Research on inventory control model and algorithm for commercial coal logistics park

Coal logistics park has been an important infrastructure for coal logistics, its inventory management is important, but difficulty. The paper analysis the feasibility of logistics park transforming service pattern to business pattern, studies the importance of inventory control. By analyzing the composition of inventory, it creates a new inventory control model with a number of parameters containing coal washing rate and cycle. The result shows that new inventory control model is the extension of classical Economic Order Quantity Model, the order cycle is the monotonic increasing function of product for washing rate and raw coal achieve frequency, and the order quantity is the monotonous decrease function of product for washing rate and raw coal achieve frequency. They are all related to the raw coal washing rate, not related to washing cycle.
