Formal Techniques for Requirements Analysys for Safety-Critical Systems

Lookup NU author(s): Dr Rogerio De Lemos, Dr Amer Saeed, Emeritus Professor Tom Anderson



Formal support for the different activities performed during requirements analysis demands the utilisation of a set of formal notations and techniques whose features and expressive power match the characteristics of the activities. Selecting an appropriate formal technique for an activity allows emphasis to be placed on pertinent characteristics of the system, enabling the technique to work to its own strengths. In order to facilitate the utilization of different formal techniques, in this paper; we introduce an event/action model (E/A model) as a common foundation for models of system behaviour. To show the flexibility of the E/A model, we incorporate its concepts into two different classes of formalisms.
