摘　　要：围绕双渠道销售模式下的两货栈系统优化问题,引入随时间变化的价格因素,建立了在后进先出策略下易变质产品的库存系统优化模型;当销售价格为时间的线性增函数时,分析了后进先出策略下系统最优解的相关性质;证明了最优订购次数的存在性与唯一性,并给出租借货栈的条件;最后用数值实验验证了理论结果,并通过灵敏度分析给出系统优化的策略建议。An optimization problem of two-warehouse system under dual-channel sale modes is considered. Taking the time-varying price into account, this paper builds art optimization model of inventory system for perishable products under the last-in-first-out strategy. When the selling price of each channel is a non-decreasing linear function of time, this paper presents some optimal properties under last-in-first-out strategy and proves that the number of optimal replenishment times not only exists but also is unique. Furthermore, it proposes a sufficient condition to rent other warehouses. Finally, a numerical example illustrates the theoretical results. Accordingly some advices on strategies of system optimization are given based on sensitivity analysis.
