In normal materials management there are basically 2 basic inventory management systems, the P system and the Q system.
P system is a system wherein replenishment is done keeping the quantity constant. The period becomes the variant. In other words you fix the quantity you want the stock to dip, to trigger a requirement. As soon as the stock level is reached you replenish the stock. During a lean period the time taken to reach the level will be longer and during an active period the time taken to reach that stock could drop.This normally relates with your consumption based planning.
Q system is a system wherein replenishment is done keeping the period constant. The quantity becomes the variant. In other words you will check for the level of stock at fixed time intervals (daily, weekly, monthly etc.) compare it with the requirements on that day and trigger the procurement process for replenishment.This normally relates with your MRP.

Abstract:
To implement an integrated system of production planning and materials management, you must have a central database wherein anyone in your company can find out all there is to know about any material passing through the plant.
Everyone must use the same rules and data structures when they enter data about material details.
