Concerning such a situation, we study in this paper a single item partially
backordered 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.

Decision Variables: [XP.sub.it]: Number of items 'i' to be produced during the period 't' [XINV.sub.it]: Number of items 'i' carried as inventory at the end of period 't' [XBO.sub.it]: Number of items 'i' that will be
backordered from period 't' [YS.sub.it]: Binary variable for setup of the resource for item 'i' during the period 't' = 0 (if there is no setup required), 1 otherwise Parameters: [CP.sub.it]: Unit cost of producing item 'i' in period 't' [CS.sub.it]: Unit cost of setup, for item 'i' in period 't' [CINV.sub.it]: Unit cost of holding inventory of item 'i' for 1 period.
