GO methodology is a success-oriented method for system reliability analysis. There is Dual Input Closed-Loop Feedback Link (DICLFL) considering shutdown correlation in many repairable systems. It is a problem to use the existing GO method to make reliability analysis of such repairable systems. A new GO operator, named type 9C operator, is created to describe the DICLFL considering shutdown correlation,...
To ensure the reliability and safety, hydraulic/electro-hydrostatic dissimilar dual redundant actuation system is widely used in advanced civil aircraft. Considering the change of dynamic performance of hydraulic actuator (HA) and electro-hydrostatic actuator (EHA), this paper establishes performance reliability model based on parameter drift model, and presents the calculation methods of performance...
Directing to the difficulties of fault isolation based on mathematical model, this paper presents a new fault isolation method that utilizes the limit apriori knowledge of expert, infers the failure process recursively and realizes the fault isolation with Bayes' reasoning. Through dividing the system into several levels hierarchically according to their information flow, the system failure process...
