Abstract :
Fault Trees are widely employed in the industrial practice to support safety and reliability analysis. Various works have improved the classic formulation by replacing fixed probabilities of leaf events with Markovian distributions over time. We present operation principles, user interface and implementation architecture of a tool supporting editing and evaluation of Fault Trees where the time of occurrence of leaf events follows a generalized probability density function.
