Research On Supply Chain Optimization Based On Trade Credit Under Different Demand Background

With the rapid development of society,the product market is increasingly changing and the competition is becoming more and more intensifying,Increasing customers' demand for personalization and enrichment of products and service.Trade credits has become the first key element to winning competition besides cost,price,quality and service.With the development of economic globalization,the competitive relationship between enterprises is mainly manifested in the competition between the supply chain and the supply chain where the company is located.A large number of studies have shown that trade credit can effectively reduce transaction costs among members of the supply chain and is considered as one of the main sources of short-term financing of member companies in the supply chain.As a strategic tool for enterprises to improve efficiency and maintain their core competitiveness,trade credit can effectively help enterprises achieve a virtuous cycle of logistics,information flow and capital flow,thereby strengthening the overall competitiveness of enterprises.However,powerful and well-funded suppliers,as upstream companies in the supply chain,in order to publicize their own corporate brand,let the public know their product brand,Usually,advertisements will be launched through online and offline channels,at the same time,it provides a certain commercial credit payment term for downstream businesses for motivating more retailers to order products,and then expand the market demand of products.In addition,as a downstream company in the supply chain,retailers,while enjoying the commercial credit concessions offered by suppliers,will also implement certain sales efforts to expand product sales and achieve overall improvement in their overall benefits.Based on the above background information,this paper considers a two-tier supply chain system consisting of a single supplier and a single retailer that produces a single product.Firstly,it builds a business-based credit based on the general market demand and considering the influence of the supplier's advertising efforts to influence demand.The EOQ model and correspondingly analyzed the supply chain optimization decision under the decentralized decision model and the centralized decision model,and solved the corresponding optimal decision and the optimal annual average total profit.Besides,It also analyzes the impact of advertising efforts on order period and annual average profit.as well as the impact of the trade credit payment period on the optimal decision;verifying the optimal ordering cycle and the optimal annual average of the members and systems of the supply chain considering the factors of advertising efforts.Total profit has been optimized.Secondly,under the background that business credit payment term and sales effort level affect demand together,considering the possibility of default risk of retailers,the supply chain optimization model under decentralized decision-making model and centralized decisionmaking model was established respectively,and the optimum was obtained.The decision and the expression of the optimal annual average total profit were also demonstrated by numerical analysis and sensitivity analysis of different parameters.Finally,the research content of this paper is summarized and some practical inspirations are given.The future research direction is elaborated.
