在D-S证据理论中,冲突系数不能很好地描述证据之间的冲突,而且当证据高度冲突时会得到有悖常理的结果.为了解决该问题,提出一种自适应冲突证据检验与合成方法.首先,利用证据向量夹角余弦度量证据之间的相似性程度,并提出冲突证据判据,通过冲突证据检验因子实现证据分类;然后,引入冲突比例因子来决定证据的修正方法,并利用相似度对其进行局部或全局修正;最后,将修正后的证据进行检验与合成.通过应用实例验证了所提出方法的有效性. In the DS evidence theory, the conflict coefficient can not describe the conflict between the evidences well, and when the evidence is highly conflicting, it will get the perverse result. In order to solve the problem, this paper proposes an adaptive conflict evidence test and synthesis method. Firstly, the degree of similarity between cosine metric evidences is exploited by evidence vector, and the evidences of conflict evidences are proposed to classify the evidences by using conflict evidence test factors. Secondly, the conflict scale factor is introduced to determine the correction method and the similarity Finally, the modified proofs are tested and synthesized.The validity of the proposed method is verified by the application examples.
