Dr. Jack is in charge of the Blood Bank at the local hospital. Blood is collected in the regional blood center 200 miles away and is delivered to the hospital by airplane. Dr. Jack reviews the inventory and places order every Monday morning for delivery the following Monday morning. If demand begins to exceed supply, surgeons postpone non-urgent procedures, in which case blood is back ordered.
