本研究建立一個二階供應鏈模型，包括買方與賣方。就真實世界來說，賣方若能夠提早接到買方的訂單，就更能夠有效率地發揮生產效能，進而降低生產成本與增加利潤。而若是買方提前下訂單，也能夠享受賣方提供的價格折扣，並降低購買成本。因此在本研究中，將探討前置時間對賣方收益的影響，以及價格折扣對買方購買成本的影響。本研究將顯示供應練系統可以藉由買賣雙方的整合來使得雙方獲益，並使得整個系統更有效率。

In this study we consider a simple two-stage supply chain model consisting of a single vendor and a single buyer. The buyer places orders according to an EOQ-based inventory model in order to minimize its total cost, and the vendor plans its production according to the orders received in order to maximize its total profit. In practice, if the vendor receives orders earlier, then it can plan production more efficiently which will decrease the production cost (which in turn increase the profit); also, if the buyer places orders earlier, then it may expect to have purchasing discount from the vendor which will decrease the total cost. In the supply chain model considered, we investigate both the lead time effect of order placement (provided by the buyer) on the vendor’s total profit, and the purchasing discount of pricing policy (provided by the vendor) on the buyer’s total cost. We show that the supply chain may benefit from the coordination for both parties.
