Supply Cahin Finance And Operation Research Under The Restrication Of Fund

Supply chain finance and operation has become an important research subject, but little studies are focus on fund restrictions, so in this paper, through related theory of knowledge learning, assume that in a single supply chain system that composed by a single retailer and a single supplier, we create fund restriction models respectively based on the wholesale price, revenue sharing and consignment contract theory model, and verified the conclusion by the corresponding numerical examples.In this paper the main conclusions are as follows:First of all, in the wholesale price contract model, when retailers face fund constraints, they can use financial services from financial institutions to obtain the optimal order, and thus the earnings of retailers and suppliers will improve; Financial institutions will provide financial services through setting interest rates, and financing interest rate is related with the rate of average return on investment market.Secondly, in the revenue sharing contract model, when retailers face fund constraints, taking internal financial service is superior to the external financial service. In internal financial service model, supply chain’s earning is higher, and the financial interest rate is lower. Financial interest rate is related with supplier default rate & retailers default rate & the average return on investment market.Thirdly, in the consignment contract model, when suppliers face fund constraints, they can use financial services from financial institutions to gain the optimal production, and thus retailers’ and suppliers’ earnings will improve; Financing interest rate is negative correlation with supplier’s own fund and positive correlation with the average return on investment market.Finally, in three models, we respectively use uniform distribution and normal distribution market demand function to verif the the model results,states that when meeting funds restriction,the enterprise use financial services will bring greater benefits for supply chain.
