WebRelationship Between Fault Trees and Event Trees –As discussed in Module E, event trees consist of a series of nodes. Each node represents the success or failure of a particular system, component, or operation. –For complex systems, fault tree models are used to model system failure and estimate the system's probability of failure. WebSAPHIRE has been designed to handle large fault trees, where a tree may have up to 64,000 basic events and gates. To handle the fault trees, two mechanisms for developing and modifying the fault tree are available – a graphical editor and a hierarchical logic editor.
