Inventory Management Of WK Company Under Non-stationary Stochastic Demand

Economic globalization has driven the rapid development of cross-border e-commerce.More and more small and medium-sized enterprises have chosen to expand their business overseas,and the demand for overseas warehouses is also growing.Overseas warehouses play a significant role in reducing cross-border logistics costs and improving the experience of overseas users,which in turn will cause a series of problems in inventory control:such as product backlog,product outages,high inventory cost etc.How to solve these problems is the focus of all companies.This dissertation takes Company WK as an example to conduct a series of studies on the problems it encounters in inventory management.This dissertation first locates the main problems encountered by Company WK's overseas market:The main products TOP out of stock problem,the main product TOK backlog problem,the problem of high inventory cost of the product to be repaired.The reasons for these inventory management problems are analyzed and corresponding solutions are given.In view of the above problems,the fourth chapter of this dissertation proposes a demand forecasting method and ordering strategy for WK products.This chapter first analyzes the current situation of WK's current product demand forecasting,and uses SPSS statistical analysis software to forecast the company's products.Then builds the WK product ordering strategy model,which determines the ordering point at the beginning of the planning period,and then determines the order quantity of each order point according to the realization of the demand.The model considers the case of missing orders for out-of-stocks,with the goal of fixed order cost,variable ordering cost,inventory holding cost,out-of-stock cost,and consumer retention cost.Finally,the product ordering strategy model proposed in this dissertation is applied,and the ordering strategies of WK company's product TOP and product TOK are given respectively.The fifth chapter analyzes the improvement effect of WK company's demand forecasting,and carries on the economic analysis of the ordering strategy improvement.By comparing the product inventory situation and the total system cost before and after the improvement,the effectiveness of the improvement measures proposed in this dissertation is proved.Finally,Several suggestions for improvement were made for the inventory management problem.The solution proposed in this dissertation for the inventory management problem of WK company helps WK Company to achieve more reasonable demand forecasting,formulate a more scientific ordering strategy,and finally help WK Company to solve the problem of product out of stock or backlog caused by inaccurate demand forecasting and unscientific ordering strategy.The solution also helps the company reduce inventory levels and reduce total system costs.The solution and ideas of this dissertation also have certain reference value for domestic similar enterprises.In this dissertation,there are 20 figures,24 tables,and 58 references.
