Error tree is an inductive analytical device in which an event is analyzed using Boolean logic to examine a chronolgical series of subsequent events or consequences.
An Event Tree starts from a specific initiator such as loss of critical supply,[1] or component failure.[2] The event tree develops in time. The event tree models possible further system events including a series of final consequences.
Event tree analysis does not require the premise of a known hazard.[3]
Fault Tree Analysis (FTA) attempts to model and analyze failure processes of engineering and biological systems. FTA is an aspect of reliability engineering.
Some industries use both fault trees and event trees. Software has been created for fault tree analysis and event tree analysis and is licensed for use at almost half of the worlds nuclear power plants for Probabilistic Safety Assessment.
