Abstract—Formal methods have become more and more widely used in safety-critical software engineering. A system should be specified with a formal model such as automata, Petri nets, and process algebras to be formally verified. We investigated the AADL combined with Object-Z modeling approach for subsequent formal verification work. The advantage of this is that object-oriented ideas can be used for the AADL modeling process. The space-saving effect is achieved by using class inheritance and polymorphism to extract commonalities. In this paper, we present a new formal model with a more powerful ability——OZIA expressed in the language Object-Z. The transformation rules from the AADL-Object-Z model to the OZIA model are defined to support formal verification. Finally, an example illustrates our results with the Aircraft Landing Process case study.
