不同运输模式下集成库存运输问题的仿真研究

以生产分销企业为背景,比较分析了生产分销网络下自营运输、第三方物流及租赁车辆外包运输模式的特征及其费用构成.通过对不同参数的不同取值进行组合,仿真分析了分销网络中单供应商、多分销商、多产品、多次直接运输策略下不同运输模式的最优解对应的总费用间的关系,重点研究了租赁车辆外包模式下参数变化对总费用的影响.结果表明在租赁车辆外包模式下装载费率对总费用的影响较其他参数更大.

Simulation Research of Integrated Inventory-Transportation Problem with Different Transportation Modes

The features and transportation cost structures of three transportation modes for an enterprise combining production with distribution are comparatively analyzed,including independent running,3rd party logistics and vehicle leasing.Under conditions that the distribution networks is composed of a single supplier,multiple retailers,multiple products and multiple direct delivery,the relationships between the total costs resulting from different optimum solutions to the transportation modes as above are analyzed combining different values of different parameters,especially how the change in parameters affect the total costs when the vehicle leasing was done in an outsourcing way.The result show that the influence of loading charge in an outsourcing way on the total cost is greater than that of any parameters else.
