ViSSaAn: Visual Support for Safety Analysis

Yi Yang, Dirk Zeckzer, Peter Liggesmeyer & Hans Hagen
Safety of technical systems are becoming more and more important nowadays. Fault trees and minimal cut sets are usually used to attack the problems of assessing safety-critical systems. A visualization system named ViSSaAn, consisting of a matrix view, is proposed that supports an efficient safety analysis based on the information from these techniques. Interactions such as zooming and grouping are provided to support the task of finding the safety problems from the analysis information. An...
