Development and Application of Risk-Analysis Techniques and Associated Data Bases. Final Report, 1 September 1981-15 May 1983.

摘要

This final report concludes the project dealing with risk analysis techniques and related data bases. The bulk of the reporting on the project was contained in the Technical Report of December, 1983, but this report contains a more-extensive description of the use of the FRANTIC II computer program. The FRANTIC (Formal Reliability Analysis including Normal Testing, Inspection, and Checking Program) is a FORTRAN Computer Code which computes the average and time-dependent unavailability of any general system model such as a fault tree or event tree, incorporating in detail the effects of different periodic testing schemes. The program can be used to assess the effects on system unavailability of test downtimes, repair times, test efficiency, test bypass capabilities, test-caused failures, and different test staggerings. In addition to periodically tested components, non-repairable and monitored components can be modeled as can human error and common causes of failures. The FRANTIC-II Code incorporates the use of the Weibull distribution, which has a time-dependent failure rate. (ERA citation 08:034956)
