针对目前复杂电子设备故障分析方法存在的诸多问题,提出了一种基于D-S(Dempster-Shafer)/AHP(Analytic Hierarchy Process)证据理论的信息融合系统框架模型。在该模型中,基于专家分析构成识别框架,利用AHP对专家的证据矩阵进行处理,并在D-S证据理论之中引入最优因子合成方法对测试数据进行融合。应用实例表明:该方案可以提高对故障的识别能力。 Aiming at many problems existing in the current complex electronic equipment failure analysis methods, an information fusion system framework model based on D-S (Dempster-Shafer) / AHP (Evidence Hierarchy Process) theory is proposed. In this model, expert framework is constructed based on expert analysis, expert’s evidence matrix is ​​processed by AHP, and optimal data synthesis method is introduced into D-S evidence theory to fuse the test data. The application example shows that this scheme can improve the ability to identify faults.
