Research on Inventory Control of Colliery Material

摘要

System dynamics model of colliery material inventory control, containing chief storage and mine supermarket, was created in this paper. Controllable variables in the model includes chief storage's inventory, mine supermarket's expect inventory and mine supermarket's receive delay time. After adjusting and coordinating them, outcome of simulation, analysis and comparison of the effect variables bring to the colliery material inventory control, value range and best point of the variables will be available, and the optimized scheme contains fulfilling producing material demand, reducing chief storage's inventory and total inventory of material, decrease colliery material inventory cost will be feasible.
