Reliability Analysis of Equipment System Based on State Transition Method

Abstract

The repairable system with dynamic random fault are often analyzed with static approximation processing method, which will result in the great differences between calculated value of the reliability index and the actual situation. In this paper, aiming at the dynamic analysis problem, the state transition equation in which the reliability parameters of system component are changed with time will be established applying the markov process theory. The corresponding mathematical model was established according to the principle and operation characteristics of a certain equipment system, and the method was analyzed using the example. The analysis results show that the model can reasonably analyze and calculate the changes of unreliability of a certain equipment system along with time. The markov state transition algorithm is effective and practical method, and it will promote the application and development of the dynamic reliability analysis technology in equipment system.
