opslagniveau

Op slagniveau, or stock level, is a term used in inventory management to describe the quantity of goods currently stored for a specific item. It indicates how much inventory is physically available to fulfill orders at a given moment and is typically tracked in enterprise resource planning (ERP) or inventory systems. Depending on the context, opslagniveau may refer to on-hand stock or to available stock, which excludes quantities already allocated to orders or reservations.

The concept is central to replenishment and production planning. It informs when to reorder, how much to reorder, and how to balance carrying costs against service level. In practice, operators use target or limit levels such as a reorder point and safety stock. A common rule is ROP = demand during lead time + safety stock. Safety stock mitigates uncertainty in demand and lead time, and is set according to the desired service level, variability, and supplier performance.

Other related notions include base stock level, minimum and maximum stock levels, and simple systems like two-bin or Kanban that use predefined opslagniveau as a triggering signal. Periodic stocktaking and perpetual inventory enable accurate measurement of opslagniveau and help detect discrepancies.

In performance terms, opslagniveau affects service levels, stock turn, and carrying costs. Too low a level increases the risk of stockouts; too high ties up capital and can lead to obsolescence. For example, if daily usage is 50 units and lead time is 7 days, demand during lead time is 350 units; with a safety stock of 50, the suggested reorder point is 400 units, with a target opslagniveau around 450 depending on context.
