摘　　要：为适应区域一体化战略提出的效率、通达、均衡等交通发展目标,研究了高铁列车开行方案调整优化方法.根据区域内不同类别旅客需求特征,调整既有列车停站方案与增开列车,以最小化开行方案调整幅度、总停站次数、客流起讫点(origin-destination,OD)直达服务频率变化为优化目标,考虑列车服务、列车层次、列车调整3类约束,建立了整数规划模型.将模型线性化,使用C#语言调用CPLEX求解.长三角区域案例的结果表明:优化方案使列车层次结构分明,功能上形成分工与配合;高层级OD的快车服务频率及通勤OD的服务频率有所提升,兑现运行图后列车平均旅速提高;区域内OD直达率提高6.5%;低层级OD的服务频次和时段分布有所改善.合理调整列车开行方案有助于更好地利用区域高铁网服务旅客.To meet the transportation development goals of efficiency,accessibility,and equity proposed by the regional integration strategy,methods for adjusting and optimizing high-speed railway line plans were investigated.Based on the requirements of different passenger categories in the region,an integer programming model was proposed to adjust existing train stop plans and introduce additional operating trains.It aims to minimize the adjustments of the existing line plan,total train stops,and changes in the direct service frequency for passenger origin-destination(OD)pairs,and adheres to constraints on train service,train hierarchy,and train adjustment.After linearizing the model,C#was used to call CPLEX to solve it.The case study results of the Yangtze River Delta region indicate that the optimized plan clarifies the train hierarchy,and establishes a functional division of labor and coordination.The express service frequency for high-level OD pairs and the service frequency for commuter OD pairs are improved,and the average train travel speed is increased after implementing the timetable.The direct rate of OD pairs in the region is increased by 6.5%.The service frequency and time distribution for low-level OD pairs are improved.Reasonable adjustments to the line plan are helpful for better utilizing the regional high-speed rail network to serve passengers.
