基于运输成本的铁路集装箱旅客化运输系统开行方案研究

Research on the Line Plan of Passenger-like Transport System of Railway Container Based on Transportation Organization Mode

研究铁路集装箱旅客化运输系统开行方案问题,目标是设计出符合新型集装箱系统特点的开行方案,同时减少运输企业成本。提出新型集装箱系统运输组织模式,开行快速集装箱列车和区段集装箱列车实现箱流集疏运。以快速集装箱列车为研究对象,借鉴旅客列车开行方案的编制方法,结合货物运输的特点,考虑箱流守恒、箱流中转及箱流运到期限等约束,建立新型集装箱系统开行方案的整数线性规划模型,并设计自适应大邻域搜索求解算法。通过构建集装箱运输网络进行案例分析,验证模型和算法的可行性。

This paper studied the line planning problem of passenger-like transport system of railway container, in order to design a line plan that meets the characteristics of the new container system and reduce the cost of the transportation enterprise. A new transportation organization mode of the new container system was put forward, in which the fast container trains and district container trains were operated to achieve the collection and distribution of container flow. Based on the study of fast container trains, the advantages of the method for designing passenger train line plan as well as the characteristics of freight transport, an integer linear programming(ILP) model for the operation scheme of a new container system was proposed, which considered the constraints of container flow conservation, container transfer and transit period, and an adaptive large neighborhood search algorithm was designed. A case study of a container transportation network was carried out to verify the feasibility of the model and algorithm.
