A failure-to-restore unavailability model for periodically performed maintenance
Technical Report
·
OSTI ID:5197685
This paper presents a simple mathematical model of the entire restoration/surveillance action that ties together the individual probabilities of errors found in human reliability analyses into an estimate of the unavailability of a component arising from failure to restore after maintenance. This model accounts for failure to restore, surveillance frequency, probability of failing to discover an error during surveillance, and probability of incorrect restoration of the tested component after surveillance.
