Failure Propagation Analysis of Complex System Based on Multiple Potential Field

摘要

In consideration of the complex system structure and its functional behavior, a method of analyzing the system failure propagation process based on multiple potential field model is proposed, for the sake of seeking out all the possible failure propagation paths with their lengths if faults occur. Firstly, the structure and functional behavior of the complex system is introduced based on the complex network model. Secondly, system failure properties are analyzed and the whole process of system propagation is simulated based on the proposed failure propagation model. Finally, a case study based on railway train bogie system has been implemented to demonstrate the proposed method, which shows that the proposed model and method work well on the complex system.
