Description
A package for constructing and calculating fault trees and event trees.
Introduction
ftree provides functions for building tree structures as dataframe objects.
The fault tree incorporates logic nodes (primarily AND and OR) which process input
and may direct output "upwards" through the tree structure. Data is entered through
component entries. Component event entries may be active (failures immediately
revealed) or dormant (failures remain hidden until activation or inspection).
The fault tree may also accept pure probability or pure demand input components.
Event trees are a simpler arrangment of initiating event followed by a series of
mitigating controls. Each mitigating control has a complimentary hazard state
corresponding to failure of the control.
