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

Breakdown maintenance is _________ preventative maintenance is _____.

Preventive maintenance is generally scheduled on the basis of: I.historical records. II.predetermined number of operating hours. III.planned inspections.

Reliability-centered maintenance is based on historical data and ongoing monitoring of equipment condition.

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

Breakdown maintenance includes activities such as equipment inspection and adjustment.

The cost of replacement is not considered as part of maintenance analysis.

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

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?

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

One basis for scheduling preventive maintenance is the passage of time.

The goal of maintenance is to maintain the productive system in good working order at minimum costs.

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?

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

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 ________________.

Cost of equipment breakdown can include: I.loss of output. II.cost of idle workers. III.damage to other equipment.

"Total productive maintenance" is best described as:

The type of maintenance which is reactive in nature is:
