Title:
FAULT TREE ANALYSIS SYSTEM, FAULT TREE ANALYSIS METHOD AND PROGRAMME
Document Type and Number:
WIPO Patent Application WO/2012/115007
Kind Code:
A1
Abstract:
The present invention is a fault tree analysis system which has a k/n gate logical conjunction elimination means for eliminating a logical conjunction that includes a disjointed basic and simple k/n, and eliminating a logical conjunction having a rank which is greater than the maximum rank of the minimal cut-set.
