地铁消防应急救援站点选址优化研究

为了增强广州地铁轨道交通消防应急能力，通过构建数学模型，对地铁消防应急救援站点优化选址进行研究，首先建立考虑广州地铁轨道实际情况的限制时间模型和必选与非选站点模型，接着利用Lingo 18.0软件对限制时间模型进行求解，再利用必选与非选站点模型进行优化，对于被重复覆盖的消防应急救援服务需求站点，选择距离最近的地铁消防应急救援站点作为需求站点的消防应急救援力量出发站点。最后从241个地铁站点中选出40个站点作为地铁消防应急救援站点，实现对所有地铁站点救援服务覆盖。

Study on site selection optimization of metro fire emergency rescue station

In order to enhance the fire emergency capability of Guangzhou metro rail transit, a mathematical model was built to study the optimal site selection of metro fire emergency rescue stations. First, a time limit model and a required and non-selected station model were established considering the actual situation of Guangzhou metro rail. Then, Lingo 18.0 was used to solve the time limit model, and then the required and non-selected station models were used to optimize. For the repeatedly covered fire emergency rescue service demand stations, select the nearest metro fire emergency rescue station as the departure station of the fire emergency rescue force of the demand station. Finally, 40 stations from 241 metro stations were selected as metro fire emergency rescue stations to achieve the coverage of rescue services for all metro stations.
