While Root Cause Analysis is a set of problem solving methods that is aimed at identifying the root cause of an incident, Fault Tree Analysis is one of the popular techniques that is used in the field of safety engineering to quantitatively determine the probability of a safety hazard. FTA is a deductive, top-down method aimed at analyzing the effects of initiating faults and events on a complex system. There are many software that help you in the Fault Tree Analysis. Some of them are quite expensive but worth every penny.Here in this post we look at some popular Fault Tree Analysis software that are available.

3. ITEM ToolKit
ITEM ToolKit’s Fault Tree Software offers a diverse graphical user interface (GUI) flexible, powerful and easy ways for constructing Fault Trees. The GUI consists of menus, toolbars, and project and system windows. You can simply add different gates and events in the System Window to create a hierarchy of your system, ITEM ToolKit will construct the Fault Tree Diagram for you. You can also build your Fault Tree the traditional way by adding gates and events in the Diagram Window.

4. FaultTree+
FaultTree+ is the world’s most popular fault tree software package incorporating fault tree analysis, event tree analysis and Markov analysis. FaultTree+ has three different modules. The Fault Tree Analysis module allows you to construct and analyze fault tree diagrams. The Event Tree Analysis allow you to analyze the possible outcomes of an event occurring. And the Markov Analysis enables the construction of Markov models for components with large interdependencies.
