An integrated framework with UML and Object-Z for developing a precise and understandable specification: the light control case study

Presents a framework that integrates a graphical specification technique (UML) with a formal specification technique (Object-Z) to support requirements elicitation and analysis activities. Various UML diagrams are used to specify the system from different concerns during the early requirements elicitation and analysis stage. The information captured in the diagrams is used to develop a complete Object-Z specification. This paper presents a semantic translation from statechart diagrams to Object-Z specifications. Finally, based on information captured in sequence diagrams and use case diagrams, a functional model of the whole system is formally defined. The case study used in this paper is a real-time, interactive and embedded system: a light control system.
