Question 19

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

Question 20

In the broadest sense,preventive maintenance extends back to the installation stage of equipment and facilities.

Question 21

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?

Question 22

"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) none of the choices are correct.
