摘要

规模和距离因素决定了非整车运输的经济性。针对轮辐网络中规模-距离权衡问题，提出了一种三段式的轮毂定位方法。基于业务规则的预处理确定直接运输和中心转移的货物数量。提出了一个包含递进传输速率的0-1整数规划模型。动态运输费率被用来最大化适用的规模和距离经济，通过最佳匹配货物流和车辆类型。以国内一家领先的小货车公司为例进行了研究，结果表明了该方法的有效性。

A method for the hub location problem of scale-distance tradeoffs

Scale and distance factors determine the economies in less-than-truckload transportation. A 3-stage method is presented for the hub location problem of scale-distance tradeoffs in a context of hub-and-spoke network. A business-rule based preprocessing determines cargo quantities shipped directly and hub-transferred. A 0-1 integer programming model incorporating stepwise transport rates is proposed. Dynamic transport rates are utilized to maximize applicable scale and distance economies by best matching cargo flows with vehicle types. A case from one leading less-than-truckload company in China is studied and results demonstrate the effectiveness of the proposed method.
