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 important 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; - a
