Title:
METHOD AND SYSTEM FOR DETERMINING A FAULT TREE OF A TECHNICAL SYSTEM, COMPUTER PROGRAM PRODUCT AND A COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO2000073903
Kind Code:
A3
Abstract:
According to the invention, faults are written with a fault description which comprises data that has been determined by a failure effect analysis. The fault description is expanded using information concerning the dependence of possible failures and their frequency of occurrence. The fault tree and the frequency of occurrence of the fault event are ascertained for a predetermined fault event from the expanded fault description.
