Two-stage Payment Strategy Under Carbon Trading Constraints Research On Supply Chain Inventory

Since the beginning of the new century,the economic development has also led to the problem of carbon dioxide pollution which has caused a great obstacle and threat to people’s production and life.At the same time,the selection and decision-making of supply chain inventory strategy is also a concern of the society and scholars at this stage,so how to reduce the negative impact of the development of the economy on the society is particularly important.Under the content of supply chain strategy,carry out research,carry out more in-depth discussion,adding carbon trading that constraint,considering the two phase delay payment terms at the same time,a more comprehensive analysis of the supply chain inventory problem,the enterprise and society of the government to take corresponding measures to make the common economic development and environment to present a good situation,makes the life more meaningful.Among all the enterprises in the operation of the supply chain,large amount of carbon dioxide emissions,which is a key part of the supply chain system needs to be addressed in the inventory system,it has a great influence to the whole supply chain carbon,carbon emissions inventory control problem is therefore need to be studied in the supply chain system,studies the necessity and value.This paper directs at a single manufacturer and a single retailer.It is a two-level supply chain.And the world is in a low carbon economy which has the background of the world.The carbon policy is added which is constructed with the concept of payment days numerical simulation model as a strategy of deferred payment,by analyzing the profit function,and investigates the parameters such as inventory,product quality and the carbon price can make a difference to optimal inventory,The existence and uniqueness of the optimal inventory strategy are proved.Correspondingly,integrated the calculation examples of specific enterprises,the validity of the model is tested,and sensitivity validation analysis was performed for the listed major parameters by using the mathematical tool called MATLAB software.and a series of conclusions are drawn.Under the condition of full payment and partial branch,different demand causes different strategy choice.In addition,by analyzing the production-inventory cost models under the cap-and-trade and carbon tax mechanisms,it is concluded that under the cap-and-trade mechanism which reduces the production volume of the manufacturer,the order frequency decreases and the order quantity increases.At last,the total cost is higher than that without carbon constraint.When considering the factor of carbon price,the constraint mechanism that is reasonable for the manufacturer is also obtained from the corresponding analysis.
