Fuzzy Sets and Research of the Hybrid Fault Tree Analysis and the Application in the Aerocraft Simulate Training System

In conventional fault tree analysis(FTA),the ambiguous and imprecise events such as human errors can not be handled effectively.To overcome this disadvantage,a hybrid approach employing fuzzjy set evaluation and probabilistic estimation for FTA is proposed to evaluate abnormal events.By using the method,it can effectively analyse the aerocraft Simulate Training System's failure.
