Formal methods of software development rely on the validation of the specification of the software. Such specification is normally expressed in a formal language such as Z. However, in order to be validated the Z specification must be tested, and to achieve this it has to be transformed into a form that can be executed or animated. Prolog was one of the languages used for animation of Z specifi...

This paper presents the formal aspects of testing criteria for Safety Critical Systems. A brief review of testing strategies i.e. white box and black box is given along with their various criteria’s. Z Notation; a formal specification language is used to sever the purpose of formalization. Initially, the schemas are formed for Statement Coverage (SC), Decision coverage (DC), Path Coverage (PC),...

1 Introduction This annotated Z bibliography contains a selected list of some pertinent publications for Z users. Most of those included are readily available, either as books or in journals. A few unpublished items have been included, where they are particularly relevant and can be obtained reasonably easily. Some references are accompanied by an annotation. This may include a contents list (o...

Many practitioners agree on the key role of object associations during the requirements specification and analysis phases of application development, since they contribute to the definition of the semantics of applications. However, the literature shows that there are multiple semantics for associations, and confusion about how they should be represented. As a matter of fact, various interpreta...

It is not surprising that students are unconvinced about the benefits of formal methods if we do not show them how these methods can be integrated with other activities in the software lifecycle. In this paper, we describe an approach to integrating formal specification with more traditional verification and validation techniques in a course that teaches formal specification and specification-b...

The combination of the two well known formal specification techniques CSP [Hoa78] for specification of behavioural aspects of systems and Object-Z (OZ) for specification of data aspects of systems into the specification language CSP-OZ [Fis97] has already been subject of intense research. An important challenge is their inherent complexity which quickly goes beyond the scope of current analysis...

Design and specification is a serious issue in software engineering because of the semantics involved in transforming the real world problems to computer software systems. Unified Modeling Language (UML) has been accepted as a de facto standard for design and specification of object oriented systems. Unfortunately, UML structures lack defining semantics of a system. Formal methods are proved po...

Over the past years, a number of increasingly expressive languages for modelling constraint and optimisation problems have evolved. In developing a strategy to ease the complexity of building models for constraint and optimisation problems, we have asked ourselves whether, for modelling purposes, it is really necessary to introduce more new languages and notations. We have analyzed several emer...
