Research on Collecting Strategies in the Closed-loop Supply Chain of Engine Remanufacturing

Based on the different recovery strategy, two different models that contain a single remanufacturer and a single service station were established:a single channel recycling model and composite channel recycling model. The impact of collection price on the demand of remanufactured engine was considered, and the collection price, collection quality and profit were analyzed and compared through gambling theory analysis. The results show that the collect price and the collect quality are increasing with the increase of the effect of ollection price on the demand of remanufactured engine;The collect quality of the composite channel recycling is higher than the single channel recycling;Finally, the conclusions were validated by numerical simulation, the sensitivity was analyzed.
