The company employs a maintenance crew to repair its machines as needed. Management wants a simulation study done to analyze what the size of the crew should be, where the crew sizes under consideration are 2 and 3. Historically, the time required by the crew to repair a machine is, as shown in the table below. Time required by a crew of size 2 (in hours) 1 1.5 2 2.5 3 Frequency 20 60 50 40 10 Time required by a crew of size 3 (in hours) 1 1.5 2 2.5 3 Frequency 30 70 40 20 20 The average cost of maintenance work per hour is $300 in a crew of 2 and $450 in a crew of 3. Management wants the crew size with the lowest average maintenance cost based on twenty simulations each (crew size of 2 and crew size or 3). A Present your forty simulations random numbers (twenty each). B. Present the equations to estimate the lowest average maintenance cost. c. Explain what sample size management should choose.
