Fault tree and gate
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 ...
