An Analysis And Research On Automotive Engine Remanufacturing Recovery And Influencing Factors

Engine remanufacturing which is the part of automotive parts remanufacturing has been regarded as an important industry to promote the development of the recycling economy.Nowadays, the lack of the recovery of obsolete engine restricts the development of the engine remanufacturing industry, and the recycling strategies play a decisive role in the recovery of obsolete engine, then they affect the supply chain performance. Therefore, recovery strategy has already caused the extensive concerns of the academic and business circles. This paper analyses and research the cause of recovery from the internal and external parts of the closed-loop supply chain of engine remanufacturing. The paper buildings and analyses the different closed-loop supply chain models based on different recovery strategies. The main conclusions of this dissertation are as followed:(1)The paper puts forward the recovery strategy that the service station and the remanufacturer both recollect the used engine. Then it builds two different models of the closed-loop supply chain based on recovery strategy: a single channel recycling model and composite channel recycling model. The paper builds the two different mathematical models and obtains non-cooperative game equilibrium and the cooperative game equilibrium. Based on comparative analysis, it comes to the conclusion that: the remanufacturer choices the different recovery strategy based on the different fixed amount of used engine recycling. The remanufacturer will choose the non-cooperation composite channel recycling when the fixed amount of used engine recycling is zero; when the fixed amount of used engine recycling isn’t zero, the remanufacturer will have three choices: the non-cooperation composite channel recycling, the cooperation composite channel recycling and the single channel recycling.(2) The paper puts forward the“sale-buyback contract”recovery strategy. The“sale-buyback contract”model has been established. Contracted with normal closed-loop supply chain model, the remanufacturer and the customer set a protocol about the return time, the remanufacturer, the service station and the customer are in good condition by this way. Based on comparative analysis with normal model. The conclusion is following: the customer will get better profit through several remanufacturing recycling, and it will promote the customer to purchase the remanufacturer engine.(3) The paper establishes and analyses the model of closed-loop supply chain with subsidy and discipline policy. There are five different models based on the different subsidy and discipline object. Based on comparative analysis with different models. The conclusion is following: The number of use engine recovery with subsidy for service station is better than the number of use engine recovery with subsidy for remanufacturer.(4) The model with public service advertising measure is established. Demand function of remanufactured engine has been deriver by establishing utility function of customer. The paper discusses the influence coefficient of advertisement propaganda which effects the expectation of customers for the quality of remanufactured engine. Some conclusions are derived. The demand is increasing with the influence coefficient increasing.
