Fault Tree Analysis (FTA) - What Is It, Examples, Steps, Diagram

WebFault tree diagrams represent the logical relationship between sub-system and component failures and how they combine to cause system failures. The TOP event of a fault tree represents a system event of interest and is connected by logical gates to component failures known as basic events. After creating the diagram, failure and repair data is ... WebFault trees can become quite large and complex, containing many gates and events. In these cases, for ease of analysis, it might be helpful to break the single fault tree up into smaller fault trees that are all linked together. Additionally, you might want to repeat the same logic in two different places.
