A Remanufacturing Strategy for the Closed-loop Supply Chain under Patent Protection
摘要
Abstract
Due to high demand in many raw material markets and the increased awareness of the environmental impact of disposal, the recycling of end-of-life (EOL) products has attracted much attention. By remanufacturing and remarketing used products, a company can obtain enormous social and economic benefits. However, in the patent perfect market the original manufacturer is protected by patent products and owns the exclusive right to remanufacturing. The third-party manufacturers cannot remanufacture used products until the original manufacturer's patent licensing expires. The current literature primarily discusses the remanufacturing-related intellectual property protection from legal perspective. There is a lack of literature in this area from managerial perspective. In the face of competition with remanufacturers, the original manufacturer often adopts two strategies to minimize the loss of potential benefits: remanufacturing or recycling. There is little literature about the use of intellectual property protection to to help the original manufacturer compete with the remanufacturer of used products. This paper discusses different remanufacturing strategies of the original manufacturer for both new products and remanufacturing products. A closed-loop supply chain model is established to examine the impacts of patent licensing in a decentralized system in which the retailer is responsible for products recovery. We assume that the original manufacturer adopts different remanufacturing strategies to protect its patent; no remanufacturing (iV strategy) , original manufacturer remanufacturing (0 strategy) and authorized third-party remanufacturing (A strategy). The results show that remanufacturing of used products can increase profit for all supply chain parties when new products and remanufactured products have same quality regardless of remanufacturing strategies. Under the licensing strategy, the original manufacturer can change patent licensing fees to influence the decision-making of the third-party remanufacturer. In comparison, the original manufacturer would authorize third-party remanufacturer to remanufacture used products when the remanufacturing cost of the third party remanufacturer is low. In this case, the original manufacturer approves the third-party manufacturer to remanufacture used products. This strategy not only can enhance the profits of the original manufacturer and its retailer, but also improve the performance of the closed-loop supply chain system. In summary, the patent licensing of remanufacturing is a strategic approach for the original manufacturer to obtain technological study can provide theoretical contributions and practical implications for the original manufacturer to improve its remanufacturing decision-making effectiveness in the closed-loop supply chain. gains. This paper adopts the game theory to study the closed-loop supply chain model for patent protection. The major findings of this关键词
