零售商提前订货是一种供应链协调策略，即零售商向供应商订货时，订货提前期大于从供应商到零售商的正常的供货提前期.本文讨论一个由单一供应商和多个零售商组成的供应链，其中供应商采用基于提前订货时段的折扣方法引导零售商提前订货.通过建立相应的数学模型，分析了零售商如何确定提前订货的最佳时段，以及供应商如何确定最优的折扣方案.

Optimal early order commitment discount in a supply chain with one supplier and multiple retailers

Early order commitment is one of the strategies for supply chain coordination, wherein a retailer commits to purchase a fixed-order quantity and delivery time from a supplier before the real delivery occurs. In this paper, an analytical model is developed for a supply chain with one supplier and multipleretailers, where the manufacturer uses a wholesale price discount scheme based on retailers' early order commitment periods to induce the retailers to commitment their orders in advance. This model can be used to determine the optimal early commitment periods for the retailers, and to determine the optimal discount scheme for the supplier.
