Prognostics Requirements
A typical prognostics requirement has
four components:
Scope:
a set of failures for which prognosis
is desired
Coverage: the percentage of failures in the
scope that must be prognosed
Horizon:
the time before failure that prognosis
must occur
Accuracy: the desired confidence/correctness
of the prognosis
Prognostics Requirements: Example 1
“Prognostics shall predict at least 70% (with a
95% goal) of the mission critical failures from 480
hours to 96 hours in advance of occurrence with
80% probability.”
Scope:
Mission Critical Failures
Coverage: 70% − 95%
Horizon:
480 + 96 hours
Accuracy:
80%
© 2010 DSI International
Prognostics Requirements: Example 2
“[Prognostics] will accurately predict pending critical
system failures…that might occur in a 72 hour
mission, early enough to allow corrective action
before the unit begins the mission. Prognostics will
provide coverage for 45% SA and 35% EFF at a
90% accuracy (threshold) 70% SA and 65% EFF at
a 99% accuracy rate (objective).”
Scope:
System Aborts
Scope:
Essential Fctn Failures
Coverage: 45% − 70%
Coverage: 35% − 65%
Horizon:
72 hours + CA time
Horizon:
72 hours + CA time
Accuracy:
90% − 99%
Accuracy:
90% − 99%

Prognostics & Diagnostic
Effectiveness
There are two ways in which prognostics
can be considered during diagnostic
analysis:
• Prognosed failures can be included
(analysis reflects the performance of both
prognostics and diagnostics)
• Prognosed failures can be excluded
(analysis reflects the diagnostic performance
for non-prognosed failures only)
