摘　　要：针对证据理论在高冲突环境下的Zadeh悖论问题,提出了一种基于交并集的冲突自适应多证据融合方法。基于冲突矩阵计算证据的可信度,并依据可信度对证据进行折扣;基于证据间的冲突关系对组合规则中交集命题与并集命题的权重进行动态调整;将多元素焦元的信任在单元素焦元中进行再分配。Matlab实验仿真结果表明,与典型改进方法相比,该方法具有较高的收敛速度和区分能力,有效地解决了高冲突环境下的多证据融合问题。According to the problem of Zadeh paradox in the high method based on intersection and union is proposed. The reliability confliction environment, a confliction adaptive combination of evidence is calculated based on the conflict matrix which is used to discount the evidences. The weight of intersection and union in the combination rule is dynamic adjusted based on the confliction of evidences. The trust of multi-element focus elements is redistributed to the single element focus elements. Experi- mental results show that the proposed method has fast fusion efficiency and good distinguishment which can effective dissolve the problem in the high confliction environment.
