Book Description
This is the digital version of the printed book (Copyright © 1987). Here is a casebook, a practical reference, and an indispensable guide for creating a systematic, formal methodology for large, real-time, software-based systems. The book introduces the widely implemented Hatley/Pirbhai methods, a major extension of the DeMarco analysis method describing how external events control the system's operating behavior. The techniques are used in major avionics and electronics companies worldwide, and are automated by most major CASE tools, including TurboCASE/Sys by StructSoft, Inc. Large software-based systems, especially those for real-time applications, require multi-mode operation, direct interaction with a rapidly changing physical environment, and fast response times. In the past, the development of such systems was prone to massive cost and schedule overruns, and to inadequate performance and reliability. Strategies for Real-Time System Specification addresses these problems by integrating a finite-state machine structure into classical analysis methods. The book contains nearly 200 diagrams, many of which illustrate the requirements specification of a flight management system for a major avionics developer.

Book Description
This is the digital version of the printed book (Copyright © 2000). Derek Hatley and Imtiaz Pirbhai—authors of Strategies for Real-Time System Specification—join with influential consultant Peter Hruschka to present a much anticipated update to their widely implemented Hatley/Pirbhai methods. Process for System Architecture and Requirements Engineering introduces a new approach that is particularly useful for multidisciplinary system development: It applies equally well to all technologies and thereby provides a common language for developers in widely differing disciplines. The Hatley-Pirbhai-Hruschka approach (H/H/P) has another important feature: the coexistence of the requirements and architecture methods and of the corresponding models they produce. These two models are kept separate, but the approach fully records their ongoing and changing interrelationships. This feature is missing from virtually all other system and software development methods and from CASE tools that only automate the requirements model. System managers, system architects, system engineers, and managers and engineers in all of the diverse engineering technologies will benefit from this comprehensive, pragmatic text. In addition to its models of requirements and architecture and of the development process itself, the book uses in-depth case studies of a hospital monitoring system and of a multidisciplinary groundwater analysis system to illustrate the principles. Compatibility Between the H/H/P Methods and the UML: The Hatley/Pirbhai architecture and requirements methods—described in Strategies for Real-Time System Specification—have been widely used for almost two decades in system and software development. Now known as the Hatley/Hruschka/Pirbhai (H/H/P) methods, they have always been compatible with object-oriented software techniques, such as the UML, by defining architectural elements as classes, objects, messages, inheritance relationships, and so on. In Process for System Architecture and Requirements Engineering, that compatibility is made more specific through the addition of message diagrams, inheritance diagrams, and new notations that go with them. In addition, state charts, while never excluded, are now specifically included as a representation of sequential machines. These additions make definition of the system/software boundary even more straightforward, while retaining the clear separation of requirements and design at the system levels that is a hallmark of the H/H/P methods—not shared by most OO techniques. Once the transition to software is made, the developer is free to continue using the H/H/P methods, or to use the UML or any other software-specific technique.

Book Description
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 practitionersOCO secrets."

Book Description
WHAT IS THIS BOOKABOUT7 In recent times real-time computer systems have become increasingly complex and sophisticated. It has now become apparent that, to implement such schemes effectively, professional, rigorous software methods must be used. This includes analysis, design and implementation. Unfortunately few textbooks cover this area well. Frequently they are hardware oriented with limited coverage of software, or software texts which ignore the issues of real-time systems. This book aims to fill that gap by describing the total software design and is given development process for real-time systems. Further, special emphasis of microprocessor-based real-time embedded systems. to the needs WHAT ARE REAL-TIME COMPUTER SYSTEMS? Real-time systems are those which must produce correct responses within a definite time limit. Should computer responses exceed these time bounds then performance degradation and/or malfunction results. WHAT ARE REAL-TIME EMBEDDED COMPUTER SYSTEMS? Here the computer is merely one functional element within a real-time system; it is not a computing machine in its own right. WHO SHOULD READ THIS BOOK? Those involved, or who intend to get involved, in the design of software for real-time systems. It is written with both software and hardware engineers in mind, being suitable for students and professional engineers.

Book Description
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.
