Abstract: The paper uses integer programming to research repositioning of intermodal empty container of land-carriage .In the model, the objection is to minimize the cost of repositioning empty containers from port to port, from provider to port, from port to demander. It takes into consideration that the requirment of empty container from the damanders，the ability of supply of empty containers from the providers and storage ability of empty containers in the ports，load limit of empty container by varied transport methods. We adopt Lingo8.0 to solve the modle. The computing result shows that the modle can reduce the repositioning cost effectively on the condition that it satisfies the requirment from the damanders，the ability of supply from the providers and storage ability in the port etc. The modle raises the efficiency of repositioning of intermodal empty container of land-carriage by shipping companys.

Key words: container, reposition of empty container, intermodal reposition, integer programming

摘要： 本文应用整数规划的方法研究了集装箱陆上空箱多式联运调运优化问题。论文模型以场站和场站之间、供给客户和场站之间、场站和需求客户之间的空箱调运费用最省为目标函数。本文模型考虑到满足需求客户的空箱需求、供给客户的空箱供给能力限制、场站的空箱存储能力限制以及不同运输方式的运输能力限制等约束条件。应用Lingo8.0软件求解本文模型。运算结果表明本文模型可以在满足客户需求、供给能力和存储量限制的条件下有效降低陆上空箱调运费用。本文模型提高了船公司的内陆空箱调运效率。
