This book contains the Proceedings of the 6th Safety-critical Systems Sympo sium, the theme of which is Industrial Perspectives. In accordance with the theme, all of the chapters have been contributed by authors having an industrial af filiation. The first two chapters reflect half-day tutorials - Managing a Safety-critical System Development Project and Principles of Safety Management - held on the first day of the event, and the following 15 are contributed by the presenters of papers on the next two days. Following the tutorials, the chapters fa~l into five sub-themes - the session titles at the Symposium. In the first of these, on 'Software Development Tech nology', Trevor Cockram and others report on the industrial application of a requirements traceability model, Paul Bennett on configuration management in safety-critical systems, and Brian Wichmann on Ada. The next 5 chapters are on 'Safety Management'. In the safety domain, the fundamental business of management is increasingly being addressed with respect not merely to getting things done, but also to controlling the processes by which they are done, the risks involved, and the need not only to achieve safety but to demonstrate that it has been achieved. In this context, Gustaf Myhrman reveals recent developments for safer systems in the Swedish De fence, and Shoky Visram reports on the management of safety within a large and complex Air Traffic Control project.

The programme for the Second Safety-critical Systems Symposium was planned to examine the various aspects of technology currently employed in the design of safety-critical systems, as well as to emphasise the importance of safety and risk management in their design and operation. assessment There is an even balance of contributions from academia and industry. Thus, industry is given the opportunity to express its views of the safety-critical domain and at the same time offered a glimpse of the technologies which are currently under development and which, if successful, will be available in the medium-term future. In the field of technology, a subject whose importance is increasingly being recognised is human factors, and there are papers on this from the University of Hertfordshire and Rolls-Royce. Increasingly, PLCs are being employed in safety-critical applications, and this domain is represented by contributions from Nuclear Electric and August Computers. Then there are papers on maintainability, Ada, reverse engineering, social issues, formal methods, and medical systems, all in the context of safety. And, of course, it is not possible to keep the 'new' technologies out of the safety-critical domain: there are papers on neural networks from the University of Exeter and knowledge-based systems from ERA Technology.

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.

Safety-critical systems, in the sense of software-based systems used in safety critical applications, are 'high-tech'. They are products of modern technology. Their effective, efficient and safe functioning depends not only on the devel opment of the right technologies but also on the right use of them. The safety of a system may be compromised not only by faults in the system but also by the use in the first place of an unreliable, unsafe, or unproved technology in its development. The key to the development and use of both technologies and systems is the human being. Until recently, the importance of human involvement, other than at the direct operational level, was hardly admitted. But now the unreliability of humans is recognised, as is the potential for latent faults to be introduced into systems at any point in their life cycles, by all who are in volved with them, including designers and strategic decision makers.
