Safety is a paradoxical system property. It remains immaterial, intangible and invisible until a failure, an accident or a catastrophy occurs and, too late, reveals its absence. And yet, a system cannot be relied upon unless its safety can be explained, demonstrated and certified. The practical and difficult questions which motivate this study concern the evidence and the arguments needed to justify the safety of a computer based system, or more generally its dependability. Dependability is a broad concept integrating properties such as safety, reliability, availability, maintainability and other related characteristics of the behaviour of a system in operation. How can we give the users the assurance that the system enjoys the required dependability? How should evidence be presented to certification bodies or regulatory authorities? What best practices should be applied? How should we decide whether there is enough evidence to justify the release of the system? To help answer these daunting questions, a method and a framework are proposed for the justification of the dependability of a computer-based system. The approach specifically aims at dealing with the difficulties raised by the validation of software. Hence, it should be of wide applicability despite being mainly based on the experience of assessing Nuclear Power Plant instrumentation and control systems important to safety. To be viable, a method must rest on a sound theoretical background.

Mine Safety combines detailed information on safety in mining with methods and mathematics that can be used to preserve human life. By compiling various recent research results and data into one volume, Mine Safety eliminates the need to consult many diverse sources in order to obtain vital information. Chapters cover a broad range of topics, including: human factors and error in mine safety, mining equipment safety, safety in offshore industry and programmable electronic mining system safety. They are written in such a manner that the reader requires no previous knowledge to understand their contents. Examples and solutions are given at appropriate places, and there are numerous problems to test the reader’s comprehension. Mine Safety will prove useful for many individuals, including engineering and safety professionals working in the mining industry, researchers, instructors, and undergraduate and graduate students in the field of mining engineering.

We think we have scientific knowledge when we know the cause. (Aristotle, Posterior Analytics Book II, Part 11) About 12 years ago, when I was a graduate student, many people were concerned about my Ph. D. topic – investigating the effect of the complexity of procedu- lized tasks on the performance of human operators working in nuclear power plants. Although they agreed with the fact that procedures (especially emergency operating procedures) play a crucial role in securing the safety of nuclear power plants, it was amazing that most of them pointed out a very similar issue: “I cannot understand why operating personnel see any difficulty (or complexity) in condu- ing procedures, because all that they have to do is to follow a simple IF-THEN- ELSE rule as written. ” Actually, this issue is closely related to one of the main questions I was recently asked, such as “Don’t you think your work is too acad- ic to apply to actual procedures?” or “I guess we don’t need to consider the c- plexity of procedures, because we can develop a good procedure using many pr- tical procedure writers’ guidelines. Then what is the real contribution of your work?” I absolutely agree with the latter comment. Yes, we can develop a good pro- dure with the support of many practical and excellent guidelines.

Engineering Decisions for Life Quality: How Safe is Safe Enough? provides a foundation and a theoretical basis for managing risk to an acceptable level under the real-world constraint of limited resources. The focus is not on risks as such, but on what can be done to maximize the positive outcomes of risk in terms of improvements to the quality of life. The principal focus of Engineering Decisions for Life Quality: How Safe is Safe Enough? is on the development of guidance for establishing rational standards of practice. Standards should meet the requirement of utilizing resources to achieve the maximum net overall benefit to society within society’s capacity to commit such resources. The ideas discussed within this book will be of interest to engineers; advanced undergraduate and graduate students; public health officials; and risk specialists.

This Festschrift, dedicated to Cliff Jones, contains papers written by many of his closest collaborators. Cliff has an exceptional international standing for his groundbreaking research and leadership within the practice of formal methods, his career encompasses significant contributions to academia, industry, policy, and service. Cliff is a Fellow of the Royal Academy of Engineering, ACM, BCS, and IET, and in 2015 he was the inaugural Fellow of the Formal Methods Europe association. His career has included industry research in the UK, Austria and Belgium, a PhD at the University of Oxford, and academic and research roles at the University of Cambridge and the University of Manchester, and since 1999 at Newcastle University. Throughout his career, he has championed the essential role of formalism in design processes. His collaboration at IBM in the 1970s led to the creation of the Vienna Development Method (VDM), a seminal contribution that has influenced both practical industry applications and theoretical advancements. Cliff was the founding editor of the ACM journal Formal Aspects of Computing, a founder of the Formal Methods symposium, and he played a pivotal role in the IFIP Working Groups on Programming Methodology and Verified Software. His policy advocacy has been instrumental in fostering public discourse on the reliability of computing systems. The 30 contributions in this volume are a snapshot of the many current scientific developments inspired by or built upon Cliff’s contributions.

It was with great pleasure that, on behalf of the entire organizing committee, I welcomed participants to EDCC-4, the Fourth European Dependable Computing Conference, held for the ?rst time in France. The fourth issue of EDCC carried on the traditions established bythe previous conferences in this series: EDCC-1 was held in Berlin (Germany) in October 1994, EDCC-2 in Taormina (Italy) in October 1996, and EDCC-3 in Prague (Czech Republic) in September 1999. EDCC evolved from a merger of tow other conference series at the moment when the Iron Curtain fell. One of these, known as the ”International Conf- ence on Fault-Tolerant Computing Systems”, was organized during the period 1982–1991, bythe German Technical Interest Group ”Fault-Tolerant Computing Systems”. The other series, known as the ”International Conference on Fault- Tolerant Systems and Diagnostics”, was organized during the period 1975–1990 in the former Czechoslovakia, Poland, Bulgaria, and the former GDR. The c- position of the EDCC steering committee and the organizing committees of the successive issues of the conference have mirrored the East–West uni?cation ch- acter of the conference series. The EDCC conference is becoming a unique meeting point for researchers and practitioners from all over the world in the ?eld of Dependable Systems. It is organized bythe SEE Working Group ”Dependable Computing” in France, the GI/ITG/GMA Technical Committee on Dependabilityand Fault Tolerance in Germany, and the AICA Working Group ”Dependability of Computer Systems” in Italy. Furthermore, committees of several global professional organizations, such as IEEE and IFIP, support the conference.
