集中的所有证据对的冲突权进行计算,构造了冲突权矩阵,并提出了一种根据冲突权大小甄别冲突源的方法.引入模糊集理论,根据证据所引起的冲突权大小定义了证据的模糊可信度.按模糊可信度对证据进行预处理,然后用Dempster法则进行组合.实例表明,该方法能有效处理冲突证据的合成问题,保证了冲突证据合成的合理性和可靠性.

| Abstract: | A combination rule is proposed in order to efficiently combine highly conficting evidences.The conflict weights of every two evidences in evidence set are calculated,and a conflict matrix is composed of the calculated conflict weights.A method for distinguishing the evidences bringing on conflicts is presented according to the conflict matrix.Based on fuzzy theory,the fuzzy credibility degree of evidence is defined and formulated as a function of the conflict weights.Each of evidences is preprocessed accord... |
