Supervision and Safety of Complex Systems


Book Description

This book presents results of projects carried out by both scientific and industry researchers into the techniques to help in maintenance, control, supervision and security of systems, taking into account the technical environmental and human factors. This work is supported by the Scientific Group GIS 3SGS. It is a collaborative work from 13 partners (academic and industrial) who have come together to deal with security problems. The problems and techniques discussed mainly focus on stochastic and dynamic modeling, maintenance, forecasting, diagnosis, reliability, performance, organizational, human and environmental factors, uncertainty and experience feedback.




Safety Analyses of Complex Systems


Book Description

There is a need for more inclusive holistic approaches to identify and analyze safety-related system risks. Systems are becoming increasingly more complex, diverse, and vastly distributed. Conventional approaches of conducting hazard analyses and risk assessment do have limitations. This book addresses some of these limitations and a number of inclusive approaches are discussed, which can be applied against the limitations. The book emphasizes scenario-driven hazard analysis as a means to conduct more holistic analysis. It discusses safety analyses of large complex systems; which are comprised of software, firmware, hardware, the human and the environment. “System thinking” in problem solving is emphasized throughout the book. The book is comprised of three parts. The first part Risk identification covers topics including understanding risk, evaluating safety, and scenario-driven hazard analysis. The second part Risk elimination and control addresses eliminating risk and provides hazard control methods, techniques, and applications. Finally managing safety-related risks covers key concepts and observations associated with a safety management and other topics including making safety-related decisions. At the end of each chapter there are “Questions and Topics for Further Discussion”, which enables the book to be used for graduate and undergraduate education, and specialized courses or instructional development.







Complex Systems


Book Description

This book gives a wide-ranging description of the many facets of complex dynamic networks and systems within an infrastructure provided by integrated control and supervision: envisioning, design, experimental exploration, and implementation. The theoretical contributions and the case studies presented can reach control goals beyond those of stabilization and output regulation or even of adaptive control. Reporting on work of the Control of Complex Systems (COSY) research program, Complex Systems follows from and expands upon an earlier collection: Control of Complex Systems by introducing novel theoretical techniques for hard-to-control networks and systems. The major common feature of all the superficially diverse contributions encompassed by this book is that of spotting and exploiting possible areas of mutual reinforcement between control, computing and communications. These help readers to achieve not only robust stable plant system operation but also properties such as collective adaptivity, integrity and survivability at the same time retaining desired performance quality. Applications in the individual chapters are drawn from: • the general implementation of model-based diagnosis and systems engineering in medical technology, in communication, and in power and airport networks; • the creation of biologically inspired control brains and safety-critical human–machine systems, • process-industrial uses; • biped robots; • large space structures and unmanned aerial vehicles; and • precision servomechanisms and other advanced technologies. Complex Systems provides researchers from engineering, applied mathematics and computer science backgrounds with innovative theoretical and practical insights into the state-of-the-art of complex networks and systems research. It employs physical implementations and extensive computer simulations. Graduate students specializing in complex-systems research will also learn much from this collection./pp










Fault Detection, Supervision, and Safety for Technical Proceses


Book Description

Paperback. Fault detection, supervision and safety are an essential part of modern control engineering. In this publication, over two hundred experts from various fields and application areas present their latest results on reliability, availability and safety of technical processes, covering both theoretical and practical problems. Applications in all phases are covered, from design, start-up, operation, maintenance through to repair. Relevant methods and tools for monitoring, diagnosis and detection are discussed as well as the increasingly important topics of failure data collection and analysis, human factors and man-machine interfaces. This volume lays strong emphasis on applications and aims to promote further research and industrial co-operation.

Learning and Relearning Equipment Complexity


Book Description

With industrial systems becoming ever more mechanized and reliant on advanced technology, the complexity of equipment, especially in risky industries, is increasing on a daily basis. A thorough understanding of operations and providing safety for these complex systems has become a firm requirement for many. This book offers the knowledge required by safety professionals to provide and maintain the safety of engineering complex systems. Through a scientific and engineering approach to designing, implementing, operating, and maintaining complex systems, Learning and Relearning Equipment Complexity: Achieving Safety in Engineering Complex Systems details the need for more engineering and scientific knowledge to understand and maintain their safety. It gives clear explanations of reasons for a system’s complexity, based on control systems and non-linear dynamics. In addition, the book addresses the necessary changes in the approach and the procedures for the safety assessment of engineering complex systems. The reader will develop a thorough understanding of what complex systems are, why they are complex, and how they are utilized. This book will appeal to any safety professional tasked with complex systems. This extends to professionals in risky industries such as aviation, nuclear power, chemicals, railway and transport, and pharmaceuticals.




Data-Centric Safety


Book Description

Data-Centric Safety presents core concepts and principles of system safety management, and then guides the reader through the application of these techniques and measures to Data-Centric Systems (DCS). The authors have compiled their decades of experience in industry and academia to provide guidance on the management of safety risk. Data Safety has become increasingly important as many solutions depend on data for their correct and safe operation and assurance. The book’s content covers the definition and use of data. It recognises that data is frequently used as the basis of operational decisions and that DCS are often used to reduce user oversight. This data is often invisible, hidden. DCS analysis is based on a Data Safety Model (DSM). The DSM provides the basis for a toolkit leading to improvement recommendations. It also discusses operation and oversight of DCS and the organisations that use them. The content covers incident management, providing an outline for incident response. Incident investigation is explored to address evidence collection and management.Current standards do not adequately address how to manage data (and the errors it may contain) and this leads to incidents, possibly loss of life. The DSM toolset is based on Interface Agreements to create soft boundaries to help engineers facilitate proportionate analysis, rationalisation and management of data safety. Data-Centric Safety is ideal for engineers who are working in the field of data safety management. This book will help developers and safety engineers to: Determine what data can be used in safety systems, and what it can be used for Verify that the data being used is appropriate and has the right characteristics, illustrated through a set of application areas Engineer their systems to ensure they are robust to data errors and failures
