A practical text suitable for an introductory or advanced course in formal methods, this book presents a mathematical approach to modelling and designing systems using an extension of the B formal method: Event-B. Based on the idea of refinement, the author's systematic approach allows the user to construct models gradually and to facilitate a systematic reasoning method by means of proofs. Readers will learn how to build models of programs and, more generally, discrete systems, but this is all done with practice in mind. The numerous examples provided arise from various sources of computer system developments, including sequential programs, concurrent programs and electronic circuits. The book also contains a large number of exercises and projects ranging in difficulty. Each of the examples included in the book has been proved using the Rodin Platform tool set, which is available free for download at www.event-b.org.

'This present book is the definitive treatment of the new B dialect, written by its creator. Unlike its classical B predecessor which is intended as a reference for the classical B methodology, the present volume is squarely aimed at teaching, though the considerably lighter theory of Event-B permits some of the chapters to act as a reference too.'

'… a rich and accessible book, demonstrating both the strengths and weaknesses of the use of Event-B, and containing varied and valuable case studies as its core. It is written in a pleasant colloquial style, with changes in the vocal tempo and tone leaping off the pages. … should be seriously considered for introductory courses on formal modelling with associated proof.'
