Question 11

Breakdown maintenance takes the form of scheduled periodic maintenance.

Question 12

In the area of maintenance,there is a trade-off between the cost of preventive maintenance and breakdown (emergency)maintenance.

Question 13

Predictive maintenance is a major part of reliability-centered maintenance.

Question 14

The degree of technology involved is a factor affecting the decision of how much preventive maintenance is desirable.

Question 15

Planned periodic inspections is one method of determining when preventive maintenance activities should be performed.

Question 16

Which of the following is most closely associated with breakdown maintenance?

A)Equipment adjustments
B)Equipment cleaning
C)Equipment inspection
D)Repair of broken parts
E)Replacement of worn parts

Question 17

Maintenance activities are often organized into the two groups: buildings and grounds,and equipment maintenance.

Question 18

Maintenance activities are often organized into the two groups:

A)breakdown maintenance and preventive maintenance.
B)breakdown maintenance and predictive maintenance.
C)preventive maintenance and predictive maintenance.
D)equipment maintenance and breakdown maintenance.
E)equipment maintenance and buildings maintenance.

Question 19

Factors affecting the decision of how much preventive maintenance is desirable typically include all of the following EXCEPT:

A)age of equipment.
B)type of product.
C)degree of technology.
D)type of production process.
E)condition of facilities and equipment.

Question 20

The goal of maintenance is to maintain the productive system in good working order while minimizing:

A)total preventive maintenance costs.
B)total breakdown maintenance costs.
C)total maintenance costs.
D)the difference between preventive and breakdown costs.
E)the ratio of breakdown to preventive maintenance costs.

Question 21

When breakdowns become frequent and/or costly,managers are faced with a trade-off decision between the cost of continued maintenance and the cost of ________________.

A)passage of time
B)preventive maintenance
C)breakdowns
D)replacement
E)reliability

Question 22

Ideally,preventive maintenance will be performed:

A)after a planned inspection.
B)after the passage of a specified period of time.
C)after a predetermined number of operating hours.
D)just prior to the start of the workday.
E)just prior to a breakdown.

Question 23

"Total productive maintenance" is best described as:

A)avoiding all breakdown maintenance.
B)doing a great deal of preventative maintenance to try to avoid breakdown maintenance.
C)having workers that operate equipment responsible for performing maintenance.
D)extending preventative maintenance back to design.
E)simultaneously changing all components that are subject to a breakdown.

Question 24

The frequency of breakdown of a piece of equipment is 2.55 breakdowns per month.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?

Question 25

The average time before breakdown of a machine is normally distributed and has a mean of 11 weeks and a standard deviation of 2.5 weeks.If breakdown cost averages $2,500 and preventive maintenance costs $500,what is the optimal preventive maintenance interval?

Question 26

A)breakdown maintenance.
B)predictive maintenance.
C)preventive maintenance.
D)total productive maintenance.
E)reliability-centered maintenance.

Question 27

Reliability-centered maintenance is an approach based on:

A)dealing with breakdowns after they occur.
B)reducing the effect of each major cause of failure.
C)increasing frequency of preventive maintenance.
D)predictions based on historical data.
E)routine planned inspections.
