| 摘 要： | 针对现有冲突证据合成方法的缺陷．提出了一种改进冲突证据合成的方法。首先根据候选焦元的冲突大小提出了一种相互支持度．然后由支持度归一化获得候选焦元的相互可信度。最后用该可信度对焦元进行自适应加权组合，实现对融合模型的改进。计算结果表明．改进后的新方法合成效果好．合成结果更理想。

| Abstract: | A new D-S conflict evidence combination method is proposed. Firstly, a rout ual support degree between candidacy focal elements is proposed. Then the credibility of candidacy focal elements is achieved by normalization of the mutual support degree. Finally the fusion model is improved according to the adaptive weighting combination of focal clcments using the credibility level between focal elements. The result indicates that this method has the advantagc of betlot performance and more rational. |
