基于延期支付的再制造闭环供应链协调研究

Research on Remanufacturing Closed-Loop Supply Chain Coordination Based on Delay in Payments

为探究延期支付这种商业信贷形式对再制造闭环供应链的作用,本文构建了由一个制造商,一个回收外包商和市场构成的闭环供应链系统,并建立了外包商不采用延期支付策略和采用延期支付两种情况下,各利益主体的利润模型以及供应链的总利润模型,得出供应链利润最优时制造商的订货次数和再制造比例。通过算例,在采用或者不采用延期支付策略,以及延期支付期限确定或者变动情况下,结合制造商的再制造比例,分析了各利益主体利润的变化情况,最后提出管理启示。

In order to explore the impact of Delay in Payments, a kind of trade credit forms, on remanufacturing closed-loop supply chain, we establish a closed- loop supply chain system composed of one manufacturer, one recycling outsourcer and market. Consideringtwodifferent situations of employing the strategy of Delay in Payments or not, we develop the profitmodels of all members as well as the whole supply chain, and derive the optimal order times and remanufacturing proportion.Through example, we analyze the profit fluctuation of each member with or without Delay in Payments strategy, as well as under a determined or fluctuated Delay in Payments period. At last, we put forward management implications.
