摘要
针对高冲突证据的合成问题,分析了D-S证据理论及改进方法的不足,提出了一种新的基于修正数据源思想的变权证据合成方法.该方法同时考虑了证据内焦元基本可信度分配值和各证据与平均证据的加权欧几里德距离.实验结果表明,该方法能有效消除证据冲突悖论,在证据一致和高度冲突的情况下均表现出良好的适应性,具有较快的收敛速度和高可靠性.
A new variable weighted evidence combination approach on correction data source thought, which considered basic probability assignment value of focus and the weighted Euclidean distance between each evidence and average evidence, was proposed to overcome it. Experimental result indicates this method can effectively eliminates the conflict paradox of evidence, in the case of evidence of consistent and high degree of conflict showed good adaptability, and has fast convergence rate and high reliability.
