Download or read book Engineering a Safer World written by Nancy G. Leveson and published by MIT Press. This book was released on 2012-01-13 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new approach to safety, based on systems thinking, that is more effective, less costly, and easier to use than current techniques. Engineering has experienced a technological revolution, but the basic engineering techniques applied in safety and reliability engineering, created in a simpler, analog world, have changed very little over the years. In this groundbreaking book, Nancy Leveson proposes a new approach to safety—more suited to today's complex, sociotechnical, software-intensive world—based on modern systems thinking and systems theory. Revisiting and updating ideas pioneered by 1950s aerospace engineers in their System Safety concept, and testing her new model extensively on real-world examples, Leveson has created a new approach to safety that is more effective, less expensive, and easier to use than current techniques. Arguing that traditional models of causality are inadequate, Leveson presents a new, extended model of causation (Systems-Theoretic Accident Model and Processes, or STAMP), then shows how the new model can be used to create techniques for system safety engineering, including accident analysis, hazard analysis, system design, safety in operations, and management of safety-critical systems. She applies the new techniques to real-world events including the friendly-fire loss of a U.S. Blackhawk helicopter in the first Gulf War; the Vioxx recall; the U.S. Navy SUBSAFE program; and the bacterial contamination of a public water supply in a Canadian town. Leveson's approach is relevant even beyond safety engineering, offering techniques for “reengineering” any large sociotechnical system to improve safety and manage risk.
Download or read book Software and System Safety written by Terry L. Hardy and published by AuthorHouse. This book was released on 2012 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: System safety is a widely accepted management and engineering approach to analyze and address risks in complex systems in order to prevent accidents. Because software and computing systems are integral to most systems, software safety has become a critical component of an overall system safety effort. Software and System Safety discusses critical elements of the discipline of system safety and shows how software and computing systems fit in the system safety process. Software-specific aspects of the system safety process are addressed to show concerns common to complex systems. The many accidents and incidents presented in this book illustrate important lessons learned and show how software-related hazards can be misidentified, software risks can be improperly assessed, hazard controls may be misapplied, and software and system testing may not effectively verify that the risk had been reduced. The lessons learned come from a variety of industries and organizations, and include the author’s personal experience. The real-world lessons provided in this book can be used to improve existing software safety and system safety efforts, and can help when planning new system safety programs.

Available in PDF, EPUB and Kindle. Book excerpt: A one-stop reference guide to design for safety principles and applications Design for Safety (DfSa) provides design engineers and engineering managers with a range of tools and techniques for incorporating safety into the design process for complex systems. It explains how to design for maximum safe conditions and minimum risk of accidents. The book covers safety design practices, which will result in improved safety, fewer accidents, and substantial savings in life cycle costs for producers and users. Readers who apply DfSa principles can expect to have a dramatic improvement in the ability to compete in global markets. They will also find a wealth of design practices not covered in typical engineering books—allowing them to think outside the box when developing safety requirements. Design Safety is already a high demand field due to its importance to system design and will be even more vital for engineers in multiple design disciplines as more systems become increasingly complex and liabilities increase. Therefore, risk mitigation methods to design systems with safety features are becoming more important. Designing systems for safety has been a high priority for many safety-critical systems—especially in the aerospace and military industries. However, with the expansion of technological innovations into other market places, industries that had not previously considered safety design requirements are now using the technology in applications. Design for Safety: Covers trending topics and the latest technologies Provides ten paradigms for managing and designing systems for safety and uses them as guiding themes throughout the book Logically defines the parameters and concepts, sets the safety program and requirements, covers basic methodologies, investigates lessons from history, and addresses specialty topics within the topic of Design for Safety (DfSa) Supplements other books in the series on Quality and Reliability Engineering Design for Safety is an ideal book for new and experienced engineers and managers who are involved with design, testing, and maintenance of safety critical applications. It is also helpful for advanced undergraduate and postgraduate students in engineering. Design for Safety is the second in a series of “Design for” books.

Download or read book System Safety written by Felix Redmill and published by Wiley. This book was released on 1999-06-18 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides an indispensable and thorough description of HAZOP (hazard and operability study) - the most powerful technique for the identification and analysis of hazards, a technique which is unknown in many industries and where it is employed, it often does not fulfil its potential because of incorrect use. It describes HAZOP and explains its efficient and effective use. It is a structured text which first teaches HAZOP, step-by-step, and then provides additional information and guidance on particular problems and applications. It therefore provides a course for those who want to learn the technique and a reference source for practitioners. No only have the authors employed, researched and taught the method, but they have also written a standard on its use. They are therefore the ideal advisers, not only for introducing newcomers to HAZOP, but also for guiding practitioners through its more advanced aspects. Key features of this book include: * Detailed discussion and practical examples of the applicatin of HAZOP to software-based systems; * An explanation of the overall context of HAZOP in safety analysis * A method of applying HAZOP to the human components of systems. This will be a crucial teaching and reference text on a safety technique which is used in a wide range of industries, including military, process, rail and other transport, electricity generation, and medical. It explains HAZOP and its application to software-based systems for managers, engineers and safety personnel in all industries.
Download or read book NASA System Safety Handbook written by Homayoon Dezfuli and published by . This book was released on 2012-02-27 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: System safety is the application of engineering and management principles, criteria, and techniques to optimize safety within the constraints of operational effectiveness, time, and cost throughout all phases of the system life cycle. System safety is to safety as systems engineering is to engineering. When performing appropriate analysis, the evaluation is performed holistically by tying into systems engineering practices and ensuring that system safety has an integrated system-level perspective.The NASA System Safety Handbook presents the overall framework for System Safety and provides the general concepts needed to implement the framework. The treatment addresses activities throughout the system life cycle to assure that the system meets safety performance requirements and is as safe as reasonably practicable.This handbook is intended for project management and engineering teams and for those with review and oversight responsibilities. It can be used both in a forward-thinking mode to promote the development of safe systems, and in a retrospective mode to determine whether desired safety objectives have been achieved.The topics covered in this volume include general approaches for formulating a hierarchy of safety objectives, generating a corresponding hierarchical set of safety claims, characterizing the system safety activities needed to provide supporting evidence, and presenting a risk-informed safety case that validates the claims. Volume 2, to be completed in 2012, will provide specific guidance on the conduct of the major system safety activities and the development of the evidence.

Download or read book Safety Analyses of Complex Systems written by Michael Allocco and published by Wiley. This book was released on 2010-04-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Embedded Software Development for Safety Critical Systems written by Chris Hobbs and published by CRC Press. This book was released on 2015-10-06 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Safety-critical devices, whether medical, automotive, or industrial, are increasingly dependent on the correct operation of sophisticated software. Many standards have appeared in the last decade on how such systems should be designed and built. Developers, who previously only had to know how to program devices for their industry, must now understand remarkably esoteric development practices and be prepared to justify their work to external auditors. Embedded Software Development for Safety-Critical Systems discusses the development of safety-critical systems under the following standards: IEC 61508; ISO 26262; EN 50128; and IEC 62304. It details the advantages and disadvantages of many architectural and design practices recommended in the standards, ranging from replication and diversification, through anomaly detection to the so-called "safety bag" systems. Reviewing the use of open-source components in safety-critical systems, this book has evolved from a course text used by QNX Software Systems for a training module on building embedded software for safety-critical devices, including medical devices, railway systems, industrial systems, and driver assistance devices in cars. Although the book describes open-source tools for the most part, it also provides enough information for you to seek out commercial vendors if that’s the route you decide to pursue. All of the techniques described in this book may be further explored through hundreds of learned articles. In order to provide you with a way in, the author supplies references he has found helpful as a working software developer. Most of these references are available to download for free.
Download or read book A System Theoretic Safety Engineering Approach for Software Intensive Systems written by Asim Ali Ahmed Abdulkhaleq and published by Cuvillier Verlag. This book was released on 2017-02-23 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Software safety is a crucial aspect during the development of modern safety-critical systems. However, safety is a system level property, and therefore, must be considered at the system-level to ensure the whole system’s safety. In the software development process, formal verification and functional testing are complementary approaches which are used to verify the functional correctness of software; however, even perfectly reliable software could lead to an accident. The correctness of software cannot ensure the safe operation of safety-critical software systems. Therefore, developing safety-critical software requires a more systematic software and safety engineering process that enables the software and safety engineers to recognize the potential software risks. For this purpose, this dissertation introduces a comprehensive safety engineering approach based on STPA for Software-Intensive Systems, called STPA SwISs, which provides seamless STPA safety analysis and software safety verification activities to allow the software and safety engineers to work together during the software development for safety-critical systems and help them to recognize the associated software risks at the system level.
