地铁网络火灾协同救援调度模型OA

The integrated dispatch of metro firefighting engines(MFEs)and trains during fire emergencies presents unique challenges due to confined tunnel spaces that restrict conventional fire truck access and the often uncertain fire location.This necessitates cross-line deployment of MFEs within the metro network.We decompose the problem into two subproblems:MFE rescue operations and evacuation of trapped trains.For each,a mixed-integer programming model is formulated.To enhance computational efficiency,we propose a line-based decomposition algorithm combined with a constraint filtering technique.The models are validated using the Suzhou metro network as a case study.Results demonstrate that the proposed approach efficiently generates solutions within practical timeframes,enabling effective cross-line MFE dispatch and rapid train evacuation.This research offers both theoretical insights and a practical decision-support tool for emergency management in metro fire scenarios,contributing significant value to metro operation safety and resilience.
