Computing systems are of growing importance because of their wide use in many areas including those in safety-critical systems. This book describes the basic models and approaches to the reliability analysis of such systems. An extensive review is provided and models are categorized into different types. Some Markov models are extended to the analysis of some specific computing systems such as combined software and hardware, imperfect debugging processes, failure correlation, multi-state systems, heterogeneous subsystems, etc. One of the aims of the presentation is that based on the sound analysis and simplicity of the approaches, the use of Markov models can be better implemented in the computing system reliability.

A research project to investigate the design and construction of reliable computing systems was initiated by B. Randell at the University of Newcastle upon Tyne in 1972. In over ten years of research on system reliability, a substantial number of papers have been produced by the members of this project. These papers have appeared in a variety of journals and conference proceedings and it is hoped that this book will prove to be a convenient reference volume for research workers active in this important area. In selecting papers published by past and present members of this project, I have used the following criteria: a paper is selected if it is concerned with fault tolerance and is not a review paper and was published before 1983. I have used these criteria (with only one or two exceptions!) in order to present a collection of papers with a common theme and, at the same time, to limit the size of the book to a reasonable length. The papers have been grouped into seven chapters. The first chapter introduces fundamental concepts of fault tolerance and ends with the earliest Newcastle paper on reliability. The project perhaps became well known after the invention of recovery blocks - a simple yet effective means of incorporating fault tolerance in software. The second chapter contains papers on recovery blocks, starting with the paper which first introduced the concept.

As engineering systems become more and more complex, industry has recognized the importance of system and product reliability and places ever increasing emphasis on it during the design phase. Despite its efforts, however, industry continues to lose billions of dollars each year because of unexpected system failures. Therefore, it becomes increasingly important for designers and engineers to have a solid grounding in reliability engineering and keep abreast of new developments and research results.

System reliability, availability and robustness are often not well understood by system architects, engineers and developers. They often don't understand what drives customer's availability expectations, how to frame verifiable availability/robustness requirements, how to manage and budget availability/robustness, how to methodically architect and design systems that meet robustness requirements, and so on. The book takes a very pragmatic approach of framing reliability and robustness as a functional aspect of a system so that architects, designers, developers and testers can address it as a concrete, functional attribute of a system, rather than an abstract, non-functional notion.

"Information security covers the protection of information against unauthorized disclosure, transfer, modification, and destruction, whether accidentally or intentionally. Quality of life in general and of individual citizens, and the effectiveness of the economy critically depends on our ability to build software in a transparent and efficient way. Furthermore, we must be able to enhance the software development process systematically in order to ensure software's safety and security. This, in turn, requires very high software reliability, i.e., an extremely high confidence in the ability of the software to perform flawlessly. Foundations of software technology provide models that enable us to capture application domains and their requirements, but also to understand the structure and working of software systems and software architectures. Based on these foundations tools allow to prove and ensure the correctness of software's functioning. New developments must pay due diligence to the importance of security-related aspects, and align current methods and techniques to information security, integrity, and system reliability. The articles in this book describe the state-of-the-art ideas on how to meet these challenges in software engineering."

Dependability analysis is the recent approach to performance evaluation of contemporary systems which tries to cope with new challenges that are brought with their unprecedented complexity, size and diversity. Especially in case of computer systems and networks such evaluation must be based on multidisciplinary approach to theory, technology, and maintenance of systems which operate in real (and very often unfriendly) environments. As opposed to “classic” reliability which focuses mainly on technical aspects of system functioning, dependability studies investigate the systems as multifaceted and sophisticated amalgamations of technical, information and also human resources. This monograph presents selected new developments in such areas of dependability research as mathematical models, evaluation of software, probabilistic assessment, methodologies, tools, and technologies. Intelligent and soft computing methods help to resolve fundamental problems of dependability analysis which are caused by the fact that in contemporary computer systems it is often difficult to find a relation between system elements and system events (the relation between reasons and results) and it is even more difficult to define strict mathematical models with “analytical” relationships between such phenomena.

Safety of Computer Control Systems is a collection of papers from the Proceedings of the IFAC Workshop, held in Stuttgart, Germany on May 16-18, 1979. This book discusses the inherent problems in the hardware and software application of computerized control to automated systems safeguarding human life, property, and the environment. The papers discuss more specific concerns, such as railway systems, aircraft landing systems, nuclear power stations, chemical reactors, elevators, and cranes. The book also describes the safety and reliability of complex industrial computer systems together with an example showing the application of computers in power plants. One paper presents guidelines in documenting safety related computer systems that will help various parties who are involved in their purchase and operation. Another paper discusses how to detect failures in microcomputer systems such as memory violations and invalid operation code detectors. This book then concludes by discussing the necessity of inspecting process computers used in nuclear power plants, especially when computers are used in reactor protection, control rod, and authentication of log-in systems. This collection can be of interest for students of programming, process-computer analysts, heads of computer technology departments and institutions, and lecturers in industrial computer programming and design.
