Research On Two-Level Supply Chain Stock Transfer Strategy Considering Transportation Uncertainty

Supply uncertainty is the actual problem faced by many companies,and the impact on the supply chain is increasing,which brings risks to the operation of the supply chain.Transportation uncertainty is an important situation in supply uncertainty.Therefore,in order to avoid and solve the adverse effects brought by supply uncertainty,this paper takes the fresh agricultural product industry as an example,and focuses on the inventory transfer strategy adopted by enterprises when they face the transportation uncertainty environment and their impact on the profit of all members of the supply chain.In the context of transportation uncertainty,this paper first constructs a secondary supply chain benchmark model consisting of one supplier and two retailers in VMI and RMI modes,and discusses the supply chain with no inventory transfer under two modes.Optimal decision making.Then,in both modes,one-way inventory transfer and two-way inventory transfer are introduced,which are compared with the non-stock transfer.The two models are responsible for the implementation of inventory transfer,management and processing of inventory by suppliers and retailers.After using MATLAB for data analysis,we found that in the one-way transport strategy of VMI mode,transshipment does not necessarily increase the profit of the retailer while increasing the expected profit of the supplier,and the retailer expects the profit and the actual supplier.The amount of input is related;in two-way transshipment,the supplier's profit will increase as the cost of the supplier decreases.In the one-way transfer strategy in RMI mode,the supplier expects the profit to be always lower than the case of no-stock transfer.In addition,the ordering decision of the retailer accepting the transhipment is constrained by the wholesale price of the supplier and the portability of the product,and the expected profit will decrease as the order quantity of the product increases.In two-way transshipment,the quantity of retailers implementing inventory transshipment is positively correlated with the retailer's order quantity;when the market price is lower,the expected profit of retailers and suppliers will decrease as the retailer's product order quantity decreases.
