Asset Management Asset Maintenance and Reliability 3

Question 1

What is 'deferred maintenance' in asset management?

Accepted Answer

Maintenance that has been postponed beyond its originally scheduled date

Answer

Deferred maintenance refers to maintenance tasks that have been delayed or postponed past their recommended schedule, creating a backlog that can increase failure risk and costs over time.

Question 2

Which approach best describes Total Productive Maintenance (TPM)?

Accepted Answer

A program that involves all employees, especially operators, in proactive equipment care to prevent breakdowns

Answer

TPM is a maintenance philosophy that engages all employees—especially machine operators—in proactive equipment care and minor maintenance to prevent failures and maximize productivity.

Question 3

What is the 'P-F interval' in predictive maintenance planning?

Accepted Answer

The time between when a potential failure can first be detected and when functional failure occurs

Answer

The P-F interval is the time between the detection of a potential failure (P point) and the point at which the asset experiences functional failure (F point), defining the window for intervention.

Question 4

Which of the following is a leading indicator of maintenance performance rather than a lagging indicator?

Accepted Answer

Percentage of preventive maintenance tasks completed on schedule

Answer

Planned maintenance compliance (PM tasks completed on schedule) is a leading indicator that predicts future performance, while failure counts and downtime hours are lagging indicators of past performance.

Question 5

In asset maintenance, what are 'critical spares'?

Accepted Answer

Inventory of parts held on hand for assets whose failure would cause major operational impact

Answer

Critical spares are spare parts kept in inventory specifically for assets or components whose failure would cause significant production loss, safety risk, or major service disruption if parts were not immediately available.
