摘　　要：铁路集装箱客运化系统对于改善我国铁路集装箱运输效率和提升铁路在高附加值货物运输市场的竞争力具有重要意义。在客运化系统中,集装箱班列的停站方案与运行图是班列运输组织计划的核心内容,前者确定各班列的停站模式,后者确定班列在各车站的出发与到达时间,二者之间相互影响,共同决定服务质量。因此,为提升运输组织计划编制效率,有必要在基于铁路通道的运营环境下,研究考虑不同运行区段的集装箱客运化班列停站方案与运行图协同优化问题。在满足箱流需求与符合列车运力的前提下,考虑具体的集装箱至列车的分配,将列车停站方案约束嵌入到列车运行图编制过程中,一方面使得停站方案与箱流分配方案相协调,另一方面保证列车在站停留时间能满足集装箱装卸作业的要求。以总列车停站时间最小为目标,综合考虑货物运到期限、车站到发线资源的分配、列车追踪间隔时间以及列车停站时间等约束,构建混合整数线性规划模型,并借助优化求解器CPLEX对模型进行求解。以实际中欧班列通道为案例进行实证分析,验证提出方法的有效性。实验结果表明,客运化系统能够充分发挥网络运输的优势,在仅牺牲部分列车能力利用率的前提下,具有列车开行频率高、运输集装箱数量多以及运到期限短的优点。The railway container system under passenger transport mode could significantly improve the efficiency of railway container transportation and enhance the competitiveness of railways in the high valueadded freight transport market in China.In this system,the stop plan and timetable of container trains were the critical parts of the train transportation organization plan.The former determined the stop patterns of each train,while the latter specified the departure and arrival time of each train at each station.The two plans interacted with each other and jointly determined the service quality.Therefore,to improve the efficiency of transportation organization planning,it was necessary to collaboratively optimize the stop planning and timetabling for container trains under passenger transport mode considering different operation zones in the railway corridor environment.On the premise of meeting the requirements of container demands and train capacity,the specific container-to-train assignment was considered,and the train stop plan constraints were embedded into the train timetabling process,in order to make the train stop plan consistent with the container distributions,and simultaneously ensure that the container loading and unloading operations can be completed within the dwell time at stations.With the objective of minimizing the total train dwell time,the mixed-integer linear programming model was formulated by comprehensively considering the constraints of the transit period,the allocation of arrival-departure tracks,the train tracking interval time and the train dwell time.The CPLEX solver was adopted to produce the solutions.The numerical experiments were implemented on a real-world railway corridor to demonstrate the effectiveness of the proposed method.The results show that the new container system can give full play to the advantages of network transportation,and has the characteristics of high train frequency,large number of transported containers and short transit period,while sacrificing only a portion
