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.

Book Synopsis Complex System Reliability by : Albert Myers
Download or read book Complex System Reliability written by Albert Myers and published by Springer Science & Business Media. This book was released on 2010-09-30 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complex System Reliability presents a state-of-the-art treatment of complex multi-channel system reliability assessment and provides the requisite tools, techniques and algorithms required for designing, evaluating and optimizing ultra-reliable redundant systems. Critical topics that make Complex System Reliability a unique and definitive resource include: • redundant system analysis for k-out-of-n systems (including complex systems with embedded k-out-of-n structures) involving both perfect and imperfect fault coverage; • imperfect fault coverage analysis techniques, including algorithms for assessing the reliability of redundant systems in which each element is subject to a given coverage value (element level coverage) or in which the system uses voting to avoid the effects of a failed element (fault level coverage); and • state-of-the-art binary decision diagram analysis techniques, including the latest and most efficient algorithms for the reliability assessment of large, complex redundant systems. This practical presentation includes numerous fully worked examples that provide detailed explanations of both the underlying design principles and the techniques (such as combinatorial, recursive and binary decision diagram algorithms) used to obtain quantitative results. Many of the worked examples are based on the design of modern digital fly-by-wire control system technology. Complex System Reliability provides in-depth coverage of systems subject to either perfect or imperfect fault coverage and also the most recent techniques for correctly assessing the reliability of redundant systems that use mid-value-select voting as their primary means of redundancy management. It is a valuable resource for those involved in the design and reliability assessment of highly reliable systems, particularly in the aerospace and automotive sectors.

Twenty-four scientists have come together to present their views on risks in technological systems. Their scientific disciplines cover not only engineering, economics and medicine, but also history, psychology, literature and philosophy. Taken together these contributions provide a broad, but accurate, interdisciplinary introduction to a field of increasing global interest, as well as rich opportunities to achieve in-depth knowledge of the subject.
Book Synopsis Maintenance for Industrial Systems by : Riccardo Manzini
Download or read book Maintenance for Industrial Systems written by Riccardo Manzini and published by Springer Science & Business Media. This book was released on 2009-11-09 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: New, global and extended markets are forcing companies to process and manage increasingly differentiated products with shorter life cycles, low volumes and reduced customer delivery times. In today’s global marketplace production systems need to be able to deliver products on time, maintain market credibility and introduce new products and services faster than competitors. As a result, a new production paradigm of a production system has been developed and a supporting management decision-making approach simultaneously incorporating design, management, and control of the production system is necessary so that this challenge can be effectively and efficiency met. "Maintenance Engineering and its Applications in Production Systems" meets this need by introducing an original and integrated idea of maintenance: maintenance for productivity. The volume starts with the introduction and discussion of a new conceptual framework based on productivity, quality, and safety supported by maintenance. Subsequent chapters illustrate the most relevant models and methods to plan, organise, implement and control the whole maintenance process (reliability evaluation models and prediction, maintenance strategies and policies, spare parts management, computer maintenance management software – CMMS, and total productive maintenance – TPM, etc.). Several examples of problems supported by solutions, and real applications to help and test the reader’s comprehension are included. "Maintenance Engineering and its Applications in Production Systems" will certainly be valuable to engineering students, doctoral and post-doctoral students and also to maintenance practitioners, as well as managers of industrial and service companies.

Book Synopsis Dependable Computing EDCC-4 by : Fabrizio Grandoni
Download or read book Dependable Computing EDCC-4 written by Fabrizio Grandoni and published by Springer. This book was released on 2003-08-02 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
