高速铁路动车组检修资源布局优化研究

高速铁路网的日趋完善,高速列车开行数量的进一步增加,对高速铁路动车组检修资源布局提出新的要求。为合理优化动车组检修资源布局,提高动车组检修效率,在分析我国动车段和动车运用所管理模式及布局方案的基础上,将动车组检修资源布局优化问题转化为基于多基地车辆路径运用的基地选址问题,基于"备选运用所-运输需求-动车组运用"间的关联关系构建动车组运用检修接续网络,建立动车组检修资源布局优化模型。以某区域的铁路网为例,利用近远期规划优化动车组检修资源布局,验证模型有效性,为今后动车组检修资源布局优化提供参考。

A Study on Layout Optimization of High-Speed EMU Maintenance Resources

With the improvement of the high-speed railway network, and the further increase of the number of high-speed trains, new requirements are put forward for the layout of maintenance resources of EMUs. To optimize the layout of EMU maintenance resources reasonably and improve the efficiency of EMU maintenance, based on the analysis of the management mode and layout scheme of EMU and EMU Operation in China, the optimization problem of EMU maintenance resources layout is transformed into the location selection problem based on multi-depot vehicle routing operation. The logic network of EMU Operation and maintenance is constructed based on the relationship among "alternative depot-transport demand-EMU operation", and the optimization model of EMU maintenance resource layout is established. Taking the railway network of a certain region as an example, this paper uses the short-term and long-term planning to optimize the layout of EMU maintenance resources, verifies the validity of the model, and provides a reference for the optimization of EMU maintenance resources layout in the future.
