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) Time required by a crew of size 3 (in hours) 1 1 1.5 2 2.5 3 Frequency 30 70 60 30 10 1.5 2 2.5 3 Frequency 40 70 90 20 10 The average cost of maintenance work per hour is $1,000 in a crew of 2 and $1,200 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.
