Two alternative machines are being compared. Machine Ma has an average effective process time of 2.2 hours with a standard deviation of 2.2 hour. Machine M; has a shorter effective process time of 1.5 hours but a standard deviation of 3.8 hour. Do the following analysis to compare the two machines. For an arrival rate of 0.25 jobs per hour and coefficient of variation of 1, compare the two machines for cycle time and work in process units. Which machine is preferred? Explain your answer. A. B. Repeat part A if the arrival rate is increased by 20%. C. Repeat part A if the arrival rate is decreased by 20%. D. Make smart comments on all the results above. Use the results of your calculations to make your comments (that is: do not make generic comments)
