A presentation of real examples of industrial uses for formal
methods such as SCADE, the B-Method, Control Build, Matelo, etc. in
various fields, such as railways, aeronautics, and the automotive
industry, the purpose of this book is to present a summary of
experience on the use of these ‘formal methods’ (such
as proof and model-checking) in industrial examples of complex
systems.
It is based on the experience of people who are currently involved
in the creation and evaluation of safety critical system software.
The involvement of people from within the industry allows us to
avoid the usual problems of confidentiality which could arise and
thus enables us to supply new useful information (photos,
architecture plans, real examples, etc.).
