Описание: An examination of system reliability theory, this title features in-depth discussion of dependability management and reliability centered systems as well as functional safety issues-matters critical to the IEC standards.

Описание: Recent advances in science and technology have made modern computing and engineering systems more powerful and sophisticated than ever. The increasing complexity and scale imply that system reliability problems not only continue to be a challenge but also require more efficient models and solutions. This is the first book systematically covering the state-of-the-art binary decision diagrams and their extended models, which can provide efficient and exact solutions to reliability analysis of large and complex systems. The book provides both basic concepts and detailed algorithms for modelling and evaluating reliability of a wide range of complex systems, such as multi-state systems, phased-mission systems, fault-tolerant systems with imperfect fault coverage, systems with common-cause failures, systems with disjoint failures, and systems with functional dependent failures. These types of systems abound in safety-critical or mission-critical applications such as aerospace, circuits, power systems, medical systems, telecommunication systems, transmission systems, traffic light systems, data storage systems, and etc.

The book provides both small-scale illustrative examples and large-scale benchmark examples to demonstrate broad applications and advantages of different decision diagrams based methods for complex system reliability analysis. Other measures including component importance and failure frequency are also covered. A rich set of references is cited in the book, providing helpful resources for readers to pursue further research and study of the topics. The target audience of the book is reliability and safety engineers or researchers.

The book can serve as a textbook on system reliability analysis. It can also serve as a tutorial and reference book on decision diagrams, multi-state systems, phased-mission systems, and imperfect fault coverage models.

Описание: This practically oriented book presents a comprehensive, up-to-date description of multi-state system (MSS) reliability as a natural extension of classical binary-state reliability. It presents all essential theoretical achievements in the field.

Описание: Recent Advances in System Reliability discusses developments in modern reliability theory such as signatures, multi-state systems and statistical inference. It describes the latest achievements in these fields, and covers the application of these achievements to reliability engineering practice.The chapters cover a wide range of new theoretical subjects and have been written by leading experts in reliability theory and its applications. The topics include: concepts and different definitions of signatures (D-spectra), their properties and applications to reliability of coherent systems and network-type structures; Lz-transform of Markov stochastic process and its application to multi-state system reliability analysis; methods for cost-reliability and cost-availability analysis of multi-state systems; optimal replacement and protection strategy; and statistical inference.Recent Advances in System Reliability presents many examples to illustrate the theoretical results. Real world multi-state systems, such as power generation and transmission, refrigeration, and production systems, are considered in the form of case studies, making the book a useful resource for researchers and postgraduate students.

Описание: Since the introduction of system signatures in Francisco Samaniego`s 1985 paper, the properties of this technical concept have been examined, tested and proven in a wide variety of systems applications.

Описание: A practical guide to facilitate statistically well-founded decisions in the management of assets of an electricity grid Effective and economic electric grid asset management and incident management involve many complex decisions on inspection, maintenance, repair and replacement. This timely reference provides statistically well-founded, tried and tested analysis methodologies for improved decision making and asset management strategy for optimum grid reliability and availability. The techniques described are also sufficiently robust to apply to small data sets enabling asset managers to deal with early failures or testing with limited sample sets. The book describes the background, concepts and statistical techniques to evaluate failure distributions, probabilities, remaining lifetime, similarity and compliancy of observed data with specifications, asymptotic behavior of parameter estimators, effectiveness of network configurations and stocks of spare parts. It also shows how the graphical representation and parameter estimation from analysis of data can be made consistent, as well as explaining modern upcoming methodologies such as the Health Index and Risk Index. Key features: Offers hands-on tools and techniques for data analysis, similarity index, failure forecasting, health and risk indices and the resulting maintenance strategies. End-of-chapter problems and solutions to facilitate self-study via a book companion website. The book is essential reading for advanced undergraduate and graduate students in electrical engineering, quality engineers, utilities and industry strategists, transmission and distribution system planners, asset managers and risk managers.

Описание: Devoted to Multi-State System (MSS) reliability analysis and optimization, this volume provides an historical overview of the field. It presents basic concepts of
MSS, defines MSS reliability measures and systematically describes the tools for MSS reliability assessment and optimization. Basic methods for MSS reliability assessment, such as a
Boolean methods extension, basic random process methods (both Markov and semi-Markov) and universal generating function models, are systematically studied.

A universal
genetic algorithm optimization technique and all details of its application are described. All the methods are illustrated by numerical examples. The book also contains many examples of
application of reliability assessment and optimization methods to real engineering problems.

The aim of this book is to give a comprehensive, up-to-date presentation of MSS
reliability theory based on modern advances in this field and provide a theoretical summary and examples of engineering applications to a variety of technical problems. From this point of
view the book bridges the gap between theoretical advances and practical reliabili
y engineering.

It includes practical examples of the application of these techniques to real life problems.

Описание: As power distribution systems age, the frequency and duration of consumer interruptions will increase significantly. The fundamentals of the design of reliable utility, industrial, and commercial power distribution systems is essential for society because of its complete dependence on a reliable power supply to maintain life activities (e.g., computers, lighting, heating, cooling, etc.). Society must be proactive to minimize the high costs associated with power outages (e.g., $ 10 billion for the last major blackout). It is necessary to consider the cost of power outages when making design decisions for new and existing power distribution systems as well as to have the ability to make quantitative "cost-versus-reliability" trade-off studies. Almost all existing books on reliability do not contain any material on the cost of outages and the methodologies required in trade-off studies required for operation of economical reliable distribution systems. This publication fills the huge void by means of a highly innovative approach applied to practical problems found in the electric distribution industry.

Описание: The book begins with a SCADA/EMS primer aimed at familiarizing the reader with the real-time and study mode data environments in modern control centers. These installations became quite sophisticated and offer superb application integration opportunities that were not available just a few years ago. This background is complemented with a brief review of the stability landscape from the real-time implementation perspective. The subsequent material is clustered along the lines traditionally recognized in the industry from steady-state stability, to transient stability, and to voltage stability. Within these clusters, each chapter describes actual solutions, emphasizes the particular challenges that were faced, shows how the problems were solved, and shades light on the experimental results. The next group of chapters addresses transient stability. Among other things, it describes the implementation of on-line Transient Security Assessment at Southern Company Services by Powertech Labs (Powertech) and provides details about the simulation model, including the dynamic equivalent of the external system, and the complex hardware architecture that supports the computations. Because the book aims primarily at the practical aspects of implementing stability assessment in real-time, the space for theoretical background in each chapter was reduced to the strictest minimum. For the benefit of readers who may not be quite familiar with the underlying theoretical techniques, appendices that describe the key algorithms and discuss some theoretical issues directly related to the subject matter of the book are included at the end.
