Production Decisions In A Hybrid Manufacturing/Remanufacturing System With Consume Preferences Under Carbon Emission Policy

With the growing environmental problem,people pay more and more attention to environmental protection.Governments have introduced a variety of carbon emission reduction policies to cope with the increasing climate problem.Manufacturing enterprises need to reduce carbon emissions and realize sustainable development.Under the carbon emissions policies,manufacturing enterprise how to adapt to the new policy and new requirement is the enterprise survival development important issues.Remanufacturing activities can effectively reduce the carbon emissions to achieve the sustainable development of the enterprise.Due to cognitive problems,however,consumer acceptance of new products and remanufacturing products is different.Enterprise according to the constraint of the external carbon emissions and consumer preferences to make manufacturing/remanufacturing production strategy,not only can maximize their own interests,also can reduce the damage of the external environment.This Thesis based on the theory and literature review of manufacturing/remanufacturing production decisions,with the consideration of carbon emission policy and consumer preferences,according to the manufacturing enterprise whether manufacturing the product for the first time,we develop a single-period profit-maximization nonlinear programming model and a two-period profit-maximization nonlinear programming model to research the impact of carbon tax mechanism,the consumer preferences on the enterprises remanufacturing decision and pricing decision.At last,Through the case analysis to verify the validity of the model.The results of this Thesis illustrate that:with the greater consumer’s preference for remanufacturing products,the enterprise will be more positive to conduct remanufacturing,and the profit will be greater as well;The enterprises manufacturing/remanufacturing decision and pricing decision is related to unit carbon emissions trading price but which is not influenced by the initially allocated carbon emission quotas from government.When the trading price of unit carbon emissions within a certain range increases,the enterprise will reduce new product production level,at the same time increase the remanufacturing production levels.But when the trading price of unit carbon emissions increases to a certain extent,remanufacturing production levels may also be reduced.When the trading price of unit carbon emissions within a certain range increases,the profit will decrease,then,when the trading price of unit carbon emissions increases to a certain extent,the profit will increase;When carbon tax within a certain range increases,the enterprise will reduce new product production levels,at the same time increase the remanufacturing production levels.But when carbon tax increases to a certain extent,remanufacturing production levels may also be reduced.Profit will reduce with the increase of carbon tax.
