Event Trees are one of the most
widely used methods in system risk
analysis. It is an inductive failure
analysis performed to determine the
consequences of single failure for the
overall system risk or reliability.
Event Tree Analysis
uses similar logic and mathematics as
Fault Tree Analysis, but the
approach is different - FTA uses
deductive approach (from system failure
to it's reasons) and ETA uses the
inductive approach (from basic failure
to it's consequences).
An event tree itself is a visual
representation of single failure
sequences, it's influence on other
events and on the whole system.
