Two machining operations A ( 3 minutes per part) and B ( 10 minutes per part) are performed sequentially to manufacture a part. Machines A and B produce 5% and 6% defective items, respectively. The factory operates 9 hours each day with one hour off for lunch break, 5 days per week, 4.2 weeks per month. Every day each machine needs 0.30 hours for being set up. Find the number of machines for each type (A and B ) if we need to handle a demand of 10,000 items per year? Use a machine-down factor equal to 15% for each machine
