Practical Elements of Safety contains the invited papers presented at the Twelfth annual Safety-critical Systems Symposium, held at Birmingham, UK in February 2004. The papers included in this volume focus on the themes of the identification and analysis of risk - using the UK railway as an industry example; safety-integrity levels; industrial use of formal methods; as well as expanding on the development, assessment and changing face of current safety issues. All the papers are linked within the broad context of safety-critical systems actvities and offer a practical perspective. Papers contain industrial experience, as well as academic research, and are presented under the headings of: Mature and Practical Formality, Managing Risk in the Railway Industry, Safety Integrity Levels, the Human Side of Risk, Assessment and the Derivation of Evidence, and Safety Argument and the Law.

Current Issues in Safety-Critical Systems contains the invited papers presented at the eleventh annual Safety-critical Systems Symposium, held in February 2003. All the papers are linked by addressing current issues in safety-critical systems: Dependability Requirements Engineering;

Components of System Safety contains the invited papers presented at the tenth annual Safety-critical Systems Symposium, held in Southampton, February 2002. The papers included in this volume are representative of modern safety thinking, the questions that arise from it, and the investigations that result. They are all aimed at the transfer of technology, experience, and lessons to and within industry, and they offer a broad range of views. Not only do they show what has been done and what could be done, but they also lead the reader to speculate on ways in which safety might be improved.

Aspects of Safety Management contains the invited papers presented at the ninth annual Safety-critical Systems Symposium, held in Bristol, February 2001. For some time, it has been recognised that technical issues are only one side of the safety coin. The other, often dominant feature, is active, informed and committed management. An understanding of risk, emphasis on education and the use of language, attention to learning lessons from both research and other industry sectors, and the development of the appropriate staff competences, are all aspects of safety management. The papers contained within this volume cover a broad range of subjects, but all have the common link of safety management. They present a great deal of industrial experience, as well as some recent academic research.

Lessons in System Safety contains the full set of invited papers presented at the Eighth Annual Safety-critical Systems Symposium, held in Southampton, February 2000. The safety-critical systems domain is rapidly expanding, and its industrial problems are always candidates for academic research. It embraces almost all industry sectors, and lessons learned in one are commonly appropriate to others. The Safety-critical Systems Symposium provides an annual forum for discussing such problems, and the papers in this volume, being from both industrial and academic institutions, all offer lessons in system safety.

This text offers a comprehensive overview of HAZOP (hazard and operability study), a crucial technique for identifying and analyzing hazards. While it remains underutilized in many industries, the authors provide a structured approach to effectively implement HAZOP. The content is designed to teach the technique step-by-step, while also serving as a reference for practitioners facing specific challenges. The authors, experienced in employing, researching, and teaching HAZOP, have even contributed to a standard on its application, making them well-suited to guide both newcomers and seasoned professionals. Key features include a detailed discussion of HAZOP's application to software-based systems, an exploration of its role in safety analysis, and methods for applying HAZOP to the human elements within systems. This resource is essential for managers, engineers, and safety personnel across various sectors, including military, process industries, rail and transport, electricity generation, and healthcare. By explaining HAZOP and its relevance to software systems, this text serves as a vital teaching and reference tool for enhancing safety practices in diverse fields.

Towards System Safety contains the invited papers presented at the seventh annual Safety-critical Systems Symposium, held in Huntingdon, February 1999. The papers bring together practitioners and researchers in a quest to inculate a higher degree of safety engineering into the development and operation of critical software-based systems. In particular, this volume explores recent work and experience which leads us further 'towards system safety'.

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 contributions to this book are the invited papers presented at the fifth annual Safety-critical Systems Symposium. They cover a broad spectrum of issues affecting safety, from a philosophical appraisal to technology transfer, from requirements analysis to assessment, from formal methods to artificial intelligence and psychological aspects. They touch on a number of industry sectors, but are restricted to none, for the essence of the event is the transfer of lessons and technologies between sectors. All address practical issues and of fer useful information and advice. Contributions from industrial authors provide evidence of both safety con sciousness and safety professionalism in industry. Smith's on safety analysis in air traffic control and Rivett's on assessment in the automotive industry are informative on current practice; Frith's thoughtful paper on artificial intelli gence in safety-critical systems reflects an understanding of questions which need to be resolved; Tomlinson's, Alvery's and Canning's papers report on collaborative projects, the first on results which emphasise the importance of human factors in system development, the second on the development and trial of a comprehensive tool set, and the third on experience in achieving tech nology transfer - something which is crucial to increasing safety.

Dependability has always been an vital attribute of operational systems, regardless of whether they are highly-specialised (like electricity generating plants) or more general-purpose (like domestic appliances). This volume provides a highly-readable overview of the topic, concentrating on dependability as a life-cycle management issue rather than as a technical subject. Specifically avoiding technical language and complex mathematics, it is designed to be accessible to readers at all levels. It will be of particular interest to project managers and software engineers in industries where dependability is of particular importance, such as aerospace, process control, and mining. It will also provide useful reading material for students taking courses with modules in dependability. Felix Redmill and Chris Dale have both worked in industry for over 15 years, and now run successful consultancy businesses.
