Research On Coordination And Optimization Of Three-Level Supply Chain Considering Retailer's Capital Constraints

With the rapid development of global economic integration and global cooperation,market competition has gradually evolved into competition among supply chains.The competitive advantage of supply chain is not only reflected in the core enterprises and large enterprises,but also plays a vital role in the competitive advantage of supply chain.However,due to the expansion of production scale,enterprise transformation and technology update,some small and medium-sized enterprises in the supply chain are hard to manage due to the lack of capital,which puts pressure on the upstream and downstream enterprises in the supply chain cooperation.However,since each member of the supply chain belongs to a different enterprise,every nodal enterprise makes decisions according to local goals.In order to make the order pricing behavior consistent with the optimal strategy of the supply chain system,it is necessary to design an appropriate incentive mechanism for the decision of supply chain members.Starting from the problem of insufficient funds in the actual supply chain,it is an important subject in the supply chain contract research to study the collaborative cooperation of nodal enterprises in the supply chain and find a mutually beneficial situation for all parties of the supply chain.According to the coordination mechanism of supply chain contract,the three-level supply chain system's coordination for retailers with capital constraint is studied.Firstly,this paper summarized the literature review of different coordination contracts under decentralized supply chain and centralized supply chain.Secondly,this paper analyzed the core enterprise by the suppliers,manufacturers and capital constraints of retailers in three-level supply chain system,analyses the retailer's capital constraints distributed three-level supply chain under wholesale price contract model,the buyback contract coordination model and repurchase revenue sharing contract combination model,to explore the suppliers,manufacturers and the retailer's capital constraints under decentralized decision making retailer's pricing and ordering decision,optimal order quantity and the maximum expected revenue;Thirdly,this paper analyzes the capital centralized three-level supply chain under the restriction of wholesale price contract model,the buyback contract coordination model and repurchase revenue sharing contract combination model,to explore the optimal order quantity under centralized decision-making supply chain and the maximum expected revenue,analysis composed of suppliers,manufacturers and capital constraints retailers coordination problem of supply chain system,and the effect of supply chain coordination under different contract;Finally,through the enterprise under the background of Matlab numerical example analysis,delves into the initial capital size,bank interest rates and the repurchase price,and other parameters on the retailers' order quantity,the supply main body gains and the influence of the supply chain overall income,comparing the expectations of a decentralized supply chain and centralized supply chain benefits,and expect earnings of the supply chain as a whole.The main conclusions of this paper are as follows: decentralized supply chain cannot coordinate the supply chain with the retailer's capital constraints,but centralized supply chain can achieve the coordination of the supply chain with the retailer's capital constraints;The more initial capital,the easier it is for the supply chain to get rid of the capital constraint,and the larger the overall expected return of the supply chain;The change of bank loan interest rate has the greatest impact on the retailer.When the loan interest rate increases,the retailer's expected income first increases and then decreases.With the increase of the revenue sharing coefficient between the retailer and the manufacturer,the expected revenue of the retailer increases gradually and the expected revenue of the manufacturer increases first and then decreases.When the revenue sharing coefficient reaches a certain value,the manufacturer's expected revenue is the largest.
