For efficiency and cost control reasons, system designers' will is to use an integrated set of methods and tools to describe specifications and design, and also to perform dependability analyses. The SAE (Society of Automotive Engineers) AADL (Architecture Analysis and Design Language) has proved to be efficient for architectural modeling. We present a modeling framework allowing the generation of dependability-oriented analytical models from AADL models, to facilitate the evaluation of

The AADL dependability model is transformed into a GSPN (Generalized Stochastic Petri Net) by applying model transformation rules that can be automated. The resulting GSPN can be processed by existing tools. The modeling approach is illustrated on a subsystem of the French Air Traffic Control System.
