Event Tree Analysis - ETA
a website created by Relex Software Corporation
This website provides information about event tree analysis (ETA) and how
it relates to reliability and maintainability (RAM) software and analyses.
What is an Event Tree?
An event tree is a visual representation of all the events which can
occur in a system. As the number of events increases, the picture fans out like the
branches of a tree.
Event trees can be used to analyze systems in which all components are continuously
operating, or for systems in which some or all of the components are in standby mode
– those that involve sequential operational logic and switching. The starting point
(referred to as the initiating event) disrupts normal system operation. The event tree
displays the sequences of events involving success and/or failure of the system
components.
In the case of standby systems and in particular, safety and mission-oriented systems,
the event tree is used to identify the various possible outcomes of the system following a
given initiating event which is generally an unsatisfactory operating event or situation.
In the case of continuously operated systems, these events can occur (i.e., components can
fail) in any arbitrary order. In the event tree analysis, the components can be considered
in any order since they do not operate chronologically with respect to each other.
Event Tree Example
A simple example of an event tree is shown below.
This event tree was constructed to analyze the possible outcomes of a system fire. The
system has 2 components designed to handle this event: a sprinkler system and an automated
call to the fire department. If the fire department is not notified, the fire will be
mostly contained by the sprinkler system. If the sprinkler system fails as well, the
system will be destroyed.
The goal of an event tree is to determine the probability of an
event based on the outcomes of each event in the chronological sequence of events leading
up to it. By analyzing all possible outcomes, you can determine the percentage of outcomes
which lead to the desired result.
Using Event Tree with
Reliability Software
Relex Software Corporation produces software
that enables users to easily design event trees and perform ETA quickly and easily. It
allows you to enter the probability or frequency of each separate branch, and calculate
the reliability of all possible outcomes in the event tree.
Relex Software is a leader in R&M (Reliability and Maintainability) software
analysis tools. We specialize in software, training courses, and seminars covering all
aspects of reliability engineering. Our products are used by thousands of engineers
worldwide in a variety of businesses.
