摘　　要：针对D-S证据理论中Dempster组合规则出现的反直观结果问题,提出了一种新的基于Dempster组合规则适用条件的冲突证据组合方法。首先分析了Dempster组合规则出现悖论的原因及其适用条件;其次发现了基于数据模型修正的冲突证据组合方法不满足结合律的不足,最后依据适用条件对证据模型进行修正并利用Dempster组合规则进行融合,真正满足证据组合的结合律。实验分析表明,所提方法是合理有效的。This paper proposes a new conflicting evidence combination approach based on the applicable condition of Dempster＇s combination rule in order to suppress the counter-intuitive results in using Dempster＇s rule of combination. It first analyzes the reason for the unreasonable results in using Dempster＇s combination rule and presents a new applicable condition of Dempster＇s combination rule. It subsequently indicates the disadvantage that the existing combination method of conflict evidence based on evidential model modification does not satisfy the associative property. Finally the combination rule is used for model modification of the original evidences,and Dempster＇s combination rule is applied to evidence combination,which really satisfies the associative property. Some numerical examples are provided to show the efficiency and rationality of the proposed approach.
