基于数量折扣的改良品供应链协调策略

Supply Chain Coordination Strategy for Ameliorating Items Based on Quantity Discount

本文以改良品供应链为研究对象,采用数量折扣作为激励机制,研究了一个供应商和一个零售商构成的改良品二级供应链在批量对批量供应模式假设下的协调问题,以达到协调改良品供应链的目的。通过算例分析,发现基于数量折扣的改良品供应链协调策略有效地实现了改良品供应链的协调。最后对改良品供应链的改良率和市场需求率进行了敏感性分析,研究了它们对供应链的影响。

A two-echelon supply chain of ameliorating items consisting of a retailer and a supplier is presented in this paper to achieve the supply chain coordination.The coordination problem of the supply chain is studied by taking quantity discount as incentives under the assumption of the lot-for-lot policy.It can be found that the optimal strategy is achieved with quantity discount provided by the supplier.The numerical example is given to illustrate that the optimal strategy is very effective in improving the coordination of the supply chain.The sensitivity of the total cost of the supply chain with respect to amelioration rate and demand rate has also been presented at last.
