Definition

A continuous‑review inventory model that triggers fixed‑quantity orders of size Q whenever the inventory position falls to a reorder point R; it balances ordering cost (favoring larger Q) and holding cost (favoring smaller Q) while R is typically set to protect against lead‑time demand variability.
