Definitions
European Project Definitions
CIPRNet project
The CIPRNet project [1] uses the following definition:
Fault trees represent fault sequences of components in which each component is logically decomposed into sub-components (CXX). In a Fault Tree, leaves represent failures of sub-components (fault causes), and the logical.
DIESIS project
The DIESIS project [2] gives the following definition:
Fault trees represent fault sequences of components in which each component is logically decomposed into sub-components (CXX). In a Fault Tree, leaves represent failures of sub-components (fault causes), and the logical nodes are the faults (consequences) of the components.
Other International Definitions
National Definitions
United States
Fault tree is a graphical tool used to illustrate the range, probability, and interaction of causal occurrences that lead to a final outcome. [3]
NIST
Fault tree analysis: A top-down, deductive failure analysis in which an undesired state of a system (top event) is analyzed using Boolean logic to combine a series of lower-level events. An analytical approach whereby an undesired state of a system is specified and the system is then analyzed in the context of its environment of operation to find all realistic ways in which the undesired event (top event) can occur.[4]
Standard Definition
IETF
A branching, hierarchical data structure that is used to represent events and to determine the various combinations of component failures and human acts that could result in a specified undesirable system event. [5]
