摘要: 在成熟期的存货影响销售环境下,考虑销售率线性依赖瞬时库存水平,不允许缺货,研究了一类非变质性物品的两货栈库存决策问题.建立了以系统平均总利润最大为目标的决策模型,分析了系统最优库存策略的存在性和唯一性,并给出了求解模型的有效方法.分析结果表明,库存管理者利用租用货栈进行订货决策时,除了要充分考虑企业自身的库存容量外,还取决于自有货栈产品相关参数对库存系统绩效的边际贡献率.

Abstract: In the product mature period, a two-warehouse inventory problem is investigated for single product with stock-dependent selling rate, which is linearly dependent on current stock level. Shortages are not allowed. The decision model with the goal of maximizing the total average profit is developed, the existence and uniqueness of optimal replenishment policy are showed, and then a simply solution procedure for optimal strategy is given. The number results are listed: when rented warehouse policy is used, inventory managers not only fully consider their own inventory capacity, but also consider some related own warehouse inventory parameters’ margin contribution ratio.

Key words: inventory, two warehouse, linear form stock-dependent selling rate, mature period
