[Solved] Every time a machine breaks down at the Dynaco Manufacturing Company, either 1, 2, or 3 hours are required to fix it, according to the following

Question: Every time a machine breaks down at the Dynaco Manufacturing Company, either 1, 2, or 3 hours are required to fix it, according to the following probability distribution:

Repair Time (Hours) Probability

1 .30
2 .50
3 .20

Total 1.00

  1. Simulate the repair time for 20 weeks and then compute the average weekly repair time.
  2. If the random numbers that are used to simulate break downs per week are also used to simulate repair time per break down, will the results be affected in anyway? Explain.
  3. If it cost $50 per hour to repair a machine when it breaks down (including lost productivity), determine the average weekly breakdown cost.
  4. The Dynaco Company is considering a preventative maintenance that would alter the probabilities of the machine break downs per week as shown in the following table:

Machine Break downs per week Probability

0 .20
1 .30
2 .20
3 .15
4 .10
5 .05

Total 1.00

The weekly cost of the preventative maintenance program is $150. Using simulation, determine whether the company should institute the preventative maintenance program.
