摘　　要：文章建立了有限计划时间及线性时变需求下,部分短缺量拖后的易变质物品双货栈库存模型,解决了一般情形下双货栈多周期库存问题;与已有文献中对允许缺货且缺货量完全拖后供给的假定不同,本模型假定了缺货量部分拖后供给,且短缺期间损失率与实际缺货量成正比;提出了寻求最优周期数、最优订购时刻及己有仓库和租借仓库库存降为零时刻的分析方法;最后给出了数字实例,并对该库存系统中各个参数进行灵敏度分析。This paper develops a two-warehouse inventory model for deteriorating items with a linear trend in demand and partial backlogging under the finite time horizon, which solves the two-warehouse multi-period inventory problem under the general case. Unlike the existing papers for the two- warehouse inventory problem, the present model assumes that shortages are allowed to occur and backlogged partially; and the lost rate during the shortage period is proportional to the quantities of actual backorder. An analytical solution is presented for finding the optimal replenishment policy. A numerical example is shown to illustrate the model and solution procedure, and the sensitive analysis is presented as well.
