In inventory theory, the (Q,r) model is used to determine optimal ordering policies. It is a class of inventory control models that generalize and combine elements of both the Economic Order Quantity (EOQ) model and the base stock model. The (Q,r) model addresses the question of when and how much to order, aiming to minimize total inventory costs, which typically include ordering costs, holding costs, and shortage costs.
