基于信息博弈的协同诊断决策

面对装备日益增加的复杂性和对诊断系统能力的高需求,多诊断资源的远程协同诊断成为趋势.针对协同诊断中存在的资源决策冲突问题,引入了博弈理论;介绍了扩展博弈决策模型及其操作流程,通过双支付参数分别讨论了决策中心与诊断资源联盟间的成本博弈、诊断资源间的决策信息熵递减博弈;并运用多属性决策方法进行决策结论的仲裁.以工程装备故障为例,简述了本博弈决策实施过程.

Collaborative diagnosis decision based information game theory

With the increases of the complexity of equipment and the performance requirement of diagnosis systems,the remote collaborative fault diagnosis(RCFD)with multi-diagnosis resources becomes a research and development tend.Game theory is introduced in the collaborative diagnosis to solve the resource decision conflict problem in RCFD.An extended game decision model and its operating process are described;the cost game between decision center and diagnosis resource alliance and the decision information entropy decreasing game between diagnosis resources are discussed respectively through double payoff parameters;different diagnosis conclusions are arbitrated using multi-attributes decision method.Taking an engineering equipment fault diagnosis,the implementation process of the decision game is described.
