【摘要】：在铁路干线能力释放、铁路运输物流化快速发展的大背景下,分析了铁路运输的市场状况,包括铁路运输的优势和短板,分析了电商平台等互联网元素的加入和物流中心的建立对铁路运输的影响,简述了铁路运输产品应对市场化需要的升级换代。对全程货物运输计划、零散货物快运和铁路货运服务网络的基础理论进行了较为详细的分析,总结了各自的特点,列举了快运班列面向的货物品类,对全程货物运输计划下的快运列车的作业过程进行了较为详细的阐述。建立了车流接续模型,以在站停留时间和运输费用作为目标函数,加入了班列开行约束、运到期限约束、运行线能力约束。最后在模型中加入了不确定性约束条件,给出了将不确定性模型转化为确定性模型的方法。通过算例对模型进行了较为全面的分析和验证,从数据预处理开始,对车流的拆分方法进行了详细说明,针对具体情况,定量分析了不同班列最小开行车辆数和车流在站停留时间的关系,得出了较为合理的班列开行最小车辆数。模型求解结果的重点是得出如何对车流进行拆分和如何对车流进行分配,即将每一支由各个技术站产生的初始车流拆分成一个个子车流,然后又将子车流分配到各个班列中去。考虑了车流总量超过路网总能力和未超过总能力的情况,在超过总能力时,根据求解结果合理滞留超出路网能力部分的初始车流,在未达到路网能力时,根据计算结果安排车流,删除未分配车流的运行线,再根据各个初始车流的生成时间,在不改变车流组织的情况下调整运行图,使得车流在站停留时间减少。最后加入不确定货源,得出不同计划兑现率下的车流在站停留时间以供对比参考。从跨局快运路网中选取京广快线进行分析计算,对京广快线沿线技术站的管内班列的运输组织进行分析,得出相应跨局车流运输需求，，在给定列车时刻表的情况下得出合理的车流组织,并对运行图进行运行线删除和调整。
[Abstract]:Under the background of the release of railway trunk line capacity and the rapid development of railway transportation logistics, the market situation of railway transportation is analyzed, including the advantages and disadvantages of railway transportation. This paper analyzes the influence of the addition of Internet elements such as e-commerce platform and the establishment of logistics center on railway transportation, and briefly introduces the upgrading of railway transport products to meet the needs of marketization. This paper analyzes in detail the basic theories of the whole cargo transport plan, the scattered freight express transportation and the railway freight service network, summarizes their respective characteristics, and lists the categories of goods facing the express transportation classes. The operation process of express train under the whole cargo transportation plan is described in detail. The train flow continuity model is established, which takes the station residence time and transportation cost as the objective function, and adds the train running constraints, the delivery term constraints, and the running line capacity constraints. Finally, the uncertain constraints are added to the model, and the method of transforming the uncertain model into the deterministic model is given. The model is analyzed and verified by a numerical example. Starting from the data preprocessing, the separation method of the traffic flow is explained in detail, aiming at the specific situation. The relationship between the minimum number of vehicles in different trains and the residence time of train flow at the station is quantitatively analyzed, and a reasonable minimum number of vehicles is obtained. The key point of the model solution is how to split the traffic flow and how to distribute the traffic flow, that is, the initial traffic flow generated by each technical station is split into a sub-flow, and then the sub-flow is allocated to each class train. Considering that the total traffic volume exceeds the total capacity of the network and does not exceed the total capacity of the network, when the total capacity is exceeded, the initial traffic flow beyond the capacity of the network is reasonably retained according to the result of the solution, and when the capacity of the network is not reached, According to the result of calculation, the traffic flow is arranged, the running line of the unallocated traffic flow is deleted, and according to the generating time of each initial traffic flow, the operation diagram is adjusted without changing the traffic flow organization, so that the train flow residence time in the station is reduced. Finally, by adding uncertain sources of goods, the stop time of traffic flow at the station under different planned delivery rates is obtained for reference. From the analysis and calculation of Beijing-Guangzhou Express Line selected from the inter-bureau express network, the transportation organization of the in-line train of the technical station along the Beijing-Guangzhou Expressway line is analyzed, and the corresponding cross-bureau traffic flow transportation demand is obtained. The reasonable train flow organization is obtained under the condition of given train timetable, and the running line of operation diagram is deleted and adjusted.
