Research on fire risk assessment of subway operation based on fuzzy analytic hierarchy process

Fire is one of the most common accidents during subway operation. Once the fire risk is not reasonably controlled, it is very easy to cause serious casualties and property losses. In order to scientifically evaluate the fire risk level of subway operations and provide effective fire safety management measures for operating companies, this article systematically builds a four-tier system from the perspective of human factors, management factors, environmental factors, and equipment factors involved in subway operations. The subway operation fire risk evaluation index system is composed of three first-level indexes and 32 second-level indexes, and the weight of each index is calculated based on the analytic hierarchy process. Secondly, the fuzzy comprehensive evaluation method is used to give the calculation steps of the fire risk of subway operation. Finally, the model is used to conduct an empirical analysis of Metro Line 2 in a provincial capital city in Southwest China. It is concluded that the overall risk level of the subway line is level II, indicating that the fire risk of its operation is relatively small. The evaluation result is consistent with the actual operation of the subway line, indicating that the evaluation method has a certain applicability and effectiveness.
