Abstract

This paper introduces a new technique for the verification of both safety and usability requirements for safety-critical interactive systems. This technique uses the model-oriented formal method B and makes use of an hybrid version of the MVC and PAC software architecture models. Our claim is that this technique -that uses proofs obligations- can ensure both usability and safety requirements, from the specification step of the development process, to the implementation. This technique is illustrated by a case study: a simplified user interface for a Full Authority Digital Engine Control (FADEC) of a single turbojet engine aircraft.
