Research On Manufacturing/remanufacturing Production Decisions With Carbon Emission And Capital Constraints Considered

Since the second industrial revolution,the consumption of fossil fuels has increased,and annual C02 emissions have increased year by year,especially after the 21st century.People are gradually aware of the seriousness of a large number of greenhouse gas emissions,began to develop a variety of carbon emission reduction mechanism in order to achieve the purpose of carbon reduction.Manufacturing industry as industrial enterprises inside the higher C02 emissions of one of the industries,shoulder the pressure of carbon emissions is self-evident.Many scholars at home and abroad have studied production decisions under carbon emission reduction considerations,but these studies only take into account production decisions in different carbon emissions scenarios,without taking into account the need for carbon emissions to their own capital flows,How to make a decision.Some domestic scholars have considered the financial factors in the joint decision-making of supply chain manufacturers and manufacturers,but they do not take into account the impact of carbon emissions on production decisions.Under the circumstance of carbon emissions and capital constraints,this paper studies the influences of carbon taxes,initial capital,financing rates,new product recovery rates,consumer acceptance of remanufactured products,and downgrading rates of recycled products on Product production,profits,carbon emissions.Firstly,based on the research ideas and framework,the existing literatures are studied from three aspects:production decision-making of recycling and demand uncertainty,manufacturing decision-making of carbon production,and manufacturing decision-making.On this basis,the main influencing factors of production decision-making under the condition of carbon emission and financial restraint are summarized,and the analysis is given to provide theoretical support for the later research.Secondly,a decision-making model for manufacturing/remanufacturing is established under the three circumstances of carbon tax policy,carbon cap trade and without any restrictions on carbon emissions.Through the model solution,the impact of carbon tax and unit price of carbon emissions on new products and remanufactured products,expected profits and carbon emissions was analyzed.Thirdly,a production decision-making model of financing under the constraint of initial capital and financing is established.The research results show that the optimal production of new products and remanufactured products and expected profits increase with the initial capital increase,With the increase of the initial capital,the increase of the initial profit brought by the increase of the initial capital of the unit gradually decreases.When the manufacturer has the financial constraint and financing,if the financing interest rate is low,the manufacturer chooses to finance.At this moment,the optimal yield of the new product and the remanufactured product and expected profit are higher than those of financial constraints.If the financing interest rate is relatively high,Financing costs are too high and the manufacturers no longer finance.Lastly,the manufacturing/remanufacturing production decision-making models are established under deterministic demand with considering the capital constraint.and then considering production decision capital constraints and financing,new products,remanufactured goods,expected profits and carbon emissions are researched and compared under two cases;Finally,the influences are given through a case study of the remanufacturing rate,consumer preferences,the unit carbon emission tax and the downgrade rate of the recovered products on the optimal yield,the expected profit and the carbon emission.The results show that,considering the financial factors,whether the recovery rate is sufficient in different circumstances and the threshold is different,under the capital constraints,the higher the recovery rate as the better;With the increase of consumer preferences,the remanufacturing products produced by the manufacturer increases,the production of new products decreases,and the expected profits increases and the reduction of carbon emissions;The increase in carbon taxes will reduce the production of new products and increase the production of remanufacturers.However,when the carbon tax is too high,the production of remanufacturers will gradually decrease.The impact of the downgrade rate on corporate production decisions is just the opposite of consumer preferences.
