本文采用定期库存控制策略研究了需求服从均匀分布、订货周期与再制造周期不相等情况下的含有管理复原退货物流的库存问题。在考虑退货价格对需求的影响的情况下,本文建立了以使期望利润最大化为目标,对退货价格、订货量、订货周期和再制造周期进行同时进行决策的库存模型。本文通过数值算例分析了退货价格对需求的影响因子的大小以及退货率的大小分别对利润、最优退货价、最优订货量、最优订货周期和最优退货处理周期的影响。结果指出,商家在制订库存策略时应该考虑退货价对需求的影响,并且应首先确定退货率和退货价对需求影响因子的大小。
This paper explores an inventory management problem with managed-recovery return logistics through the regular inventory control policy. Considering the influence of the return price on the demand, we build an inventory model to decide the optimal the return price, order quantity, the order cycle and the remanufaeturing cycle, with the objective of maximizing the expected profit. Numerical examples are provided to analyze the influence of the return price and the return rate to the demand, order quantities, the order cycle and the remanufacturing cycle, etc. We find that the manager should consider the influence of the return rate and the return price on the demand when making decision on the inventory policy.
