基于证据向量差异度改进的冲突证据融合方法
Improved fusion method of conflict evidence based on evidence vector dissimilarity
摘要
Abstract
Traditional Dempster-Shafer theory (DST) involves counter-intuitive behaviors when combining conflict evidence. This paper proposed a new evidence weight and fusion method. It introduced evidence vector dissimilarity to modify the DST conflict coefficient based on the disadvantage analysis of DST conflict definition. Then computed new evidence set mutual support matrix and evidence weight vector using the modified DST conflict coefficient. Finally, combined all weighted evidences with DST combination rule. A numerical example demonstrates the rationality and efficiency of the proposed method in combining conflict evidence. Compared with other improved combination methods,the proposed method is robust and more efficient.关键词
