远程协同故障诊断的决策博弈融合

Decision Fusion of Remote Cooperative Diagnosis Based on Game Theory

多个诊断资源参与的远程协同诊断模式中,多个诊断资源给出的诊断结论经常存在冗余、冲突等现状,而决策融合是解决这些问题的一个必需环节。结合博弈论和信息融合技术,提出了一个决策博弈融合模型和决策博弈融合方法。该方法包括两个阶段:一是以信息熵为支付形式的合作决策博弈方法,二是基于熵权的多属性决策方法。给出了它们的具体算法,并以工程装备故障为例,验证了这两个决策融合算法的有效性。

Decision fusion is a necessary part in remote cooperative fault diagnosis （RCFD） with multiple diagnosis resources, because there often exists redundance or conflict phenomena. A game-theory-based RCFD decision fu- sion model and its method are presented. Two diagnosis decision fusion algorithms are described in detail： one is a specific algorithm for cooperative decision fusion based on information entropy of diagnosis conclusion; the other is a decision arbitration algorithm which is based on multi-attribute decision-making algorithm. Finally, taking concrete transportation equipment as an example, this decision fusion method is studied in application and the application examples prove that it is feasible and effective.
