Coordination Research For The Dual-channel Closed-loop Supply Chain With Remanufacturing Under Patent Authorizing

In recent years, the rapid development of global economy and the great progress of material wealth’s creative level have influenced the ecological environment seriously,and the natural resources have been consumed heavily. Based on the concept of environmental protection and resource conservation, the remanufacturing activities of waste products have aroused extensive attention; the progress of Internet technology has speeded up the development of electronic commerce; more and more consumers begin to use network platform to buy products; supply chain members realize the dual channel mode which is combined by online direct sales channel and traditional retail channel as their important strategic development model. Combing waste products’ remanufacture and dual-channel supply chain mode, this paper mainly studies the coordination for dual-channel closed-loop supply chain with remanufacturing under patent authorizing.Firstly, a dual-channel supply chain model without remanufacturing and a dual-channel closed-loop supply chain model with manufacturer remanufacturing were established as reference comparator, the uncooperative dynamic game’s optimal decision-making of the two models were compared and analyzed. The result shows that the mode without remanufacturing is inferior to the mode with manufacturer remanufacturing; the decrease of remanufacturing comprehensive cost can increase the supply chain’s revenue.Secondly, taking retailer remanufacturing under patent authorizing into consideration, a dual-channel closed-loop supply chain model with a manufacturer and a retailer was established. The uncooperative dynamic game’s optimal decision-making of the model with retailer remanufacturing and the above two reference model were compared, it finds that no remanufacturing mode is inferior to retailer remanufacturing mode; retailer remanufacturing mode is better than manufacturer remanufacturing mode when the retailer’s comprehensive remanufacturing cost is low enough. Analyzing the optimal decision-making of uncooperative dynamic game model and joint decision-making model, the supply chain system has efficiency loss in the case of uncooperative dynamic game. Therefore, a two-part tariff contract was designed to ameliorate the uncoordinated situation. The above conclusion and the effectiveness of two-part tariff contract were verified through numerical examples.Thirdly, taking third-party remanufacturing under patent authorizing intoconsideration, a dual-channel closed-loop supply chain model with a manufacturer, a retailer and a third-party were established. As the above, taking the optimal decision-making of uncooperative dynamic game model, two reference models, joint decision-making model into comparison and analysis, the following conclusions can be drawn out: no remanufacturing mode is inferior to third-party remanufacturing mode, if the third-party’s comprehensive remanufacturing cost is low enough, its remanufacturing mode is better than manufacturer remanufacturing mode; the efficiency loss of dual-channel closed-loop supply chain was leaded by uncooperative dynamic game decision-making, a two-part tariff contract was designed to make up for such efficiency loss; numerical examples was used to verify the above conclusion and the effectiveness of two-part tariff contract.Finally, the main conclusions of the research are summarized, and future work is pointed out for further investigation.
