XFTA is a Fault Tree assessment engine working on models written at the Open-PSA model exchange format (the reference document is downloadable from the Open-PSA website). XFTA is a fully portable software that runs under Windows and Linux.
XFTA version 1.1 implements an efficient algorithm to compute Minimal Cutsets. This algorithm is original and works for both coherent and non-coherent models. XFTA implements also probabilistic assessments:
Calculation of Safety Integrity Levels requires the calculation of system availability, average availability, system failure intensity, approximation of system reliability, probability of failure on demand, probability of failure per hour…
