Abstract A fault tree based system reliability method was developed to predict the failure probabilities of system components by a non-probability interval model. A non-probabilistic reliability index was developed which included reliability or safety criteria to evaluate the system reliability. Then, two sensitivity indices were developed to indicate the contribution of each basic event. This method was then used for a fault tree analysis of the unilateral asymmetric movement of an aircraft flap system. The results show that this method can accurately predict the system reliability and can accurately identify important events to provide references for optimizing the system reliability.
