The standard time to produce a certain part in a worker-machine system is 9.0 min. A rush order has been received to supply 1000 units of the part within five working days (40 hours). How many worker-machine systems must be diverted from other production to satisfy this order? Each machine must be set up at the beginning of production of parts for the order, and the setup time per machine is 5.0 hours. Fraction defect rate is 5%, and worker efficiency is 100%. Availability is expected to be 98% during setup and production. How many machines and machine operators are required during the week?
