针对Dempster及其改进证据组合公式的不足,提出一种基于均衡交补分担准则的证据组合新方法.首先分析原始Dempster证据组合方法的优势和劣势,然后利用均衡交补信度分配原则合成新的mass函数,最后数值实例对比实验表明新组合方案不但保持了原始Dempster组合方法的优势,而且弥补了其缺陷.
To solve the drawbacks of Dempster rule and improved rule of combination, a novel evidence combination method based on proportional conjunctive and complementary pooling criterion was presented. Firstly, the advantages and disadvantages of Dempster rule of combination were analyzed. Secondly, a new mass function based on proportional belief criterion of conjunctive and complementary belief was combined. Finally, the results of numerical examples show that the proposed approach of combination can not only maintain the advantages of original Dempster rule of combination, but also make up for its disadvantages.
