inventory system governed by a continuous review (Q,r) policy: (i) when the inventory position (stock on hand plus stock on order minus backorders) reaches the reorder point r, an order is placed with the batch size Q; (ii) the storage space is capacitated, and unmet demands are partially backordered
; and (iii) there is a "free waiting time" during which there is no backorder cost for the model.
