基于订货量延期付款条件下的订货策略研究

Replenishment Decisions Under Permissible Delay in Payments Linked to Order Quantity

为了激励零售商的购买行为,供应链中常常通过延期支付策略来增大整体利润。在已有研究成果的基础上,打破了传统研究中产品补货率无限大的假设,在与订货量相关的延期支付条件下,从零售商的角度出发,提出了补货率有限时的最优补货策略;通过具体的算例,阐述了最优补货策略的确定过程;运用灵敏度分析的方法,分析了最小订货量、支付期限和产品补货率的变化对最优补货策略的影响。

In supply chain management, suppliers usually provide permissible delay in payments to stimulate the retailers in order to increase the profits of the whole supply chain. From the retailers＇ viewpoint, this paper proposes the optimal replenishment decisions based on literatures existed when the replenishment rate is finite under permissible delay in payments linked to ordering quantity. Finally, several numerical examples are given to illustrate the theoretical results. In addition, sensitivity analysis approach is used to analyze the effect of the minimum order quantity, the trade credit period and the replenishment rate on the replenishment decisions.
