摘要
在单品种货物随机存贮模型的基础上,建立了两层次、多品种货物的随机存贮模型.系统费用由货物运输费、存贮费和缺货损失费三项组成.货物运输费又由中心仓库运到各分拨仓库的运输费用和各分拨仓库之间由于互相调拨而发生的运输费用两项构成.利用数学方法对该模型进行了求解,确定了各货物在分拨仓库的最优库存量.并通过算例分析,讨论了不同期初库存水平下,各分拨仓库之间应互相调运各物资的数量.
Based on the stochastic inventory model of single goods, the two-hierarchy stochastic inventory model with multi-varieties was established. In this inventory system, the total costs was composed of goods transport costs, storage costs and loss costs due to lack of goods. The transport costs consisted of the costs of goods transported from the central warehouse to the sub-depots, and that of the goods transshipped among the sub-depots. After the expenses structure of this inventory system was analyzed, the expenses expression was established. By using the mathematic methods and computer simulation, the optimization stocks of different goods could be determined. And the transshipment amount of different goods among the sub-depots under the different stock levels was analyzed through a practical example.
