This paper develops a two-layer supply chain for defective and non-defective types of items produced by manufacturer and retailer. The manufacturer produces items on the condition that the faulty items will return to the manufacturer after inspecting without financial liability of the retailer. The damaged items are identified subsequent of the conducted full screening process and reworked by the retailer. Hence, the retailer sells the non-defective item to the customer. Effect of deterioration estimates to make this research a more realistic one for the manufacturer and retailer. This study discusses the impact of several business strategies such as production rate, unit production cost, idle time costs in a collaborative marketing system, reliability dependent demand, etc., to determine the optimum average profit of the integrated model. The selling price of the retailer, the purchase cost of the manufacturer, and holding cost has the potential to be a significant breakthrough. Numerical and managerial implications are demonstrated along with sensitivity analysis of different parameters for the proposed two-layer supply chain.

本文针对制造商和零售商生产的有缺陷和无缺陷类型的商品开发了两层供应链。制造商生产物品的条件是，有缺陷的物品经检查后将退还给制造商，而零售商不承担财务责任。在进行全面筛选过程之后，将识别出损坏的物品，并由零售商进行返工。因此，零售商将合格品出售给顾客。恶化估计的影响使这项研究对于制造商和零售商而言更为现实。本研究讨论了几种业务策略的影响，例如生产率，单位生产成本，协作营销系统中的闲置时间成本，依赖可靠性的需求等，以确定集成模型的最佳平均利润。零售商的售价，制造商的购买成本和持有成本有可能成为重大突破。拟议的两层供应链的不同参数的敏感性分析以及数值和管理意义都得到了证明。
