高速铁路车站列车进路分配链式优化研究

A Study on Optimization of Train Route Chain Allocation in High-Speed Stations

为满足高速铁路车站作业的高效性、稳定性以及站内相关行车设备运用的合理性,分析列车进路作业,考虑到轨道电路分段解锁的实际特性,结合列车作业链的思想,以均衡到发线设备时空应用和提高车站作业计划的稳定性为目标,建立列车进路链式分配模型。以某高速铁路车站为例,基于列车时刻表到发时序,采用贪婪模拟退火算法求解,对列车相关作业链进行空间序列分配。实验结果表明,采用该模型能提高站内设备运用的均衡性,保障站内列车运行的稳定性,为进路分配策略提供了研究支撑。

To ensure efficient and stable operation in the high-speed railway stations as well as the optimal utilization of station equipment, this paper analyzes the train route operation and builds a train route chain allocation model, taking into account the characteristics of the track circuit segment unlocking, combining the idea of train operation chain, with the target of balanced spacetime application of arrival and departure track facilities and improved stability of station operation plan. Taking a high-speed railway station as an example and based on the premise of the arrival and departure sequence of the train schedule, the spatial sequence distribution of the train-related operation chain is performed using Greedy Simulated Annealing Algorithm to find the solution. Simulation results show that this model can help balance equipment utilization and ensure the stability of train operation in the station, which provides research support for route allocation strategies.
