In the broadest sense, equipment and facilities preventive maintenance extends back to the:

"Total productive maintenance" is best described as:

The type of maintenance which is periodic in nature is:

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.

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

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.

Reactive maintenance is _____________ maintenance.

Ideally, preventive maintenance will be performed before a breakdown or failure.

Cutting preventive maintenance in half will probably double the number of breakdowns.

___________ is most closely associated with breakdown maintenance.

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 __________.

Breakdown maintenance is _____________; preventative maintenance is _________.

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.

The goal of maintenance is to minimize cost.

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?

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