M. CARPENTIER Director General DG XIII, Telecommunications, Information Industries and Innovation of the Commission of the European Communities It is with great pleasure that I introduce and recommend this collection of guidelines produced by EWICS TC7. This Technical Committee has consistently attracted technical experts of high quality from all over Europe and the standard of the Committee's work has reflected this. The Committee has been sponsored by the Commission of the European Communities since 1978. During this period, there has been the opportunity to observe the enthusiasm and dedication in the activities of the group, the expertise and effort invested in its work, the discipline in meeting objectives and the quality of the resulting guidelines. It is no surprise that these guidelines have influenced the work of international standardisation bodies. Now the first six of EWICS TCTs guidelines are being made available as a book. I am convinced that all computer system developers who use them will greatly enhance their chances of achieving quality systems. v Acknowledgements In the preparation of this book, the editoLisgrateful to P. Bishop, G. Covington II, C. Goring, and W. Quirk for their help in editing the guidelines. In addition, he would like to thank S. Bologna, W. Ehrenberger, M. Ould, J. Rata, L. Sintonen and J. Zalewski for reviewing the chapters and providing additional material.

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.

This book contains papers on selected aspects of dependability analysis in computer systems and networks, which were chosen for discussion during the 16th DepCoS-RELCOMEX conference held in Wrocław, Poland, from June 28 to July 2, 2021. Their collection will be a valuable source material for scientists, researchers, practitioners and students who are dealing with design, analysis and engineering of computer systems and networks and must ensure their dependable operation. Being probably the most complex technical systems ever engineered by man (and also—the most dynamically evolving ones), organization of contemporary computer systems cannot be interpreted only as structures built on the basis of (unreliable) technical resources. Their evaluation must take into account a specific blend of interacting people (their needs and behaviours), networks (together with mobile properties, cloud organization, Internet of Everything, etc.) and a large number of users dispersed geographically and constantly producing an unconceivable number of applications. Ever-growing number of research methods being continuously developed for dependability analyses apply the newest techniques of artificial and computational intelligence. Selection of papers in these proceedings illustrates diversity of multi-disciplinary topics which are considered in present-day dependability explorations.

This book presents selected papers from the Fifteenth International Conference on Dependability of Computer Systems (DepCoS-RELCOMEX), which illustrate the diversity of theoretical problems in analysis of performability, reliability and security of contemporary computer systems. Covering also methodologies and practical tools involved in this field, it is a valuable reference resource for scientists, researchers, practitioners and students who are dealing with these subjects. Established in 2006, DepCoS-RELCOMEX is an annual conference series organised by Wrocław University of Science and Technology. It focuses on the dependability and performability of contemporary computer systems – topics that can provide solutions to new challenges in evaluation of their reliability and efficiency. Since they are probably the most complex technical systems ever engineered by humans, the organization of modern computer systems cannot be modelled and analysed solely as structures (however complex and distributed) built only on the basis of technical resources. Instead they should be considered as a unique blend of interacting people (their needs and behaviours), networks (together with mobile properties, iCloud organisation, Internet of Everything) and a large number of users dispersed geographically and producing an unimaginable number of applications. This new, interdisciplinary approach is developing a continually increasing range of methods which apply also the latest findings in artificial intelligence (AI) and computational intelligence (CI).

Systems engineers are increasingly having to deal with the problem of how to make the process of designing and constructing dependable computing systems much more predictable and cost-effective. The great challenge about dependability is that it is a systems issue, since virtually all aspects of a computing system, and of the means by which it was specified, designed and constructed, can affect the system's overall dependability. This book explores links, and gaps, between topics that are often investigated separately, but whose interactions can be of considerable relevance to issues of overall system dependability. It contains material on all four of the main topics that are crucial to the successful production of dependable computing systems namely: fault prevention, fault tolerance, fault removal, and fault forecasting. Particular emphasis is placed on the problems of real-time and distributed computing systems. This book provides up to date information about the latest research on these topics from a team made up of many of Europe's leading researchers - it is based on the work of two successive major ESPRIT Basic Research Projects on Predictably Dependable Computing Systems. These projects lasted over six years in total, and each involved approximately forty researchers at any one time. The book contains a carefully edited selection from among the over two hundred published papers produced by the PDCS projects and provides a good general overview of the work of the two projects, as well as coverage of most of the projects' major research achievements.

Increasingly microcomputers are being used in applications where their correct operation is vital to ensure the safety of the public and the environment: from anti-lock braking systems in automobiles, to fly-by-wire aircraft, to shut-down systems at nuclear power plants. It is, therefore, vital that engineers be aware of the safety implications of the systems they develop. This book is an introduction to the field of safety-critical computer systems written for any engineer who uses microcomputers within real-time embedded systems. It assumes no prior knowledge of safety, or of any specific computer hardware or programming language. This text is intended for both engineering and computer science students, and for practising engineers within computer related industries. The approach taken is equally suited to engineers who consider computers from a hardware, software or systems viewpoint.
