Research On Supply Chain Coordination Mechanism Considering Deferred Payment Under Demand Uncertainty

Trade credit has been applied to trade goods or services between the buyer and the seller in the form of deferred payment or payment in advance.There are two forms of trade credit tactics:delay in payment or prepayment.Deferred payment has become a common phenomenon in the commercial activity,and because the delay in payment has a very important practical significance,more and more current research about the subject has been studied.But most research is that a supplier by giving retailers deferred payment can increase sales and expand market share.Actually,retailers can also follow the supplier by offering consumers deferred payment to expand sales,occupy the market and establish a good corporate image.This article is to use the background of retailers providing the deferred payment to consumers,to carry out in-depth research.In the postponement of delayed payment of commercial credit strategy and with the economic globalization,product diversification and technological progress in many industries,consumer demand has become increasingly uncertain.Therefore,in the uncertain market environment,how to develop the relevant business credit strategy for the enterprise,and how to coordinate the supply chain are the main problems to be studied in this paper.The paper divides the demand uncertainty into two kinds of situations:one is the market demand of the disturbance and the other is the stochastic demand of the commercial credit competition.First,this paper reviews the related literatures of deferred payment,demand uncertainty and supply chain competition.Secondly,it discusses the change of decision-making of members in supply chain before and after the demand disturbance,and analyzes the coordination effect of quantity discount contract on supply chain.Considering the uncertainty model of commercial credit competition,the optimal decision of supplier and retailer in centralized decision supply chain and decentralized decision supply chain are studied,and the coordination effect of buyback contract on supply chain is analyzed.Through the study,it is found that the more accurate the commercial credit,the higher the optimal order quantity of the retailer.With the increasing of the commercial credit competition,the optimal order quantity of the retailer who provides the longer extended payment credit period is greater than that of providing the shorter credit.The retailer's retail price will increase and the retailer's deferred payment credit period will decrease.As the demand disturbance is small,the supplier will not change the production plan,but when the demand is disturbed,the retailer's retail price will increase.When the demand disturbance is much larger,the supplier will increase or decrease the production accordingly.
