Description

ault trees are a popular model in risk analysis: they describe how failures propagate from components to system level: system components are modeled as leaves of the tree, and gates (as AND, OR, priority-AND) in a fault tree model how failures propagate to the top of the tree, which represents that the system has failed.

A wide number of techniques is available to analyse fault trees, both in a qualitative and in a quantitative way: cut sets

Goal of this project is to visualize fault trees: while standard GUIs exist to draw fault trees, and to add the information needed for the analysis, this is not true for the outcomes of the analysis: presention of the results usually done via simple plots.

Hence, we would like to develop more sophisticated and interactive means to visualize a fault tree: various visualization tools and frameworks can be deloyed here --- making fault tree analysis a joy to look at.
