摘要
为了提高公铁联运物流配送客户满意度和降低物流运输成本,将物流配送过程中铁路物流配送中心、货运站(配送点)与收货点之间的路径作为优化对象,分析了公铁联运中铁路物流配送中心的配送模式,建立了以客户物流费用最低为目标的路径选择模型,考虑了各个节点之间的单位运输费用、货物在各节点的包装和储存费用以及客户对某种货物的需求量。计算结果表明:当铁路物流中心不直接向客户配送货物,而是选择货运站来配送货物时,客户物流总费用最小,因此,路径选择模型可以准确地描述物流配送问题。
To improve the customer satisfaction of logistic service and reduce the transportation cost in the united transportation of railway and highway, the paths among the distribution centers of railway logistics, freight transportation stations and customers were taken as optimal object, the distribution patterns of distribution centers of railway logistics were analyzed, a route choice model of logistic distribution with an objective function of the minimal distribution cost to customers was set up, and the unit transportation costs, storing costs and packaging costs of freights at all notes and the freight requirements of customers were considered. Computation result shows that the total cost of logistic transportation is minimal when customers receive freights from the stations rather than the centers, which indicates that the logistic distribution problem can be accurately depicted by using the model. 1 tab, 4 figs, 14 refs.
