Study of fault tree analysis and expert system principle

摘要

The basic concept of Fault Tree Analysis (FTA) is to select the most serious fault point or fault response in the system as the first problem to deal with. Secondly, the other secondary causes in the system fault are decomposed into intermediate events step by step until the failure causes are decomposed into basic events which can not be decomposed again. That is to say, the FTA adopts the method of decomposition and refinement step by step. The cause of the failure is stated.
