Research On Inventory Strategy Of High And Low End Substitutes

Stock is an important competitive factor for companies in intense competition.The inventory of substitutes has studied the inventory management of enterprises in the competitive environment.By optimizing the ordering decision,the enterprises can help enterprises reduce the capital occupation and reduce the operating risk while ensuring the supply.This paper studies two kinds of inventory models of alternative products in single cycle from the perspectives of suppliers and retailers respectively.The main contents of this paper include the following three aspects:First of all,this paper assumes that the type of demand distribution function is known,studies the optimal order quantity problem under the unbalanced supply-demand relationship,and uses the Newsboy model to establish two kinds of product list Cycle profit and loss model,and concludes that the retailer's order quantity is only related to the retail price,the out-of-stock cost and the wholesale price.Secondly,on the basis of the previous model,the assumptions are further relaxed and a one-cycle profit and loss model without considering the out-of-stock loss is established.Through the analysis of the model,we find that under the single cycle,the retailer's optimal order quantity is related to the selling price and the wholesale price of the product itself.Finally,under the condition of considering the residual value and the loss of out-of-stock,the single-cycle inventory problem of two alternatives is researched from the perspective of suppliers and retailers,and the single-cycle general inventory model with uncertain supply and demand is established.Through the research on the above problems,it is found that when the salvage value is positive,the optimal ordering point of a single retailer is not only related to the selling price and the wholesale price of the product but also to the recovery price.Based on the newsboy model,this paper considers the influence of the substitution rate on the stock and establishes the optimal order quantity model of the retailer and the supplier under the residual value.The obtained strategy is for the supplier under the complex and changing demand market.,Retailers provide ordering strategy has practical significance.In the end,the article also considers how to encourage retailers to place more orders and use repurchase contracts to coordinate and bind suppliers under the two-tier supply chain to achieve optimal supply chain and make the whole two-level supply chain more stable.
