A first attempt to combine SysML requirements diagrams and B
Résumé
This article describes a work-in-progress in the framework of a research project aiming at combining requirements engineering methods with formal methods. The main idea is to extend the SysML language with concepts of existing requirements engineering methods. In this article we present extensions to SysML with concepts from the goal model of the KAOS method and we give rules to derive a formal B specification from this goal model. The approach is then illustrated on a case study.
