Bibliography

Describes fault tree analysis and provides guidance on its application as follows: - definition of basic principles; - describing and explaining the associated mathematical modelling; - explaining the relationships of FTA to other reliability modelling techniques; - description of the steps involved in performing the FTA; - identification of appropriate assumptions, events and failure modes; - identification and description of commonly used symbols.

Describes fault tree analysis and provides guidance on its application to perform an analysis, identifies appropriate assumptions, events and failure modes, and provides identification rules and symbols.
