Question 2: Consider a manufacturing facility with 28 machines. These machines, on average, after being repaired work for 180 hours and take 9 hours to repair. Each repair costs 250 TL/repair. The hourly cost of a machine being repaired (downtime cost) is 300 TL/repair. The facility operates 10 shifts/week, 8 hr/shift, and 50 weeks/year. Calculate the availability of a machine. Calculate the expected number of machines in running condition if we visit the facility at a random time (hint: recall the Little's Law approach). Calculate the total expected cost of repairs on all machines per year and the total expected cost of downtime of all machines per year.
