Research On Remanufacturing Strategy Of The Closed Loop Supply Chain With Market Size Changing Under Carbon Constraints

How to reduce the carbon emissions effectively has been a worldwide concern and carbon cap-and-trade mechanism is considered as one of the most effective market mechanisms to regulate the emissions.With carbon trading pilot progressing steadily in China,we will usher in a comprehensive carbon-constrained era.Remanufacturing can not only reduce the manufacturing cost and the pollution of the environment caused by the waste produced,it can also satisfy the requirement of developing low-carbon economic and achieve win-win state of economic and environmental benefits.Therefore,as a sustainable development strategy,CLSC(closed-loop supply chain)has become the popular subject of research in recent years.On the basis of a comprehensive analysis of domestic and international literatures about CLSC research and supply chain optimization with carbon constraints,the thesis focuses on the optimal remanufacturing strategy of CLSC under the carbon constraint:(1)The two-period dynamic decision of manufacturers with constant market size and no'new products are studied.Making analysis of how remanufacturing cost,carbon price and consumers' willingness to pay influence the optimal remanufacturing strategy.The study found that when the manufacturer remanufactures some,the manufacturer will increase the quantity of remanufacturing as the carbon price increases.The higher the recycling rate of waste products,the larger the profit margin of the manufacturer,and the manufacturer will lower the price.And new product demand will be reduced.(2)When the market size is changing and no new-style products are made,how the manufacturer choose remanufacturing strategy is studied.Make analysis of how the market size,carbon price influence remanufacturing strategy.The study found that when the market size is small,manufacturers tend to choose the strategy of not completely remanufacturing and producing new products.When the market size is large,the manufacturer chooses the strategy of completely remanufacturing and producing new products.When the willingness to pay for remanufacturing products continues to increase,the major constraint on the profitability of manufacturers is the amount of waste products that can be collected in the previous period.(3)When the market size is changing and new-style products are made,how the manufacturer choose remanufacturing strategy is studied.Make analysis of how the market size,carbon price influence remanufacturing strategy.When the size of the market is small,the pricing decisions of the two periods are independent of each other.When the market forecast is large,the manufacturer chooses lower price strategy in the first period,increases the recycling quantity of waste products to enlarge the market share.But in the first period,decline in prices leads to a decrease in margins for the manufacturer,which leads to the increase of the price of remanufactured product in the second period to maximize profits.The rise in carbon prices leads to a direct reduction in the demand for new products in the first cycle and the demand for new-style products in the second period.When the carbon emission in the remanufacturing process is sufficiently small,the willingness to pay for remanufacturing is high enough,the manufacturer would produce more remanufactured products.In this thesis,we consider the changes in the market environment facing the supply chain,and the results will provide some reference for the development of remanufacturing strategy of the CLSC under the carbon price changes,in which the manufacture are responsible of collecting waste products.
