Accepted Answer

Causes and barriers preventing the top event

Answer

The left side of a bow-tie diagram shows threat pathways and preventive barriers that stop the top event from occurring.

Question 2

Which failure distribution is most commonly used in RAM analysis to model the useful-life period of a component?

Accepted Answer

Exponential distribution

Answer

The exponential distribution is used for the useful-life (constant hazard rate) phase where failures occur randomly and independently.

Question 3

A system's inherent availability differs from operational availability primarily because:

Accepted Answer

Operational availability includes all scheduled and logistic delays

Answer

Operational availability accounts for all downtime including logistics and administrative delays, while inherent availability only considers active repair time.

Question 4

What is the primary risk mitigation benefit of Prognostics and Health Management (PHM) systems?

Accepted Answer

Predicting failures before they occur to enable proactive maintenance

Answer

PHM monitors system health indicators to predict failures in advance, converting unplanned failures into planned maintenance.

Question 5
