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。 Aiming at the optimization of two warehouses system under the double channel sales model, this paper introduced the price factor changing with time and established the inventory system optimization model of the perishable products under the backward-first-out strategy. When the sales price is a linear increasing function of time, Finally, the theoretical results are validated by numerical experiments, and the results of sensitivity analysis are given System optimization strategy recommendations.
