Availability simulation model of complex electromechanical systems with the consideration of testability parameters

摘要：

　　This paper proposes a stochastic MFBD (maintenance function block diagram) to describe fault diagnosis dynamic behavior of availability fluctuation evaluation for complex electromechanical system, which considers comprehensive diagnostic parameters, maintenance process and resource.The availability evaluation of complex electromechanical systems is achieved by simulation method.Firstly, the faults are divided into several types according to the quantity relationship represented by testability parameters and the logic sequence of fault-related activities is modeled.Math models describing the uncertainty between activities are established,which are embedded within MFBD.The stochastic MFBD is transformed into a simulation model designed via PI (process interaction) algorithm.Finally, a discrete-event simulation example for availability analysis of complex electromechanical system is provided and the accuracy and applicability of the proposed method are verified.
