A collection of papers presented at the PSAM 7 – ESREL ’04 conference in June 2004, reflecting a wide variety of disciplines, such as principles and theory of reliability and risk analysis, systems modelling and simulation, consequence assessment, human and organisational factors, structural reliability methods, software reliability and safety, insights and lessons from risk studies and management/decision making. This volume covers both well-established practices and open issues in these fields, identifying areas where maturity has been reached and those where more development is needed.
These volumes contain the papers presented at the 4th International Conference on Probabilistic Safety Assessment and Management (PSAM 4), held in New York City in September 98. The conference provided a forum for the presentation of innovative methods and applications of risk-based approaches to improve the design and operation of technological systems and processes from the economic and safety points of view. Papers reflect progress made on methods and applications in such areas as modeling and analysis of complex systems, human and organizational performance assessment, software reliability, data collection and analysis, expert judgement modeling and use, identification and assessment of various types of uncertainty, risk-informed regulatory and operational decision making, and public perception of risk. A diverse range of disciplines are represented including aerospace, nuclear, fossil fuels, chemical systems, marine technology, transportation, information technology, medical systems, environment, and defense.
Introduction This book includes terms of reference and offers an augmented volume of relevant work initiated within the comprehensive concept of “Knowledge Management and Risk Governance”. The latter stood for the initial title of an ad-hoc meeting held in Ascona, Switzerland, organized by the Technological Risk Management Unit of the Joint Research Centre of the European Commission (JRC) and the KOVERS Centre of Excellence in Risk and Safety Sciences of the Swiss Federal Institute of Technology, ETH Zurich. Background Risk governance, in addition to the continuous interest of researchers, has recently attracted the attention of policy-makers and the media and the concern of the public. New and emerging risks in various fields and a number of risk-related issues increased the public interest and prompted for a new framework in dealing with risks. The Conference on Science and Governance organized by the European Commission in October 2000 is one of the international forums addressing this issue. Other recent events such as the establishment of the International Risk Governance Council outline the importance of the governance concept in relation to that of risk management (see www.irgc.org). At the same time noticeable progress has been made in Information Technologies and Decision Support, passing from the process of information PREFACE xvi to the process of knowledge. In this context new tools and methods became available, whose application in risk management may be beneficial.

It includes about 570 papers accepted for presentation at the conference. These contributions focus on theories and methods in the area of risk, safety and
Safety Science Research: Evolution, Challenges and New Directions provides a unique perspective into the latest developments of safety science by putting together, for the first time, a new generation of authors with some of the pioneers of the field. Forty years ago, research traditions were developed, including, among others, high-reliability organisations, cognitive system engineering or safety regulations. In a fast-changing world, the new generation introduces, in this book, new disciplinary insights, addresses contemporary empirical issues, develops new concepts and models while remaining critical of safety research practical ambitions. Their ideas are then reflected and discussed by some of the pioneers of safety science. Features Allows the reader to discover how contemporary safety issues are currently framed by a new generation of researchers, brought together for the first time Includes an introduction and guide to the development of safety science over the last four decades Features an extraordinary collection of expert contributors, including pioneers of safety research, reflecting the evolution of the discipline and offering insightful commentary on the current and future state of the field Serves as an invaluable reference and guide for safety professionals and students from any established disciplines such as sociology, engineering, psychology, political science or management as well as dedicated safety programmes Some figures in the eBook are in colour
Petri Nets were defined for the study of discrete events systems and later extended for many purposes including dependability assessment. In our knowledge, no book deals specifically with the use of different type of PN to dependability. We propose in addition to bring a focus on the adequacy of Petri net types to the study of various problems related to dependability such as risk analysis and probabilistic assessment. In the first part, the basic models of PN and some useful extensions are briefly recalled. In the second part, the PN are used as a formal model to describe the evolution process of critical system in the frame of an ontological approach. The third part focuses on the stochastic Petri Nets (SPN) and their use in dependability assessment. Different formal models of SPN are formally presented (semantics, evolution rules…) and their equivalence with the corresponding class of Markov processes to get an analytical assessment of dependability. Simplification methods are proposed in order to reduce the size of analytical model and to make it more calculable. The introduction of some concepts specific to high level PN allows too the consideration of complex systems. Few applications in the field of the instrumentation and control (l&C) systems, safety integrated systems (SIS) emphasize the benefits of SPN for dependability assessment.
Safety is more than the absence of accidents. Safety has the goal of transforming the levels of risk that are inherent in all human activity, while its interdisciplinary nature extends its influence far into most corporate management and government regulatory actions. Yet few engineers have attended a safety course, conference or even a lecture in the area, suggesting that those responsible for the safe construction and operation of complex high-risk socio-technical systems are inadequately prepared. This book is designed to meet the expressed needs of aviation safety management trainees for a practical and concise education supplement to the safety literature. Written in a highly readable and accessible style, its features include: ¢ detailed analysis of the forward-looking System Safety approach, with its focus on accident prevention; ¢ classification of transportation safety literature into distinct schools of thought (Tort Law, Reliability Engineering, System Safety Engineering); ¢ real world, practical, illustrations of the theory; ¢ the history, theory and practice of safety management ; ¢ inter-disciplinary thinking about safety . The flying public is faced with a bewildering array of aviation safety data from a diverse and ever increasing number of sources. This book is an essential guide to the available information, and a major contribution to the international public debate on aviation safety.
The Halden Man-Machine Laboratory (HAMMLAB) has been at the heart of human factors research at the OECD Halden Reactor Project (HRP). The HRP is sponsored by a group of national organizations, representing nuclear power plant regulators, utilities, and research institutions. The HRP is hosted by the Institute for Energy Technology (IFE) in Halden, Norway. HAMMLAB comprises three full-scale nuclear power plant control room research simulators. The simulator studies performed in HAMMLAB have traditionally been experimental in nature. In a simulator it is possible to study events as they unfold in real time, in a highly realistic operational environment under partially controlled conditions. This means that a wide range of human factors issues, which would be impossible or highly impracticable to study in real-life settings, can thus be addressed in HAMMLAB. Simulator-based Human Factors Studies Across 25 Years celebrates the twenty-fifth anniversary of HAMMLAB by reviewing the human factors studies performed in HAMMLAB across this time-span. A range of human factors issues have been addressed, including: • human-system interfaces; • alarm systems; • computerized procedures; • human-automation interaction; • staffing, teamwork and human reliability. The aim of HAMMLAB studies has always been the same: to generate knowledge for solving current and future challenges in nuclear power plant operation to contribute to safety. The outcomes of HAMMLAB studies have been used to support design and assessment of nuclear power plant control rooms.
Current issues and approaches in the reliability and safety analysis of dynamic process systems are the subject of this book. The authors of the chapters are experts from nuclear, chemical, mechanical, aerospace and defense system industries, and from institutions including universities, national laboratories, private consulting companies, and regulatory bodies. Both the conventional approaches and dynamic methodologies which explicitly account for the time element in system evolution in failure modeling are represented. The papers on conventional approaches concentrate on the modeling of dynamic effects and the need for improved methods. The dynamic methodologies covered include the DYLAM methodology, the theory of continuous event trees, several Markov model construction procedures, Monte Carlo simulation, and utilization of logic flowgraphs in conjunction with Petri nets. Special emphasis is placed on human factors such as procedures and training.
