摘要
借鉴径路优化方法,细化考虑车站接发车能力、始发终到能力及动车运用所存车能力等限制因素,在多商品流模型的基础上添加0-1决策变量,建立高铁枢纽车站分工优化模型,寻求高铁枢纽作业时间最小的运营组织方案.以郑州枢纽远期规划年度路网和车流数据,利用ILOG CPLEX软件求解得到车站分工方案优化结果.在求解结果基础上进行能力适应性分析,得到郑州站、郑州东站的存车能力及郑州东站的接发车能力利用接近饱和,对枢纽场站扩能改造及优化利用等决策具有一定参考意义.
Using the method of routing optimization,0-1 decision variables are added on the basis of the multi commodity flow model. Thereby,on the consideration of the departure and arrival capacity,originating capacity and storage capacity of EMU running shed,the optimization model of passenger station allocation was established to seek the operation organization plan with the minimum operation time in the high-speed railway hub.ILOG CPLEX software is used to solve the model and obtain the optimization result of station allocation plan.On this basis,capacity flexibility was analyzed. The storage capacity utilization of Zhengzhou station and Zhengzhou east station and the departure and arrival capacity utilization of Zhengzhou east station are relative higher,which is of vital importance to making decision of expansion and optimization of the high-speed rail hub station.
