Interactive information zoom on Component Fault Trees

Abstract

The visualization approach realized in this work was implemented as extension of the safeTbox modeling tool (safeTbox.iese.fraunhofer.de). It represents a new way in displaying information for component-oriented fault trees (CFTs), in which the goal was to enhance the understandability of hierarchical models while facilitating reviewing purposes. This represents a big advantage for safety analysis, which analyze at system level and which are hindered by the traditional approach of hiding the realization information of components behind the specification views.
