This text presents the leading edge in several related fields, specifically object-orientated programming, open distributed systems and formal methods for object-oriented systems. Topics discussed include: object-oriented design and programming; formal specification of distributed systems; open distributed platforms; types, interfaces and behaviour; and formalization of object-oriented methods. This volume comprises the proceedings of the International Workshop on Formal Methods for Open Object-based Distributed Systems (FMOODS '97), sponsored by the International Federation for Information Processing (IFIP) held in Canterbury, United Kingdom, in July 1997.

Originally published in 2002, this book presents techniques in the application of formal methods to object-based distributed systems. A major theme of the book is how to formally handle the requirements arising from OO distributed systems, such as dynamic reconfiguration, encapsulation, subtyping, inheritance, and real-time aspects. These may be supported either by enhancing existing notations, such as UML, LOTOS, SDL and Z, or by defining fresh notations, such as Actors, Pi-calculus and Ambients. The major specification notations and modelling techniques are introduced and compared by leading researchers. The book also includes a description of approaches to the specification of non-functional requirements, and a discussion of security issues. Researchers and practitioners in software design, object-oriented computing, distributed systems, and telecommunications systems will gain an appreciation of the relationships between the major areas of concerns and learn how the use of object-oriented based formal methods provides workable solutions.

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 ZGeneralisations of refinement that change the interface and atomicity of operationsRefinement in Object-ZModelling state and behaviour by combining Object-Z with CSPRefinement in Z and Object-Z: Foundations and Advanced Applications provides an invaluable 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.This second edition is a comprehensive update to the first and includes the following new material:Early chapters have been extended to also include trace refinement, based directly on partial relations rather than through totalisationProvides an updated discussion on divergence, non-atomic refinements and approximate refinementIncludes a discussion of the differing semantics of operations and outputs and how they affect the abstraction of models written using Object-Z and CSPPresents a fuller account of the relationship between relational refinement and various models of refinement in CSPBibliographic notes at the end of each chapter have been extended with the most up to date citations and research

This book covers 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.

It (1) introduces the reader to different ways of looking at refinement, relating refinement to observations(2) shows how these are realised in different semantic models (3) shows how different formal methods use different models of refinement, and (4) how these models of refinement are related.

Refinement is one of the cornerstones of a formal approach to software engineering. Refinement is all about turning an abstract description (of a soft or hardware system) into something closer to implementation. It provides that essential bridge between higher level requirements and an implementation of those requirements. This book provides a comprehensive introduction to refinement for the researcher or graduate student. It introduces refinement in different semantic models, and shows how refinement is defined and used within some of the major formal methods and languages in use today. It (1) introduces the reader to different ways of looking at refinement, relating refinement to observations(2) shows how these are realised in different semantic models (3) shows how different formal methods use different models of refinement, and (4) how these models of refinement are related.

This book constitutes the refereed proceedings of the 4th International Conference on Integrated Formal Methods, IFM 2004, held in Canterbury, UK, in April 2004. The 24 revised full papers presented together with 3 invited papers and one invited tutorial chapter were carefully reviewed and selected from 65 submissions. The papers are devoted to automating program analysis, state/event-based verification, formalizing graphical notions, refinement, object-orientation, hybrid and timed automata, integration frameworks, verifying interactive systems, and testing and assertions.

These proceedings contain papers from the 27th FORTE conference. FORTE (Formal Techniques for Networked and Distributed Systems) is the joint int- national annual conference combining the former PSTV (Protocol Speci?cation Testing and Veri?cation) and former FORTE (Formal Description Techniques for Distributed Systems and Communication Protocols) conferences. The ?rst PSTV conference took place in 1981, and the ?rst FORTE took place in 1988. They were merged into one larger conference in 1996 and have run under the name of FORTE from 2001. The conference is a forum for presentation and d- cussion of the state of the art in theory, application, tools, and industrialization of formal methods. Over the years, FORTE has been held in numerous lo- tions, and this is re?ected by its recent history, with meetings in Pisa (Italy), Cheju Island(Korea),Houston(USA), Berlin(Germany),Madrid(Spain), Paris (France), Taiwan and now Tallinn, Estonia. FORTE was sponsored by Working Group 6.1 of Technical Committee 6 (TC6) of the InternationalFederation for Information Processing (IFIP). Indeed FORTE is one of the ?agship conferences of Working Group 6.1 (Architectures and Protocols for Distributed Systems), and covers many aspects of the main themes of WG6.1, namely, formal description techniques, open distributed s- tems, and quality of service. WG6.1 provided a Best Paper Award as well as funds to help student participation, and we are particularly grateful for this. The 27th FORTE conference was held during June 26–29, 2007, in Tallinn (Estonia), in the historical building of the Brotherhood of the Black Heads.

This book constitutes the refereed proceedings of the 9th International Conference on Integrated Formal Methods, IFM 2012, held Pisa, Italy, in June 2012. The 20 revised full papers presented together with 2 invited papers were carefully reviewed and selected from 59 submissions. The papers cover the spectrum of integrated formal methods, ranging from formal and semiformal notations, semantics, proof frameworks, refinement, verification, timed systems, as well as tools and case studies.
