The use of formal method in the specification of user interfaces has gained an increasing need in software development in the late eighties. Formal specifications are mathematical models representing computer systems. The use of mathematiques in software as hardware system development increases the system's reliability. Testability, ease of maintenance and cost effectiveness…enComputer systemsSystèmes informatiquesLogiciels : FiabilitéFormal methods (Computer science)Méthodes formelles (informatique)Interaction homme-ordinateurComputer programs : Reliability (Engineering)Human-computer interactionThesis
