This paper presents an automatical fault trees generation method on dynamic systems which has been designed in FIABEX~* [1] (general RAMS Engineering tools). A dynamic system is a system that changes automaticaly its configuration after a failure in order to preserve its mission. This method is based on a systemic functional and dysfunctional modelling of the real system. The aim of this method is to: Generate fault trees using deductive power of reasoning similar to the one used by human intelligence Stop using the classical injection failures method that has reached its limits on complex systems when the order of the studied failure scenario is higher than 2.
