摘　　要：基于客流时空分布的不均衡性,以提升整体量能匹配率为目标,分析大小交路模式下列车运行、车辆运用与折返、乘客乘车选择行为等相关约束,构建基于灵活间隔与车辆运用的大小交路运行图优化模型,提出一种基于目标分解的混合整数线性规划求解算法,并以某线路为例验证模型的可行性。优化结果表明:灵活行车间隔和大小交路方案,可从时空维度优化运能供给,提升整体量能匹配率,并有效降低站台的聚集乘客数量;采用车辆共享模式有利于减少车辆的运用成本;灵活调整行车间隔,将改变不同时段的运输能力分布,但也会增加车辆的运用数量。表明本方法具有良好的可用性及稳定性,能够为城市轨道交通列车运行图优化提供参考。Based on the unbalanced distribution of passenger flow in time and space,this paper analyzes the constraints related to train operation,rolling stock application and turnaround,and passenger travel behavior in the full-and short-length mode to improve the supply and demand matching degree.A timetabling model of full-and short-length mode based on flexible headway and rolling stock application is established,and a mixed integer linear programming algorithm based on objective decomposition is proposed.One metro line is set as an example to verify the feasibility of the model.The results indicate that flexible headway and short-length strategy can optimize transport capacity supply from a spatiotemporal perspective,effectively reducing the number of passengers gathered at the platform.Adopting a shared mode is beneficial for reducing the stock number.Flexible headway will change the headways at different periods and increase the stock number required for the timetable.It indicates that the proposed method has good applicability and stability,and can provide a reference for optimizing the train timetable of urban rail transit.
