Research On Supply Chain Coordination With Uncertain Output Under Advance Payment Financing

Nowadays,the market environment is becoming more and more complex,and the actual output of many industries becomes very uncertain due to external and internal factors.The uncertainty of output may make the supply chain supply unable to meet market demand and bring the risk of out of stock to the supply chain.At the same time,the difficulty of financing for SMEs is unresolved,and the break of the capital chain will seriously affect the operational efficiency of the supply chain.Therefore,how to solve the problems caused by output uncertainty and ensure the stability of supply chain capital flow has become a difficult problem for enterprises to solve.In addition,companies in the supply chain only consider their own income problems,which inevitably leads to “double marginal effects”,which damage the overall income of the supply chain.In addition,in today's megatrends of consumption upgrades,competition among supply chains has gradually shifted from a price dimension to a quality dimension.However,existing coordination studies of output-indetermined supply chains rarely consider suppliers' financial constraints and product quality levels.Therefore,in the case of uncertain output,this paper studies the production and coordination of supply chain financing with a two-level supply chain consisting of a single resource-constrained supplier and a single retailer.On this basis,the impact of considering the product quality level on the supply chain is further analyzed.Under the condition of fixed demand and random demand,the optimal decision model of suppliers under prepayment financing is studied,and the reasonable value range of prepayment financing interest rate is discussed.In addition,by introducing the supply chain contract,the supply chain is coordinated under the prepayment financing,and the conditions for satisfying the parameters of the contract are obtained.Finally,through numerical analysis,the influence of prepayment financing interest rate and contract parameters on the expected returns of both parties in the supply chain is discussed,and the correctness of the research conclusions is verified.Research shows that in the case of uncertain output,advance payment can solve the problem of supplier's financial constraints,but it can't make the supply chain reach coordination.At this time,the output risk sharing contract can coordinate the supply chain and make the profit distribution between inter-member;when further considering the quality level,a single output risk sharing contract cannot coordinate the supply chain,but the supply chain can achieve coordination after the introduction of the quality cost sharing mechanism.
