灾害条件下山区旅客列车径路优化研究

Study on Route Optimization of Passenger Trains in Mountain Area under Disaster

通过阐述灾害对旅客列车径路选择的影响,分析合理径路集的选择方法,以最小广义费用为目标、以灾害条件下可用通过能力为限制约束条件,建立灾害条件下山区铁路旅客列车的径路选择模型。并选用基于能力充足的K-短路算法对模型进行求解,最后结合matlab软件对相应的算例进行了求解。

Through expounding the influence of disaster on route selection of passenger trains, the selection method of reasonable route sets is analyzed in this paper. Taking minimum generalized cost as object and the available passing capacity under disaster as restriction condition, the route selection model of railway passenger trains in mountain area under disaster is established. Then, the model is solved by using the K-short route algorithm with enough capacity, and the solution on corresponding example is taken by combining with matlab software.
