Coal, Purchased Coke Inventory Management Research On Maanshan Iron Company

The steel industry is one of the world’s most important manufacturing，is animportant indicator for measuring a country’s level of industrialization and occupiesan important position in the national economy of a country. But for now, China’s steelindustry is facing a severe challenges. International, coal and coke prices continue torise, resulting in the high cost of iron and steel enterprises, Domestic perspective, thecompany’s internal management unreasonable restricts growth in the profits of thecompany itself, these have a serious impact on the development of the company.Meanwhile, in order to prevent coal,coke and other raw material and fuel pricescontinue to rise, the company has a lot of hoarding, which also resulted in the portsand internal coal and other raw materials inventories rose sharply, a huge amount ofinventory and bring great risk to the company.In the above background, this paper ragard Maanshan Iron and Steel Company asthe research object, analysis of the problems the Maanshan Iron and Steel Companycoal and puechased coke inventory, focus on exploring the coal in the presenceproblems of several key aspects of the supply, transportation and inventory andanalyze its causes and draw the following reasons, including unreasonable price ofcoal, inaccurate demand forecasts, the ratio of unreasonable and inventory controlstrategy unscientific. For purchased coke, there are some problems in the inventory,procurement cycle and safety stock settings. On this basis, this paper establish manyvarieties of coal ratio model and multi-species the coal inventory control model, andeach example is used to verify its effectiveness. For the following additional ofCoking coal blending the resulting coke production can not meet the Maanshan Ironand Steel Company ironmaking demand, company need to purchase the part of thecoke, this paper use firstly the scientific forecasting methods to predict the totalannual demand of coke, thus get demand of outsourcing coke, and then construct thepurchased coke inventory optimization model and analysis of economid benefits, theresult is greatly optimize inventory costs.This research work provide a scientific basis for the many varieties of coalinventory management, Maanshan Iron and Steel Company, aslo optimize purchasedcoke inventory, and save a lot of money. This paper has a broad application prospectsin Maanshan Iron&Steel Company’s management level and profits increased.
