摘要: 为解决运输与库存成本存在“二律背反”难以实现总物流成本最小的问题,建立了集仓储与运输一体的物流经济运输批量模型,对模型进行分析求解。研究发现,仓储和运输一体化系统最优成本是关于物流需求率的分段函数;当装载量无限大,铁路的规模运输效应优于公路运输;当装载量一定时,选择何种运输方式应该综合考虑物流需求率与装载量、单位运输成本和库存成本之间的关系。本文的结论对承运方选择运输方式提供了理论参考。

Abstract: In order to reduce the negative influences of "Trade-off" between inventory cost and transportation cost, the problem of transportation mode selection when there is a limitation of loading capacity is studied. By referring to the economic order quantity (EOQ) model, an economical transport quantity method is also proposed, of which inventory cost and transportation cost are both taken into account. Study shows that the optimal cost of the integrated system of warehousing and transportation is a piecewise function which depends on logistics demand rate; when the loading capacity is infinite, the scale transportation effect of the railway outperforms that of road transportation; when the loading capacity is a constant, the relationship of logistics demand rate and loading capacity, unit transportation cost and inventory cost, should be considered comprehensively when selecting a transportation mode. The proposed method provides a theoretical reference for the carrier to choose the transportation mode.

Key words: integration of warehousing and transportation, economical transport quantity, multi-modal transportation
