1. The goal of maintenance is to minimize cost.
2. The goal of maintenance is to maintain the productive system in good working order while
minimizing or eliminating the cost of preventive maintenance.
3. Breakdown maintenance includes activities such as equipment inspection and adjustment.
Chapter 14S – Maintenance
4. Degree of technology is a factor affecting the decision of how much preventive
maintenance is desirable.
5. Breakdown maintenance is best performed on a regularly scheduled basis.
6. One basis for scheduling preventive maintenance is passage of time.
Chapter 14S – Maintenance
7. Ideally, preventive maintenance will be performed before a breakdown or failure.
8. In the broadest sense, preventive maintenance extends back to the installation stage of
equipment and facilities.
9. Pareto analysis (using the 80/20 rule) is one method of determining when preventive
maintenance activities should be performed.
Chapter 14S – Maintenance
10. In the area of maintenance, the Pareto phenomenon is reflected in the fact that, regardless
of problem classification, all equipment will justify about the same expense.
11. Proactive maintenance is periodic.
12. It is best to replace a failing piece of equipment with one that will have identical
capabilities as the equipment being replaced since we are already familiar with that machine.
Chapter 14S – Maintenance
13. Cutting preventive maintenance in half will probably double the number of breakdowns.
14. If one operator performing preventive maintenance requires two hours to complete the
job, then two operators working together should complete the preventive maintenance in one
hour.
15. Maintenance activities are often organized into the two groups:
Chapter 14S – Maintenance
16. Breakdown maintenance is _____________; preventative maintenance is _________.
Chapter 14S – Maintenance
17. The goal of maintenance is to maintain the productive system in good working order
while minimizing:
18. ___________ is most closely associated with breakdown maintenance.
Chapter 14S – Maintenance
19. Factors affecting the decision of how much preventive maintenance is desirable typically
include all of the following except:
20. Cost of equipment breakdown doesn’t include:
Chapter 14S – Maintenance
21. The optimum amount of preventive maintenance is where:
22. The type of maintenance which is periodic in nature is:
Chapter 14S – Maintenance
23. Preventive maintenance is generally scheduled on the basis of:
24. Ideally, preventive maintenance will be performed:
Chapter 14S – Maintenance
25. Attempting to determine when preventive maintenance activities should be performed is
called:
26. “Total productive maintenance” is best described as:
Chapter 14S – Maintenance
27. In the broadest sense, equipment and facilities preventive maintenance extends back to
the:
28. The major approaches used in plans to deal with breakdowns include all of the following
except:
Chapter 14S – Maintenance
29. In the area of maintenance, the Pareto phenomenon is reflected in the fact that:
30. Reactive maintenance is _____________ maintenance.
Chapter 14S – Maintenance
31. The total maintenance curve (preventive maintenance cost plus breakdown and repair
cost):
Chapter 14S – Maintenance
32. The frequency of breakdown of a piece of equipment per month is shown in the table. The
cost of a breakdown is $1,000 and the cost of preventive maintenance is $2,000 per month.
Assume that the equipment breakdown can be avoided if preventive maintenance is
performed. Should the manager use preventive maintenance, or would it be better to fix the
equipment when it breaks down?
Chapter 14S – Maintenance
33. The average time before breakdown of a machine is normally distributed and has a mean
of 7 weeks and a standard deviation of 1.5 weeks. If breakdown cost averages $2,500 and
preventive maintenance costs $500, what is the optimal preventive maintenance interval?
An optimal maintenance interval is approximately every 5½ weeks.
34. The average time before breakdown of a machine is normally distributed and has a mean
of 9 weeks and a standard deviation of 1.5 weeks. If breakdown cost averages $1,500 and
preventive maintenance costs $500, what is the optimal preventive maintenance interval?
Chapter 14S – Maintenance
35. The average time before breakdown of a machine is normally distributed and has a mean
of 18 weeks and a standard deviation of 3 weeks. If breakdown cost averages $2,000 and
preventive maintenance costs $1,400, what is the optimal preventive maintenance interval?
36. Which of the following is the primary consideration with regard to preventative
maintenance?
Chapter 14S – Maintenance
37. Which of the following would not improve the performance of a breakdown program?
38. Breakdown programs often are prioritized such that some equipment gets a lot of attention
and others get very little. This typically reflects the fact that breakdowns are consistent with
__________.
