Safety-critical systems, by definition those systems whose failure can cause catastrophic results for people, the environment, and the economy, are becoming increasingly complex both in their functionality and their interactions with the environment. Unfortunately, safety assessments are still largely done manually, a time-consuming and error-prone process. The growing complexity of these systems requires an increase in the skill and efficacy of safety engineers and encourages the adoption of formal and standardized techniques. An introduction to the area of design and verification of safety-critical systems, Design and Safety Assessment of Critical Systems focuses on safety assessment using formal methods. Beginning with an introduction to the fundamental concepts of safety and reliability, it illustrates the pivotal issues of design, development, and safety assessment of critical systems. The core of the book covers traditional notations, techniques, and procedures, including Fault Tree Analysis, FMECA, HAZOP, and Event Tree Analysis, and explains in detail how formal methods can be used to realize such procedures. It looks at the development process of safety-critical systems, and highlights influential management and organizational aspects. Finally, it describes verification and validation techniques and new trends in formal methods for safety and concludes with some widely adopted standards for the certification of safety-critical systems. Providing an in-depth and hands-on view of the application of formal techniques to advanced and critical safety assessments in a variety of industrial sectors, such as transportation, avionics and aerospace, and nuclear power, Design and Safety Assessment of Critical Systems allows anyone with a basic background in mathematics or computer science to move confidently into this advanced arena of safety assessment.

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.

Dr C P Ellinas Advanced Mechanics & Engineering Ltd Major advances have been achieved in recent years in subsea pipeline design and installation. Inspection, maintenance and repair have also received much attention. The development of marginal fields has brought with it special problems, which have necessitated novel methods and solutions. In the meanwhile interest in the development of deepwater fields continues with the development of new technology. This Conference has placed emphasis in addressing developments in pipeline technology under four main headings: pipeline/seabed interaction; flexible pipelines; pipeline design, fabrication and installation; deepwater applications. Advances in North Sea technology over the last few years have been concerned mostly with marginal fields, small diameter pipelines and new materials, which are well covered in the first three topics. Economic development of marginal fields requires processing of oil and gas to take place not at the wellhead but at existing facilities, usually some distance away. Hydrocarbons are thus often transported at high pressure and temperature in small diameter pipelines, which need to be protected through trenching. However, such operational practice has brought to the fore a problem that in the past was of little concern namely, upheaval buckling.

Whether used for aviation, manufacturing, oil and gas extraction, energy distribution, nuclear or fossil fuel power generation, surveillance or security, all control rooms share two common features. The people operating them are often remote from the processes that they are monitoring and controlling and the operations work 24/7. The twin demands of remote and continuous operation place special considerations on the design of central control rooms. Human Factors in the Design and Evaluation of Central Control Room Operations provides an analysis of Human Factors and Ergonomics in this complex area and the implications for control room staff. This information contained within this book can then be used to design, assessed and evaluate control rooms. Taking an integrated approach to Human Factors and Ergonomics in the control room environment, the book presents fourteen human factors topics: competencies, training, procedures, communications, workload, automation, supervision, shift patterns, control room layout, SCADA interfaces, alarms, control room environment, human error, and safety culture. Although there are many resources available on each of these topics, this book the information together under one cover with a focus on central control room operations. Each chapter is self-contained and can be read in any order, as the information is required.

Safety and Reliability of Industrial Products, Systems and Structures deals with risk assessment, which is a fundamental support for decisions related to the design, construction, operation and maintenance of industrial products, systems and infrastructures. Risks are influenced by design decisions, by the process of construction of systems and infrastructures, and by the way in which they are operated and maintained. The importance of all these aspects vary in the various phases and types of activities, and different methods have been developed to deal with them. Risk analysis, structural reliability and human reliability analysis concentrate on different aspects that complement each other, and in many cases they can be considered separately. As a result of this, and of the different characteristics of the techniques, until today the respective specialists have had little interaction, and not enough efforts have been made to integrate methods. This book, the result of SAFERELNET, a thematic network of 67 organizations from industry, universities and research organizations from 18 countries, is a first attempt to overcome this. Since 2001, SAFERELNET has dealt with providing safe and cost-effective solutions for industrial products, systems, facilities and structures across different industrial sectors. Safety and Reliability of Industrial Products, Systems and Structures covers all aspects of safety issues such as Risk Assessment Methodology; Human and Organisational Factors in Risk Assessments; Integration of Risk and Reliability Formulations; Reliability Based Design; Assessment of Existing Structures and Life Extension; Risk Based Inspection and Maintenance Planning, with a special focus on safety-critical systems in all types of industrial plants, equipment, structural systems, buildings and other civil engineering facilities. The book will be of interest to academia and engineers involved in industrial safety, structural reliability, quantified risk assessment and safety management.

The European Commission emphasizes, in its Fifth Research Framework, the “. . . emerging generic dependability requirements in the information society, stemming both from the ubiquity and volume of embedded and networked systems and services as well as from the global and complex nature of large scale information and communication infrastructures, from citizens, administrations and business in terms of technologies, tools, systems, applications and services". The series of Conference on Computer Safety, Reliability, and Security (Safecomp) contributes to satisfy these requirements by reviewing the state of the art, experiences, and new trends in the relevant scientific and industrial areas. Safecomp is intended to be a platform for technology transfer among academia, industry, and research institutions, providing the opportunity for exchange of ideas, opinions, and visions among experts. This year Safecomp celebrates the 20th anniversary, its first Conference having been organized in Stuttgart by EWICS (European Workshop on Industrial Computer Systems) in 1979, and we hope these Proceedings will contribute to the celebration by supporting Safecomp aims. The Proceedings include the 25 papers that have been presented orally at the Conference and the full version of the 14 papers that have been presented as posters, all of which were selected from 76 submissions. Papers almost uniformly take up Safecomp topics, dealing with the issues of Safety Assessment and Human Factors, Verification and Validation, Design for Safety, Formal Methods, and Security.

"The energy consumption in the world is directly related to the economical growth. The International Energy Agency estimates a doubling increase of electricity demands in the next 25 years (Energy Outlook, 2004). Somehow, this growth must be satisfied without destroying the ecological equilibrium of our planet. For this reason, all sorts of energy resources, which are potential pollutants for the environment are being investigated, and their technologies improved, plus new renewable energies are developed. It is also evident that renewables will take several decades before they are able to substitute the present capacity and even more, to cope with the future energy demands. Nuclear energy is an air pollution free technology with the potential to satisfy the worlds energy demands for many centuries. However, some concerns about the use of nuclear energy have to be further developed in order to recognize nuclear energy as a sustainable option. This book deals with concerns such as the use of nuclear energy for weapons, the risk of accidents with radioactivity release and the waste management."
