Modeling, Analysis and Simulation on Safety Chain of Railway Bureau

Railway safety is the complicated and hot topic in the fields of intelligent railway, big data and artificial intelligent, while it is closely related to the risk point, hidden danger and accident, etc. The safety concepts and models on risk point, hidden danger and accident are provided in this paper, and the corresponding mathematical relationship are also analyzed to better manage the key safety problem. Simulation results discuss the relationship among risk point, hidden danger and accident, and the obtained results can help the safety manager to control the key safety point and improve the safety management efficiency.
