多优化目标视角下高铁站到发线运用计划编制

在给定列车运行图和车站候车厅布局的前提下，研究高速铁路车站到发线运用问题。以股道和道岔的相容性约束作为前提，分析检票口附近固定座位数量和检票口与站台的通道距离，以增强车站作业计划稳定性、列车站内走行距离最短和最大化满足候车厅布局为3个优化目标，建立了到发线运用的0-1整数规划模型。针对模型特点，采用Lingo编程进行求解，最后通过某客运站为例证明该模型的有效性。结果表明，该模型能准确描述实际问题，适用于大型高铁站的股道分配问题。

Track utilization planning of high speed railway station with multi objective optimization

We address track utilization of high speed railway station for a definite train diagram and station hall layout. We analyze the number of ticket entrance nearby fixed seats and passage distance between ticket entrance and platform with compatible constraint of tracks and turnouts as a premise. We further construct a 0 1 integer programming model for arrival and departure track utilization with stability increase of station operational plan, shortest walk distance in a station and maximal station hall layout as optimization goals. Based on its characteristics, we solve it with Lingo programming.We eventually demonstrate its effectiveness with a high speed railway station as an instance. Results show that it can accurately indicate practical issues, so it is suitable for track allocation issue of large high speed railway station.
