Maintenance Strategy Development Flashcards

What is the primary benefit of condition-based maintenance over time-based maintenance?

Answer: It performs maintenance based on actual equipment condition rather than arbitrary time intervals

Condition-based maintenance uses real-time or periodic condition data to determine when maintenance is needed.

What is a maintenance strategy review and how often should it be conducted?

Answer: A periodic reassessment of maintenance approaches to ensure they remain effective

Strategy reviews periodically evaluate whether current approaches are achieving desired outcomes and adjust for changing conditions.

What is the difference between corrective maintenance and emergency maintenance?

Answer: Corrective is planned repair of known defects; emergency is unplanned response to unexpected failures

Corrective maintenance addresses known defects that can be planned; emergency maintenance responds to unexpected failures requiring immediate action.

What is the concept of maintenance prevention in equipment design?

Answer: Designing equipment to minimize or eliminate the need for maintenance

Maintenance prevention involves designing equipment to be more reliable and easier to maintain, reducing lifetime maintenance burden.

How does age-related failure differ from random failure in maintenance strategy selection?

Answer: Age-related failures justify time-based replacement; random failures require condition monitoring

Age-related failures have increasing failure probability over time, making time-based replacement effective. Random failures have constant probability, making condition-based approaches necessary.

What is the purpose of a maintenance tactics library?

Answer: To provide standardized maintenance task templates for common equipment types

A maintenance tactics library contains pre-built, standardized maintenance strategies for common equipment types, enabling consistent strategy deployment.
