摘要

吸引区划分是铁路车站间货流分布和组织的基础。铁路集装箱码头作为大型铁路货物集散中心，其发展与当地城市的物流规划和经济发展密切相关。本文采用重力模型、断点模型和加权voronoi图，结合SPSS软件和ArcGIS软件对内陆铁路集装箱码头货流吸引区进行划分。然后在成本最小和时间窗口限制的目标下，建立了内陆码头与吸引区之间货流组织优化的0-1整数规划模型。最后，以哈尔滨铁路集装箱码头为例，验证了模型在不同运输方式、不同速度下的可行性。结果表明，在合理选择支线节点到铁路集装箱码头的运输方式时，有必要划分吸引区。提高支线运输速度是提高货运量、增加铁路收入、实现中铁快运可持续发展的有效途径。

ATTRACTION AREA DIVISION AND FREIGHT FLOW ORGANIZATION OPTIMIZATION OF INLAND RAILWAY CONTAINER TERMINAL

The attraction area division is the foundation of distribution and organization of freight flow among railway stations. The development of railway container terminal, large railway freight distribution center, is closely related to logistics planning and economy development of local city. In this study, we divide freight flow attraction area of inland railway container terminal by using gravity model, break-point model and weighted-Voronoi-diagram with SPSS and ArcGIS. And then under the target of minimal cost and time window limitations, we develop 0–1 integer programming model for freight flow organization optimization between inland terminal and its attraction area. Finally, this paper takes railway container terminal in Harbin as an example to test model feasibility under different speeds from different transportation modes. The results show that it is necessary to divide attraction area when choosing reasonable transportation mode from feeder nodes to railway container terminal. The improvement of feeder transportation speed is an effective method to improve freight volume, increase railway revenue and realize sustainable development of China Railway (CR) Express.

期刊介绍： At present, transport is one of the key branches playing a crucial role in the development of economy. Reliable and properly organized transport services are required for a professional performance of industry, construction and agriculture. The public mood and efficiency of work also largely depend on the valuable functions of a carefully chosen transport system. A steady increase in transportation is accompanied by growing demands for a higher quality of transport services and optimum efficiency of transport performance. Currently, joint efforts taken by the transport experts and governing institutions of the country are required to develop and enhance the performance of the national transport system conducting theoretical and empirical research. TRANSPORT is an international peer-reviewed journal covering main aspects of transport and providing a source of information for the engineer and the applied scientist. The journal TRANSPORT publishes articles in the fields of: transport policy; fundamentals of the transport system; technology for carrying passengers and freight using road, railway, inland waterways, sea and air transport; technology for multimodal transportation and logistics; loading technology; roads, railways; airports, ports, transport terminals; traffic safety and environment protection; design, manufacture and exploitation of motor vehicles; pipeline transport; transport energetics; fuels, lubricants and maintenance materials; teamwork of customs and transport; transport information technologies; transport economics and management; transport standards; transport educology and history, etc.
