This volume contains papers presented at the Third International Conference on Algebraic Methodology and Software Technology (AMAST'93), held at the University of Twente, the Netherlands, 21-25 June 1993. The AMAST conferences aim to promote the use of algebraic methodology as a foundation for software technology, and to examine how universal algebra can provide practical mathematical alternatives to the ad hoc methods commonly used in software development. They are the only conferences to focus specifically on this important area of research. The resulting volume covers a variety of software development issues, and testifies to the versatility of algebraic methods when used as conceptual tools in the software development process. The papers present original research in a range of areas, and include a distinguished collection of invited papers by leading researchers in the field. The volume also includes descriptions of six software systems which have been developed using algebraic methods, techniques and tools.Among the topics covered in this volume are: Algebraic metamathematics; Functional programming; Category theory in software engineering; Modular system design; Real-time system specification; Testing theory and applications; Algebraic semantics of concurrency; Modal logics and reactive systems; Design and refinement principles; Equational and logic programming; Algebraic specification in software engineering.

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 constitutes the refereed proceedings of the 8th International Conference on Algebraic Methodology and Software Technology, AMAST 2000, held in Iowa City, Iowa, USA, in May 2000.The 20 revised full papers presented together with eight invited contributions were carefully reviewed and selected from a total of 53 submissions. Among the topics covered are all current issues in formal methods related to algebraic approaches including abstract data types, abstract state machines, algebraic state machines, algebraic compilers, state charts, process algebras, etc. The algebraic methods are applied to reactive systems, safety-critical systems, concurrency, Java, UML, etc.

SYSTEM SOFTWARE AND SOFTWARE SYSTEMS: Concepts and Methodology is intended to offer a systematic treatment of the theory and practice of designing and implementing system software.The two volumes systematically develop and apply the systems methodology for software development. For that the concept of a system is analysed and various types of systems used in computer science are systematized into a concept of an ad hoc system that is suitable as a mechanism for software development. The kernel of this methodology consists of a systematic approach for ad hoc systems development (specification, implementation, validation). The hardware and the software of a computer system are specified as ad hoc systems. Examples from various architectures, languages, and operating systems are provided as illustrations. Problems and their suggested solutions are provided at the end of each chapter. Further readings and a list of references conclude each chapter.These volumes are self-contained and may be used as textbooks for an introductory course on system software and for a course on operating system. However, a broad spectrum of professionals in computer science will benefit from it.

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.
