考虑来料质量缺陷的供应链最优订购协调

Optimal Order Coordination of the Supply Chain with Stochastic Demand and Quality Defective Materials

针对随机需求和来料质量缺陷对供应链产生的协同效应,在制造商全检和供应商返修处理来料缺陷情形下,研究了供应商与制造商在收入共享-成本分担契约下的供应链EOQ协调问题,并与分散式、集中式供应链情形进行了对比。供应链协调时,收入共享-成本分担契约下的供应链绩效能够达到集中式供应链的绩效,其契约的成立,不受供应商批发价格及共享因子变化的影响。集中式供应链EOQ及整体利润均大于分散式供应链的情形,但风险分担却相反。研究为降低供应链内外部风险损失等成本,提供了理论依据。

Considering stochastic demand and quality defect which cooperatively affect the supply chain,we study the coordination problem based on cost-revenue sharing contract between a dominant supplier and a subordinate manufacturer under the condition that manufacture completely inspects materials from the supplier and the supplier repairs the raw materials.We compare the conditions of the decentralized,the centralized and the cost-revenue sharing supply chain.When supply chain is coordinated,supply chain performance under the contract of cos-revenue sharing can achieve the performance of the centralized supply chain.The establishment of the contract will not be affected by wholesale price or sharing factor changing.EOQ,supply chain total profit of centralized supply chain are larger than the condition of the decentralized supply chain but the total risk-sharing is reversed.The research provides theoretical basis for supply chain to reduce the costs of internal and external risk.
