| Abstract: | An object-oriented method of computer aided failure mode and effect analysis (CFMEA) was presented. The simulation modular of control system was established, in which the data, performance and mapping relation were encapsulated in component model and typical control modular. Through causal reasoning at attribution between objects, it is easy to transfer the CFMEA results into corresponding fault tree so as to realize the reliability analysis for control system. In the control system modeling, the dynamic performance in reliability model was inducted, its solution method based on simulation was provided. The application results indicate that the reliability analysis based on simulation modular is effective and easy to combine the advantage of system function and performance. |
