Refinement in Z and Object-Z

Refinement is one of the cornerstones of the formal approach to software engineering, and its use in various domains has led to research on new applications and generalisation. This book brings together this research in one volume, with the addition of examples drawn from different application areas. It covers four main themes: - data refinement and its application to Z - generalisations of refinement that change the interface and atomicity of operations - refinement in Object-Z - and modelling state and behaviour by combining Object-Z with CSP. Refinement in Z and Object-Z: Foundations and Advanced Applications provides an overview of recent research for academic and industrial researchers, lecturers teaching formal specification and development, industrial practitioners using formal methods in their work, and postgraduate and advanced undergraduate students.
