加线是运行图调图阶段常用的技术,加线时若能协同考虑动车组周转接续对降低动车组运用成本、提高行车组织效率具有重要意义.以区域城际高速铁路网络化运营为背景,以对既有运行图调整幅度最小化、动车组周转接续数量最大化为目标,考虑行车安全、接发车能力、动车组周转接续等约束,构建考虑动车组周转接续的多线路运行图协同加线优化模型;基于e约束法处理多目标优化问题,设计滚动时域算法以提高模型求解效率.最后,选取宁杭高速铁路、沪昆高速铁路、京沪高速铁路组成的区域城际网进行案例分析,结果表明所构建方法能够实现运行图加线与车底运用的协同优化,相比既有单线加线模式,动车组平均利用率提高9.7％.该研究能够为运行图调整提供方法支持,提高调图质量与效率.
Model for Inserting Additional Trains into Existing Timetable for Intercity Railway Network Considering EMU Connections
Inserting additional trains into the existing timetable is a commonly used method for train diagram regulations.If turnover connections of EMUs can be considered in the"train inserting"process,it is of great significance to reduce operation cost and improve train organization efficiency.In this study,based on the network operation of regional intercity railway network,an optimization model for adding trains into"multi rail lines"considering EMU turnover connections col-laboratively was proposed to minimize the adjustment of the existing diagram and maximize the number of EMU turnover connections,and take into account the constraints of train running safety,station capacity,and EMU turnover connections.Based on the epsilon constraint method to deal with multi-objective optimization problems,a rolling horizon algorithm was designed to improve the efficiency of model solving.Finally,regional intercity networks composed of Nanjing—Hangzhou,Shanghai—Kunming and Beijing—Shanghai railways were chosen for case study.The results show that the proposed method can achieve collaborative optimization of both inserting additional trains and EMU utilization.Compared to the tra-ditional inserting mode for a single line,the utilization rate of EMU is increased by 9.7％in average.This study can pro-vide methodological support and improve the quality and efficiency for the train diagram regulation.
