Reliability and safety analysis of cross-redundant Structure based on Markov Process
The structure of cross-redundant is used to in railway signaling safety-critical system with the development of railway integration and automation. In this paper, a modeling method is studied for analyzing the reliability and safety of crossredundant structure by the effects of maintenance, failure checking cover ratio and common cause failure based on Markov process. The failure rates of subsystem are divided into several independent parts according to the feature and the independent of subsystem of signaling system. System decomposition and compression are applied to solve the problem of state proliferation. Finally, Quantity analysis and simulation are realized. The method will be beneficial for the modeling and analysis of railway signaling system for reliability and safety and may be applied for other systems.
