Supply Chain Coordination With Limited Order Funds For Retailer Under Supply And Demand Uncertainty

Along with the development of global economic integration,supply chain is facing more and more problems,such as the supply uncertainty,demand uncertainty,limited funds and risk,etc.These problems affect supply chain's decision-making,increase the difficulty of the supply chain coordination.Therefore,under the condition of limited funds and control risk,the design of the supply chain coordination strategy has important practical significance.This thesis studies the supply chain coordination problem with supply and demand uncertainty,in which the retailer has limited order funds and different risk attitudes.The purpose of this thesis is to analyze the supply chain coordination mechanism of credit payment strategy combined with revenue sharing contract and buyback contract respectively.The main findings are as follows:(1)In the case of the retailer is risk neutral,the credit payment and revenue sharing contract can coordinate supply chain with supply and demand uncertainty and the retailer has limited order funds.When the supply chain is in a sate of coordination,as the wholesale price and revenue sharing ratio increase,the interest rate and order funds increase seperately,the retailer's expected profit increases,while the supplier's expected profits decreases;Compared with the situation where the supply is certain and the demand is uncertain,the wholesale price is higher or the revenue sharing ratio is lower.(2)In the case of the retailer is risk averse and CVaR criteria is used to measure risk,the credit payment and revenue sharing contract can coordinate the supply chain when the degree of risk aversion within a certain range and the contract parameters satisfy certain conditions.When the supply chain is in a sate of coordination,as the interest rate,order funds and the degree of risk aversion increase,the supplier's expected profit decreases,while the retailer's CVaR profit increases;As the interest rate and risk aversion rise,wholesale price falls.(3)In the case of retailer is risk averse and the mean-CVaR criteria is used to measure risk,the credit payment and buyback contract can coordinate the supply chain when the risk aversion degree is in a different range and the contract parameters satisfy the corresponding conditions.When the supply chain is in a sate of coordination,with the increase of interest rates,the buyback price and supplier's expected profit increase,and the retailer's expected utility decreases;With the increases of order funds,the retailer's expected utility increases,while the supplier's expected profit decreases.With the increases of risk aversion,the buyback price increases,and when the value exceeds the critical value,the buyback price no longer changes.As the weight coefficient increases,the buyback price decreases.This thesis comprehensively considers the supply and demand uncertainty,limited funds and risk factors,which is in line with the real operating environment of the supply chain.Applying internal financing,this study solves the problem of limited funds for retailers and realizes supply chain coordination,which provides an effective solution for practical decision makers.
