Emergency Resource Location and Distribution of Urban Rail Transit
摘要
Abstract
In order to study the optimal location of emergency rescue stations and the distribution of res⁃cue resources to these stations in urban rail transit, the shortest rescue distance, urban land price, limit⁃ed speed of rescue conveyances in different districts, rescue time, the important stations based on the re⁃alistic operation of urban rail transit and the important stations based on the centrality relationship net⁃work were taken into consideration in setting the location model of rescue stations. Besides, the supply and demand reachability matrix was established. The location model aimed for the minimum cost of con⁃struction and rescue time. The quantity of rescue resources having been determined, the reward func⁃tions of rescue stations could be established. According to the distribution process of rescue resources with Markov Property, the optimal resource distribution model based on the maximum reward of rescue stations was established, which could be worked out by the dynamic programming with inverted se⁃quence. Finally, with the case of the planning metro network of Chengdu, 15 stations were selected as rescue stations. Meanwhile, the rescue resources distributed to some rescue stations in need were worked out. The result of the case shows that the models of location and resource distribution meet the require⁃ment of practical situation, which validates the high credibility of the model and algorithm.关键词
