Subway fire evacuation plays a critical role in modern urban safety. For the increasing frequency of fire risks and growing demands for public safety, effective rescue actions can better ensure personnel safety and reduce the risk of casualties caused by fire accidents. This study is based on the AnyLogic simulation platform and takes the Jihuying subway station in Taiyuan as a case study. Considering the spread of fire, the change in passenger behavior, and the rescue behavior of firefighters, a pedestrian evacuation model under fire that includes firefighters’ rescue behavior is constructed. Numerical simulations are conducted to investigate the impact of firefighters’ rescue time and number of rescues, as well as the speed of fire spread and different fire sources on evacuation, revealing the dynamic behavioral characteristics of pedestrians and firefighters in fire environments. Results indicate that, with a smoke spread rate of 0.15 m/s, firefighters arriving at rescue points within 50 seconds of the fire’s onset achieve the highest efficiency, and the evacuation rate increases significantly when the number of rescues reaches 12. In addition, the zoning strategy can effectively improve evacuation efficiency by strategically allocating firefighters to different areas for rescue, thereby accelerating the evacuation process and enhancing overall rescue efficiency. The research results will provide theoretical guidance for emergency response plans and evacuation design for subway fires. %K 地铁火灾， %K AnyLogic， %K 救援行为， %K 疏散效率
