Fault trees, event trees and success trees

1993
Fault-tree analysis was developed by H.A. Watson of the Bell Telephone Laboratories in 1961–2 as part of a US Air Force study contract for the Minuteman missile launch control system. Through the years it has proved to be a very valuable tool for the reliability evaluation of complex systems, such as nuclear power stations, chemical plants, wide-body ...
