Research On T Company's Main Raw Material Inventory Control Strategy With Fuzzy Demand

Inventory has always been an important means of regulating supply and demand in traditional supply chain management,and is a buffer between supply and demand.However,if the inventory is too large,it will occupy the cash flow of the enterprise and generate high inventory cost.If the inventory is too small,it may be unable to meet the production and sales requirements and damage the customer service level.How to properly control inventory and inventory costs has always been an important challenge for companies.T company is an architectural coatings manufacturer.The cost of raw material procurement accounts for more than 90%of the total production cost.The current status of raw material inventory management is mainly due to high inventory,low inventory turnover,and large inventory counts,resulting in high raw material inventory costs.Compared with other T company's stocks,raw material stocks have more urgent management and control need.In this paper,through the description and analysis of the current situation of raw material inventory of T company,the problems of the company's raw material inventory are found out.The reasons for the company's raw material inventory problems are:no scientific classification management,and lack of reasonable raw material procurement strategy.This paper firstly describes and analyzes the current situation of raw material inventory of T company,and finds that the company's raw material inventory management has three main problem,high total inventory levels,difficult to control raw material purchases,and confusing location management,resulting huge waste of storage space management.Then,based on the analysis of T company's raw material inventory management issues,the reasons for the company's raw material inventory problems are lack of scientific inventory classification,location management methods,and lack of effective raw material procurement strategies.In view of the analysis of the causes of the problems of raw materials inventory of T company,this paper proposes a solution to the problem of raw material inventory management of T company:(1)Firstly,the ABC classification method is used to scientifically and rationally classify raw material inventory,find out the main raw materials which most significantly impact on raw material inventory cost,and matched it with the ordering strategy of continuous inventory(Q,r);(2)Then,based on the actual situation of Company T and the research of previous researchers,this paper use fuzzy random number theory to describe the uncertain demand of raw materials of Class A,and discuss the total inventory cost function model with two factors:price discount and fixed order cost changing under the(Q,r)strategy;(3)Finally,the total cost function is analyzed to give the total cost.Subsequently,this paper selected 10 kinds of raw materials stocks to verify the proposed solutions and models by using the data of raw materials management of T company.Then it decide the optimal order quantity and reorder point of these 10 raw materials,and calculate the total inventory cost before and after optimization using the inventory model proposed in this paper.The data results show that the application of the method model saves the total cost of raw material inventory management,reduces the average inventory level of the enterprise,and has practical significance for T company s raw material inventory optimization control.At the end of the paper,the real data of T company's 10 main raw materials are used to verify and evaluate the proposed scheme and model.The data shows that the application of the method model saves the total cost of raw material inventory management and reduces the average inventory level of enterprises,so as to verify that it has practical significance for T company's raw material inventory optimization control.
