高铁枢纽车站到发线运用与进路选择综合优化研究

通过分析高铁枢纽车站接发列车和客运作业的特点,考虑接发列车技术要求和现场客运组织要求,将到发线运用和进路选择作为整体进行综合优化,以到发线运用和检票口作业量均衡、接发列车受交叉干扰程度最小为优化目标,建立0-1整数规划模型,并针对实际问题设计蚁群算法求解。最后以广州南站为案例进行分析,结果表明各到发线接发列车数量和检票口作业量较为均衡,占用同一到发线相邻两列车最小时间间隔较为合理,有利于列车运行受到干扰时接发股道和时间的调整,达到了优化到发线运用和进路选择的目的。

Comprehensive optimization for utilization of arrival-departure tracks and route selection in hub-station of high-speed railway

Through analyzing characteristics of arrival and departure of trains as well as passenger services, and considering technique requirements of train arrival & departure and passenger organization in high-speed railway hub-station, the use of arrival departure track and route selection were taken as a whole to be optimized comprehensively. Aiming at the equilibrium use of arrival departure track, the equilibrium workload of ticket check entrance, and the minimum conflict of train arriving and departing, the 0 1 integer programming models were established. Meanwhile, the ant colony algorithm was designed to solve practical problems. Taking Guangzhou South station for an example, results showed that the utilization of arrival departure tracks and the workload of ticket check entrances were more balanced, and the minimum time interval of two trains which occupied the same arrival departure track was more reasonable, which was beneficial to the adjustment of track and time when the train was delayed and disturbed, achieving goals of optimization for utilization of arrival departure tracks and route selection.
