- CriticalityFailureImportance is also known as failure criticality or criticality importance factor.
- The criticality failure importance for component is the probability that component has caused system failure, when the system has failed at time .
- The criticality failure importance at time for component is given by , where is the Birnbaum importance for component , is the probability that the component has failed, and is the probability that the system has failed.
- The results are returned in the component order given in the distribution list in rdist or fdist.
The result is given in the same order as the distribution list in ReliabilityDistribution:
