Research On Inventory Control Optimization Of A Company’s Online Channel Under Non-stationary Stochastic Demand

In the fierce environment of market competition,inventory is a contradiction for air conditioning industry.On the one hand,keeping inventory can meet the needs of consumers quickly.On the other hand,excessive inventory will also occupy enterprise funds and increase inventory costs.In addition,with the progress of Internet technology and the development of e-commerce,air conditioning enterprises are also developing online business constantly.In this case,company A,as the mainstream air-conditioning manufacturer in China,also conforms to the current development trend and established a huge online sales system.But the effect of current online channel inventory control of A company is not ideal.Not only maintain a high level of inventory,but also maintain a high level of shortage.In the long run,it will inevitably cause great losses to the enterprise.So,how to improve the online channel inventory control is a problem to be solved by A company.In this paper,make the actual situation of A company as the background.First of all,sort out overview of A company and its online channel,analyze the demand characteristics of air conditioning products of online channel,and select the appropriate demand forecasting method to forecast its demand.At the same time,this paper analyzes and summarizes the method of demand forecasting and inventory control and the effect of the method adopted by online channel of A company currently,finds out the problems existing in inventory control,and analyzes the reasons.Secondly,according to the characteristics of non-stationary random demand of air-conditioning products in company A’s online channels,the static and dynamic inventory control model considering shortage cost is improved.Considering the demand characteristics of air-conditioning products in low and peak seasons,the proportion of lost orders and shortage cost are adjusted,and the composition of shortage cost is analyzed,Based on this,an inventory control model with non-stationary stochastic demand is constructed,which is in line with the actual situation of company A,and the model is solved.Finally,the effect of inventory control before and after is analyzed from two aspects of inventory level and out of stock level.The results show that the static dynamic two-stage inventory control model constructed in this paper can effectively reduce the inventory level and out of stock level,which proves the effectiveness of the model in solving the problem of online channel inventory control of A company.At the same time,this paper makes a sensitivity analysis on the coefficient of loss cost of out of stock in the model,and puts forward corresponding management suggestions for enterprises according to the results of sensitivity analysis.There are 10 figures,11 tables and 50 references in this paper.
