Full Description
This book presents techniques for the precise description of software or systems using the object-oriented formal specification language, Object-Z. It includes numerous and varied case studies to illustrate the techniques and language of object-oriented formal specification and illustrates the key role of formal specification in formal verification and in implementation. Although primarily intended for safety-critical or complex software development, formal specification also has wide application in hardware or general system description.A practical and rigorous approach to object-oriented formal specification. Introduces Object-Z. Illustrates the key role of formal specification in formal verification by inclusion of example proofs of correctness.
