Cause-based decision tree

A set of subtasks are placed in a decision tree or event tree format. The CBDT structure is more like a conventional event tree, expect there are a number of such trees. CBDT formulation is one of a set of HRA methods included within the current EPRI HRA calculator.
CBDT is a development of THERP constructed by Beare and colleagues acting on a suggestion from the operator reliability experiment (ORE) group to develop a decision tree approach to incorporate results from ORE project.
