在全线矩形天窗下提出等线、下线、下线-上线共3种高速铁路夕发朝至列车开行模式,分析每种模式下列车运行过程。以影响旅客选择行为的列车始发、终到时刻满意度、票价吸引力、影响铁路运输产品供给数量及质量的区段通过能力和运输组织难度为目标函数,构建满足变量逻辑约束、列车运行过程约束、关键地点与运行时刻约束、到发线数量约束的开行模式选择非线性整数规划优化模型,通过算例应用验证了构建模型的可行性和有效性。研究结果表明:在0:00~04:00开设全线距形天窗时,长距离列车OD应选择300km/h的动车组和等线模式,中距离列车OD应选择250km/h的动车组和下线模式。
A total of three kinds of high-speed railways such as isosceles, off-line, off-line and on-line were proposed under the full-line rectangular skylight. The evening train runs to the train running mode, and the running process of each train is analyzed. Taking the train departure, the end time satisfaction, the ticket attractiveness, the sections that affect the quantity and quality of railway transportation product supply as the objective function, the objective function is to satisfy the logic constraints of variables, train operation Process constraints, key locations and runtime constraints, to the number of hairline constraints of the open-mode selection of non-linear integer programming optimization model, validated the feasibility and effectiveness of the model through the application of examples. The results show that when the full-line skylight is opened from 0:00 to 04:00, the OD of long-distance trains should be 300km / h and the EMU and the iso-line mode should be selected. The OD of middle-distance trains should be 250km / h and the lower Line pattern.
