maximumvoorraden

Maximumvoorraden, or maximum stock levels, refer to the upper limit of inventory that an organization allows to be held for a given item. They serve as a control mechanism to prevent overstock, reduce carrying costs, and protect against space constraints and obsolescence, while still supporting an acceptable service level.

In inventory systems, maximum stock levels are most commonly used in periodic review models, where a firm reviews stock at fixed intervals and aims to raise the inventory up to an order-up-to level. The maximum stock level (S) is typically set to cover expected demand during the remaining lead time plus the review period, plus safety stock to absorb variability. For example, if the combination of lead time and review period is three weeks and forecast demand is 500 units per week with a safety stock of 200 units, the maximum stock level might be set around 1,700 units (3 weeks × 500 = 1,500; add safety stock). When stock reaches this level, no further orders are placed until consumption reduces the on-hand amount.

In continuous review systems, where orders are triggered by a reorder point plus fixed order quantity, the explicit maximum stock level is less central but still relevant as a cap to prevent overordering; it is influenced by the order quantity, expected on-hand at order time, and delivery lead times.

Key factors in setting maximum voorraden include demand forecast accuracy, demand variability, lead times, service level targets, storage capacity, and shelf life. Mis-sizing maximum stock can lead to stockouts or excessive carrying costs, so regular review and adjustment are common in practice.
