Coordination Decision In Supply Chain With Time Varying Demand And Trade Credit

In today's business world,regardless of changes in demand or technology development,"fast" is becoming more and more important,the time is more and more sensitive to the shortening of product life cycle and the introduction of new products will accelerate,making some of the products in the initial sales,such as electronic product sales,market demand showing linear with time growth trend.In the supply chain,credit payment is an effective means to alleviate the shortage of supply chain funds,and has become a common short-term financing method.In the purchase decision between enterprises,in addition to the price,quantity,quality and other traditional influencing factors,the credit payment period has been paid more and more attention.For some enterprises with poor liquidity,it may even become the decisive factor.Especially the early release,with the stage of growth,increasing the demand for new products,the purchase of retailers,financial pressure is increasing,the way of credit payment implementation gives retailers a money back time to alleviate the financial pressure,so as to encourage retailers to normal purchase to meet the sales demand,and ultimately contribute to increase sales the supplier,increase profits.The optimal decision of decentralized decision and centralized decision of supply chain system under time-varying demand and credit payment is studied,and the coordination of supply chain is discussed and verified by numerical simulation.Instead of the traditional sunk cost,the opportunity cost is used to measure the cost of capital,and the influence of successive delivery on the decision is considered.The results show that the role of credit payment under decentralized decision-making is the means of financing;the effect of credit payment under centralized decision is not only the means of financing,but also the optimal allocation of the whole capital of the supply chain.Through the coordination research of supply chain under different circumstances,the coordination strategy of revenue distribution is put forward,which can better guide enterprises to make optimal decisions in similar situations.
