In order to fulfill the consumer perception to preserve the environment, enterprises must strengthen materials management of product. When companies fully focus on their core functions, materials management and reverse logistics will not become part of the company main activities. Thus materials management and reverse logistics are entrusted to an external company to get the economic profit. In this study, an overall closed-loop supply chain is entrusted by third-party logistics with forward logistics of product distribution and reverse logistics of product recovery. In order to solve the problems induced by bullwhip effect and extra costs, this study also uses consignment inventory strategy to tackle the complex closed-loop supply chain inventory system. Because suppliers must pay the cost of returned goods and commissioned third-party logistics, it will cause much cost for supplier by analysis results. This study uses consignment inventory system to shorten length of manufacturing cycle of suppliers in order to reduce inventory costs, and the retailer do not need to pay the set-up cost so that the consignment inventory system makes the overall closed-loop supply chain achieve a better efficiency.
