铁路集装箱旅客化运输系统开行方案研究

针对铁路集装箱旅客化运输系统开行方案编制问题，采用基于备选集的优化方法，同时结合货物运输组织特点，规定了箱流物理径路和运输方案的唯一性.在考虑箱流守恒、箱流换乘、箱流运到期限，以及列车开行频率等约束的基础上，以运输企业成本最小化为目标，建立了整数线性规划模型，并设计模拟退火求解算法.最后，构建运输网络进行案例分析，验证了模型和算法的有效性.研究结果表明，与现有货物运输系统相比，新型集装箱系统充分发挥了网络运输的优势，在列车开行频率、货物送达速度和运到期限方面表现更加优异，但同时牺牲了部分列车“上座率”.

Line Plan of Passenger-like Transport System of Railway Container

Aiming at the line planning problem of passenger-like fast transport system of railway container, the optimization method on the basis of candidate train set is adopted, and the uniqueness of the physical path and the transport plan of container flow is determined according to the characteristics of freight transport organization. Considering the constraints of flow conservation, container transfer, transit period and operation frequency, an integer linear programming (ILP) model is built with the objective of minimizing the cost of transportation enterprises, and a simulated annealing algorithm is designed. Finally, a container transportation network is taken to carry out a case study, which verified the feasibility of the model and algorithm. The results show that compared with the existing freight transportation system, the new container system gives full play to the advantages of network transportation, and performs better in terms of train operation frequency and delivery speed, but at the same time sacrifices the train attendance rate.
