Specifying Modal Systems using Event-B

This is the latest version of this item.



Several safety-critical systems, such as avionic, transportation and space systems, use the notion of operation modes. Operation modes are useful structuring units that facilitate design, specially if used with state-based formal methods. However, modelling abstractions to support the specification, analysis and correct construction of modal systems are still lacking. The contribution of this paper is twofold: (i) modal systems and modal systems refinement are discussed and formalized; (ii) the relation of a modal system specification with an Event-B model is discussed, showing how to demonstrate that the behaviour of an Event-B model can satisfy a modal system.
