Restockfrekvens

Restockfrekvens, or restock frequency, is a term used in inventory management to describe how often stock is replenished within a given period. It can be expressed as the number of replenishment events per time unit or as the average time between restocks. The metric helps organizations understand how often they must place orders or receive deliveries to maintain desired service levels.

In quantitative terms, if the demand rate is D units per period and the fixed replenishment quantity is Q units, the restockfrekvens can be described as follows: replenishments per period = D / Q, and the average time between restocks T = Q / D. For example, with a weekly demand of 500 units and an order quantity of 1250 units, replenishments per week would be 0.4, implying an average restock interval of 2.5 weeks. This relationship ties restockfrekvens directly to order quantity and demand.

Restockfrekvens is relevant in different inventory systems. In a continuous review (Q-system), restocks occur whenever inventory position hits a reorder point, and the frequency depends on Q and D. In a periodic review (P-system), replenishment happens at fixed intervals, so the restockfrekvens is determined by the review cycle. Lead time, demand variability, and safety stock influence the practical frequency alongside supplier constraints and batch sizes.

Importance and trade-offs: increasing the restockfrekvens lowers the risk of stockouts and improves service levels but can raise ordering and handling costs. Decreasing frequency can reduce ordering costs and supplier interactions but may increase carrying costs and the likelihood of stockouts between orders. Proper management of restockfrekvens supports balanced inventory levels, cost efficiency, and customer satisfaction.
