Our understanding of real-time systems is rapidly approaching a level of maturity which calls for a consolidation of our present knowledge and experience. Particularly effective in influencing our understanding has been the conjoining of universal algebra with the theory and practice of real-time system development. This interplay between algebraic methodology and software technology (AMAST) for real-time systems is the theme for this text.Each chapter, derived from papers presented at the all-invitation 1st AMAST International Workshop on Real-Time Systems (Iowa, 1993), is written by leaders in their field. The chapters form an intriguing mix of modeling, specification, verification, and implementation of “real” real-time systems. They cover untimed and timed systems, sequential, concurrent and embedded real-time processes, integrated models using state machines, temporal logic and algebraic data models, real-time CSP, verification tools, system design using temporal logic, symbolic checking of discrete time models, iterative symbolic approximation in timing verification and verification of audio protocols, timed full LOTOS and timed LOTOS extensions, LOTOS specification of telephone services and flight warning computers, and performance analysis.

This book constitutes the refereed proceedings of the Fourth International AMAST Workshop on Real-Time Systems and Concurrent and Distributed Software, ARTS'97, held in Palma de Mallorca, Spain, in May 1997. The volume presents 24 carefully selected revised full papers. Also included are two historical contributions honoring Ramon Llull, who was born on Mallorca, as well as two invited papers. All current issues in the field of formal methods for real-time systems and distributed and concurrent systems are addressed.

This book collects the research work of leading-edge researchers and practitioners in the areas of analysis, synthesis, design and implementation of real-time systems with applications in various industrial fields. Their works are grouped into six parts, together encompassing twenty chapters. Each part is devoted to a mainstream subject, the chapters therein developing one of the major aspects of real-time system theory, modeling, design, and practical applications. Starting with a general approach in the area of formalization of real-time systems, and setting the foundations for a general systemic theory of those systems, the book covers everything from building modeling frameworks for various types of real-time systems, to verification, and synthesis. Other parts of the book deal with subjects related to tools and applications of these systems. A special part is dedicated to languages used for their modeling and design. The applications presented in the book reveal precious insights into practitioners' secrets.

The first book to provide a comprehensive overview of the subject rather than a collection of papers. The author is a recognized authority in the field as well as an outstanding teacher lauded for his ability to convey these concepts clearly to many different audiences. A handy reference for practitioners in the field.

The CSP approach has been widely used in the specification, analysis and verification of concurrent and real-time systems, and for understanding the particular issues that can arise when concurrency is present. It provides a language which enables specifications and designs to be clearly expressed and understood, together with a supporting theory which allows them to be analyzed and shown to be correct. This book supports advanced level courses on concurrency covering timed and untimed CSP. The first half introduces the language of CSP, the primary semantic models (traces, failures, divergences and infinite traces), and their use in the modelling, analysis and verification of concurrent systems. The second half of the book introduces time into the language, brings in the timed semantic model (timed failures) and finally presents the theory of timewise refinement which links the two halves together.

This volume constitutes the refereed proceedings of the Fourth International Symposium on Formal Techniques in Real-Time and Fault-Tolerant Systems, FTRTFTS '96, held in Uppsala, Sweden, in September 1996. The 22 revised full papers presented were selected from a total of 61 submissions; also included are three invited contributions and five tools demonstrations. The papers are organized in sections on state charts, timed automata, duration calculus, case studies, scheduling, fault tolerance, specification, and verification.

This book constitutes the refereed proceedings of the 6th International Symposium on Formal Techniques in Real-Time and Fault-Tolerant Systems, FTRTFT 2000, held in Pune, India in September 2000. The 21 revised full papers presented together with three invited contributions were carefully reviewed and selected from numerous submissions. The papers are organized in topical sections on model checking, fault tolerance, scheduling, validation, verification, logic and automata.

This book constitutes the refereed proceedings of the 5th International Symposium on Formal Techniques in Real-Time and Fault-Tolerant Systems, FTRTFT'98, held in Lyngby, Denmark, in September 1998. The 22 revised full papers presented were carefully selected and reviewed for inclusion in the book. Also included are four invited contributions and five tool demonstrations. The papers address the current aspects of the hot topic of embedded systems, in particular temporal logic, requirements engineering, analysis techniques, verification, model checking, and applications.

This book constitutes the refereed proceedings of the International Workshop on Hybrid and Real-Time Systems, HART'97, held in Grenoble, France, in March 1997. The volume presents 18 revised full papers and 9 short presentations carefully selected during a highly competitive evaluation process; also included are full versions or abstracts of 7 invited papers or tutorials. Hybrid Systems consist of digital devices interacting with analog environments; thus the emerging area lies at the crossroads of computer science and control theory. This book focusses on mathematically sound methods for the rigorous and systematic design and analysis of hybrid systems and real-time systems.

This book constitutes the refereed proceedings of the Fifth International AMAST Workshop on Formal Methods for Real-Time and Probabilistic Systems, ARTS '99, held in Bamberg, Germany in May 1999. The 17 revised full papers presented together with three invited contributions were carefully reviewed and selected from 33 submissions. The papers are organized in topical sections on verification of probabilistic systems, model checking for probabilistic systems, semantics of probabilistic process calculi, semantics of real-time processes, real-time compilation, stochastic process algebra, and modeling and verification of real-time systems.
