| Summary: | Objective Urban rail transit system is a complex integrated system involving people, machine, environment, and management, with its operational risks existing not independently or statically. Understanding the dynamic coupling effects between various risks can lead to more effective risk control, thereby reducing the probability and hazardous impact of accidents. Method Based on a systematic analysis of the risk factor sources in urban rail transit operations, both homogenous and heterogeneous risk coupling analyses for four categories of risk factors: human, equipment, environment, and management are conducted. The evolution patterns of risk coupling are summarized. Using the N-K (number of system risk factors-number of coupling factors) model, the coupling values for different combinations of the aforementioned four risk factors are quantified. Result & Conclusion Analysis of coupling value calculation for various factor combinations reveals that the more risk factors involved in coupling, the greater the risk. In dual-factor coupling, equipment has the highest impact on risk coupling, with the highest risk value in human-equipment coupling. In triple-factor coupling, equipment risks also exhibit a strong tendency to couple with other factors. Research results reflect the dynamic characteristics and the interactions of operational risks in urban rail transit system, providing valuable insights for enterprise safety management departments to develop targeted risk response strategies and management solutions. |
