信用支付契约是使供应链各方达到协调的重要手段。本文在单个制造商和单个零售商组成的两级供应链系统下,建立了制造商和零售商的库存控制模型,提出了联合决策零售商的订货批量,以及制造商的生产批量和定期信用支付期的启发式算法。给出了利润分配方案,以使供应链达到协调。最后,本文通过算例验证了模型和算法的有效性,为运用信用支付契约协调供应链提供了理论依据。
The credit payment contract is an important means for all parties in the supply chain to achieve coordination. This article establishes a model of inventory control for manufacturers and retailers under a two-tier supply chain system consisting of a single manufacturer and a single retailer, and proposes a joint decision-making retailer’s order quantity, as well as the manufacturer’s production volume and periodic credit payments. Heuristic algorithm. A profit distribution plan is given to enable the supply chain to coordinate. Finally, this paper verifies the effectiveness of the model and algorithm through examples, and provides a theoretical basis for the use of credit payment contracts to coordinate the supply chain.
