Seasonal Price Fiuctuations In Raw Materials Procurement Inventory Optimization

Only by constantly improving their competitiveness and economic efficiency in the fierce market competition, enterprises can survive and develop. Modern logistics industry is the "third-party source of profit" world-wide. Procurement management and inventory control are important parts of the logistics supply chain.There is a close relationship between the procurement of raw materials management and inventory control. If procurement amount is too big, it will lead to keeping long in stock, otherwise it will cause production stagnation. However, the price of raw materials is not always the same, especially for food processing enterprises, as the raw materials are mainly agricultural products, as price is seasonal fluctuations. If a large number of procurement, you will stand the loss when the price is down. If you purchase a small amount, you lost the profit when the price up. Therefore, fluctuations in the prices of raw materials purchasing inventory research, purchase of corporate purchasing, inventory control, and increase profits, reduce inventory costs and liquidity to meet the needs of production and operation, occupy a very important significance.My main research contents are as follows:First, the paper makes a brief introduction to the theory of purchasing inventory knowledge, and classic inventory control model and purchase price change at home and abroad Inventory Model status quo. Then, the paper uses real data to fit price function changes over time, turn the procurement price fluctuations stock research, the proposed procurement inventory model. Then, the paper tests the model with the actual data of the company of XX, and analysises the sensitivity of main parameters of the model. Finally, the paper summarizes the model. It shows that the model can effectively reduce the cost of purchasing inventory.
