基于销售奖励与回购契约的供应链协调机制研究

Study on the Supply Chain Coordination Mechansim Based on Sales Rebate and Buy-back Contract

在单一供应商和单一零售商组成的两级供应链中,引入销售奖励机制建立起由供应商承担运输成本的回购契约模型,分析了供应链双方在是否存在回购契约情况下的最优决策,并推导出在回购契约下零售商的最优订货量与供应商的回购价格。通过算例验证了回购契约下双方的最优决策能够使得供应链整体利润达到最优。

The paper establishes a buy-back contract model that incorporates sales rebate mechanism for two-echelon supply chains that consist of a single supplier and a single retailer, with transport cost borne by the supplier. It analyzes the optimal decisions for the two parties both with and without the buy-back contract and arrives at the optimal ordering quantity for the retailer with the buy-back contract and the buy-back price for the supplier. A subsequent numerical study verifies the optimal decision as being capable of maximizing the overall profit of the supply chain.
