To design safety automated systems, the designer must study safety according to various points of view. This paper deals with safety analysis at the stage of control architecture design. The benefits of our work is the taking into account of both software and hardware aspects of the control to analyze the system safety. We illustrate our matter with an example: a cable car system. Several control architectures are considered. Firstly, the reliability of a critical function is analyzed. This analysis will support the choice of an architecture rather than an other one. Secondly, the performances of suggested architectures are evaluated. This evaluation obtained with a Petri nets simulation will allow us to qualify the critical functions.
