基于Chwa&Hakimi故障模型的集团诊断

Node grouping diagnosis based on chwa&Hakimi fault model

提出了基于Chwa＆Hakimi故障模型的集团诊断,定义了绝对故障集和最终诊断图,由此能找到所有的基于Chwa＆Hakimi故障模型的相容故障模式。从仿真结果看大大减少了系统级故障诊断的复杂度,特别是对强t-可诊断系统,具有较大的实际意义。

This article arises node grouping diagnosis based on Chwa&Hakimi fault model and defines absolute fault sets and finally diagnosis chart, on which all the consistent fault patterns (CFP) can be found. Resulted from the imitation, the algorithms have biggish practical meaning, because the complexity of the system-level fault diagnosis has been greatly decreased, especially in strong t-diagnosable system.
