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

ABSTRACT: This paper addresses two issues: how formal object modeling techniques facilitate the XML application development and how XML technology helps formal/graphical software design process. In particular, the paper presents a XML/XSL approach to the development of a web environment for Z family languages (Z/Object-Z/TCOZ). The projection techniques and tools from object-oriented Z (in XML) to UML (in XMI) are developed using XSL Transformations (XSLT). Furthermore, object-oriented Z is used to specify and design the essential functionalities of the web environment and the projection tools to UML. In a sense, the paper also demonstrates a formal object approach to modeling XML applications.Annals of Software Engineering 01/2002; 13:329-356.

ABSTRACT: This paper presents the XML/XSL approach to the developmentofaweb environment for the formal specification language Object-Z. The projection techniques and tools from Object-Z (in XML) to UML (in XMI) are developed using XSL Transformations (XSLT). Furthermore, Object-Z (itself) is used to specify and design the essential functionalities of the web environment and the projection tools to UML. In a sense, the paper also demonstrates a formal approach to modeling web applications. Keywords Object-Z, XML/XSL/XMI, UML 1.04/2001;
Conference Paper: Formalization of UML use case diagram-a Z notation based approach[Show abstract] [Hide abstract]
ABSTRACT: A Unified Modeling Language (UML) use case diagram is a visual tool that provides a way for developers to come to a common understanding with system's end users and domain experts. The behavior of a use case can be specified by describing a flow of events in text for an outsider to understand it easily. The flow of events of a use case is specified in an informal structured text. Therefore, it is not possible to automate the verification of tracking requirements captured in a use case diagram in the design phase. On the other hand, Z is a formal language, which is non-executable, but, a strongly typed specification language. We here propose a structured-expandable format of a use case, which is expressed in Z notation and then represented visually using an Entity-Relationship diagram. Implementation of our approach would bridge the gap between a formal language, which is mathematical and difficult to understand and UML use case diagram that is visual, easy to comprehend and that is used widely to capture requirements. Development of a tool based on this approach will produce a visual representation of a formalized UML use case diagram, from which automated traceability and verification of the design phase can be achieved.Computing & Informatics, 2006.
