物元故障树(MFT)及其诊断方法

Matter-element Fault Tree(MFT) and Its Diagnosis Method

在可拓学理论的基础上 ,阐述了物元故障树的概念 ,并给出了物元故障树的可拓诊断方法。该方法的提出将重点解决故障树分析中的诊断策略生成、事件的可拓检测问题 ,从而大大提高了传统故障树分析的精度和效果。同时引入了可拓关联函数 ,可以确切的计算出故障发生的程度 ,这为故障树的定性分析和定量分析提供了新的思维方法。由于它以全新的理论为支撑 。

Specific concept of matter element fault tree(MFT) based upon extension theory(extenics) is explicated,and its extension diagnosis method is given.The emphasis of this method is the strategies forming and extension detection of the affairs;thereby,the precision and the effect of fault tree analysis are improved.At the same time,the extension relationship function is introduced precisely.It gives a new method to the qualitative and quantitative analysis of fault tree analysis.Because it based upon the new theory-extenics,so it inheres the characters of both in theory and engineering.
