摘要: 就D-S证据合成规则对于冲突证据合成存在的不足,不少学者基于证据冲突概率再分配思想,提出了相应的修正证据合成规则。针对这些修正合成规则的不足,提出了一种改进的合成规则,该规则在综合考虑证据源可信度和证据支持度的基础上,分析证据集的有效性,合理地实现信息融合。数值实验结果表明,新的合成规则不仅克服了现有规则的不足,而且其结果向合理性方向收敛度好,提高了系统的鲁棒性。

Abstract: According to the insufficiencies existing in D-S evidence theory when they deal with the conflicting evidences, many scholars present modified rules base on reallocation of the basic probability assigned to conflict. A new combination rule is presented to mend the disadvantages of the rules. This rule analyzes the validity of evidences according to the extent of conflict with the use of the reliability of evidential sources and support measure of the evidence, and realizes information fusion rationally. Experiments show that the new combination rule overcomes the insufficiencies, and the outputs are constringent on the aspect of rationality, which enhances robustness of systems effectively.
