In a typical 7-day period, the planning department programs a machine to work for 168 hours. The machine has 7 hours a week without any work scheduled. Changeovers and set-ups take 3 hours and breakdowns average 5 hours each week. Waiting for materials to be delivered constitutes 6 hours in which the machine cannot work. When the machine is running, it averages 95% rated speed. After production, 2.5% of the parts processed are found to be defective.
