MMC Asset Management & Reliability 2

Question 1

Which reliability metric represents the average time between consecutive failures of a repairable system?

Accepted Answer

MTBF

What does the P-F interval represent on a P-F curve in condition-based maintenance?

Accepted Answer

Time between a detectable potential failure and functional failure

Answer

The P-F interval is the time between when a potential failure (P) becomes detectable and when a functional failure (F) actually occurs.

Question 4

A pump's vibration reading has trended upward over six weeks but remains below the alarm threshold. This is best described as:

Accepted Answer

Incipient failure

Answer

An incipient failure is an early-stage defect that has not yet caused loss of function but is detectable through condition monitoring.

Question 5

Accepted Answer

Operating and maintenance cost

Answer

For most complex industrial assets, operating and maintenance costs over the asset's life significantly exceed initial acquisition costs.
