诊断策略设计方法综述

Review of Diagnostic Strategy Design Methods

诊断策略设计是装备测试性工作的重要组成部分,对提高装备的性能监测和故障诊断能力,减少测试和维修资源需求,降低寿命周期费用等方面具有重要的意义;通过对国内外的研究成果及相关文献进行分析和总结,较为系统地介绍了AND/OR图启发式搜索方法和智能优化算法两大类诊断策略设计方法的原理及分类;对多故障条件、测试多值输出和测试不可靠条件等复杂条件下的诊断策略设计方法的研究现状进行了分析和综述;在此基础上,从三个方面探讨了诊断策略设计的未来研究方向。

Diagnostic strategy design is an important part of testability for equipment,which is of great significance to improve performance monitoring and fault diagnosis ability of equipment,reduce test and maintenance resource requirements,and reduce life cycle cost.By analyzing and summarizing the research results and relevant literature at home and abroad,this paper systematically introduces the principle and classification of two kinds of the diagnostic strategy design methods:AND/OR heuristic search method and intelligent optimization algorithm.The research results of diagnostic strategy design methods under complex conditions such as multiple fault conditions,the multiple valued tests and unreliable test conditions are analyzed and summarized.On this basis,the future research direction of diagnostic strategy design is discussed from the three aspects.
