Uncertainty Propagation in Fault-Tree Analysis

  • A. G. Colombo


This paper deals with methods of investigating the propagation of the uncertainty from the lower level (primary event) to the higher level (top) of a complex system, such as a nuclear plant.

A numerical method to determine the probability distribution at each level of the fault-tree is illustrated.
