Sometimes companies procure a lot of goods and often the goods ordered are not in accordance with the request self storage nearby. Because the production process cannot be delayed, the availability of supplies will help companies that lack material due to the return of some raw materials because they are not on demand. The company can predict when raw materials will rise and when the raw materials needed for the price will go down. When the price of raw materials in the market decreases, companies can buy large quantities of raw materials. These raw materials can be used as inventory where when the company needs no more buying. Existing inventory on 自存倉 can also prevent inflation or increase in raw material prices. So when raw materials experience rapid increases, companies are no longer bothered to buy raw materials.
Sometimes the production process is constrained by the lack of raw materials in the market while the demand for consumers will continue to increase. Companies can buy raw materials that are needed but the price is much more expensive. When the selling price of goods is unable to be raised and the price of raw materials is increasing, inevitably the company continues to produce but with very little profit. As the right solution, when the price of raw materials goes down the company can buy a lot of raw materials for the production process and also to be stored in the warehouse. The process of storing raw materials is intended to prevent the occurrence of raw material vacancies during certain seasons. Management inventory is needed by companies and can be done in various ways. One way to do this is by analyzing the value of the inventory. In this analysis, inventory can be divided into investment values ??that have been used in that period. Inventory can be divided into three classes, for example class A, B, and class C which are based on inventory value. The value in the classification is the volume of inventory needed in one period or in one year then multiplied by the price per unit.
