摘要
到目前为止,几乎所有有关两货栈(一种是己有货栈,记作OW,另一种是租用货栈,记作RW)库存问题的研究都是在确定性需求模式下展开的。然而在实际中,经常可以看到出售季节性产品的销售商在己有货栈容量不足的情况下,通过租用货栈来存贮多余的产品。因此,建立了带有两货栈的Newsvendor型产品随机库存模型。与现有的报童模型及其推广不同,现假定了库存系统有两次订购机会,给出了相关系统解的存在唯一性,同时也给出了判断系统是否需要租用其它货栈的充要条件以及模型的求解程序。最后,通过数值例子显示了本模型在实际中的应用。
Almost all the studies to date on the two-warehouse （one is an owned warehouse,denoted by OW,and the other is a rented warehouse,denoted by RW） inventory problem concentrated on the deterministic demand pattern. In practice,however,it is very common for a distributor that sells the seasonal goods with random demand to store excess inventory in rented warehouses when the storage capacity of the owned warehouse is not enough. Therefore,a stochastic inventory model is develoed for newsvendor-type products with two warehouses. Unlike the exiting newsvendor models,it is assumed that the inventory system has two ordering opportunities. The existence and the uniqueness of the solution to relevant systems are examined,and the sufficient and necessary condition of judging whether to rent RW and the solution procedure of the considered model are presented as well. At last,numerical example is implemented to illustrate the application of the model.
