结合器材供应的实际,构建了一个国家仓库-地区仓库形成的二级库存-运输系统,以最低费用为目标,建立了该系统的联合经济订购模型,求解了该系统各仓库的最佳订货量和订货次数;运用该模型对3种订货策略(年度1次订货、年度多次订货、零库存订货)进行了算例验证,表明了该模型在优化多级库存运输系统订货参数方面的意义。 According to the actual supply of equipment, a secondary inventory-transport system formed by a national warehouse and a regional warehouse was constructed. The minimum cost was taken as the target, a joint economic ordering model of the system was established, and the optimal order quantity And the number of orders. The model is used to validate the three ordering strategies (annual order, annual order, zero stock order), which shows the significance of the model in optimizing the order parameters of multi-level inventory transportation system.
