Coud reliability engineering is a leading issue of cloud services. Cloud service providers guarantee computation, storage and applications through service-level agreements (SLAs) for promised levels of performance and uptime. Cloud Reliability Engineering: Technologies and Tools presents case studies examining cloud services, their challenges, and the reliability mechanisms used by cloud service providers. These case studies provide readers with techniques to harness cloud reliability and availability requirements in their own endeavors. Both conceptual and applied, the book explains reliability theory and the best practices used by cloud service companies to provide high availability. It also examines load balancing, and cloud security. Written by researchers and practitioners, the book's chapters are a comprehensive study of cloud reliability and availability issues and solutions. Various reliability class distributions and their effects on cloud reliability are discussed. An important aspect of reliability block diagrams is used to categorize poor reliability of cloud infrastructures, where enhancement can be made to lower the failure rate of the system. This technique can be used in design and functional stages to determine poor reliability of a system and provide target improvements. Load balancing for reliability is examined as a migrating process or performed by using virtual machines. The approach employed to identify the lightly loaded destination node to which the processes/virtual machines migrate can be optimized by employing a genetic algorithm. To analyze security risk and reliability, a novel technique for minimizing the number of keys and the security system is presented. The book also provides an overview of testing methods for the cloud, and a case study discusses testing reliability, installability, and security. A comprehensive volume, Cloud Reliability Engineering: Technologies and Tools combines research, theory, and best practices used to engineer reliable cloud availability and performance.

Next Generation HALT and HASS presents a major paradigm shift from reliability prediction-based methods to discovery of electronic systems reliability risks. This is achieved by integrating highly accelerated life test (HALT) and highly accelerated stress screen (HASS) into a physics-of-failure-based robust product and process development methodology. The new methodologies challenge misleading and sometimes costly mis-application of probabilistic failure prediction methods (FPM) and provide a new deterministic map for reliability development. The authors clearly explain the new approach with a logical progression of problem statement and solutions. The book helps engineers employ HALT and HASS by illustrating why the misleading assumptions used for FPM are invalid. Next, the application of HALT and HASS empirical discovery methods to quickly find unreliable elements in electronics systems gives readers practical insight to the techniques. The physics of HALT and HASS methodologies are highlighted, illustrating how they uncover and isolate software failures due to hardware-software interactions in digital systems. The use of empirical operational stress limits for the development of future tools and reliability discriminators is described. Key features: * Provides a clear basis for moving from statistical reliability prediction models to practical methods of insuring and improving reliability. * Challenges existing failure prediction methodologies by highlighting their limitations using real field data. * Explains a practical approach to why and how HALT and HASS are applied to electronics and electromechanical systems. * Presents opportunities to develop reliability test discriminators for prognostics using empirical stress limits. * Guides engineers and managers on the benefits of the deterministic and more efficient methods of HALT and HASS. * Integrates the empirical limit discovery methods of HALT and HASS into a physics of failure based robust product and process development process.

As such, studies of reliability properties of consecutive k-out-of-n structures have attracted significant attention from both theoretical and practical approaches. In the modern era of technology, the redundancies are employed in the various industrial systems to prevent them from failure/sudden failure or to recover from failures. This book is meant to provide knowledge and help engineers and academicians in understanding reliability engineering by using k-out-of-n structures. The material is also targeted at postgraduate or senior undergraduate students pursuing reliability engineering.

This book provides a comprehensive overview of recent advances in the analysis and design of health management systems for cooperating unmanned aerial vehicles. Such systems rely upon monitoring and fault adaptation schemes. Motivation for their study comes from the fact that, despite the use of fault-tolerant control software and hardware embedded onboard air vehicles, overall fleet performance may still be degraded after the occurrence of anomalous events such as systems faults and failures. Cooperative health management (CHM) systems seek to provide adaptation to the presence of faults by capitalizing on the availability of interconnected computing, sensing and actuation resources.

This monograph complements the proposed CHM concepts by means of case studies and application examples. It presents fundamental principles and results encompassing optimization, systems theory, information theory, dynamics, modeling and simulation. Written by pioneers in cooperative control, health management and fault-tolerant control for unmanned systems, this book is a unique source of information for designers, researchers and practitioners interested in the field.

Estimating Device Reliability: Assessment of Credibility is concerned with the plausibility of reliability estimates obtained from statistical models. Statistical predictions are necessary because technology is always pushing into unexplored areas faster than devices can be made long-lived by design. Flawed reliability methodologies can produce disastrous results, an outstanding example of which is the catastrophic failure of the manned space shuttle CHALLENGER in January 1986. This issue is not whether, but which, statistical models should be used. The issue is not making reliability estimates, but is instead their credibility. The credibility questions explored in the context of practical applications include: What does the confidence level associated with the use of statistical model mean? Is the numerical result associated with a high confidence level beyond dispute? When is it appropriate to use the exponential (constant hazard rate) model? Does this model always provide the most conservative reliability estimate? Are the results of traditional random' failure hazard rate calculations tenable? Are there persuasive alternatives? What model should be used to describe the useful life of a device when wearout is absent? When Weibull and lognormal failure plots containing a large number of failure times appear similar, how should the correct wearout model be selected? Is it important to distinguish between a conservative upper bound on a probability of failure and a realistic estimate of the same probability? Estimating Device Reliability: Assessment of Credibility is for those who are obliged to make reliability calculations with a paucity of somewhat corrupt data, by using inexactmodels, and by making physical assumptions which are impractical to verify. Illustrative examples deal with a variety of electronic devices, ICs and lasers.

Today, engineering systems are an important element of the world economy and each year billions of dollars are spent to develop, manufacture, operate, and maintain various types of engineering systems around the globe. Many of these systems are highly sophisticated and contain millions of parts. For example, a Boeing jumbo 747 is made up of approximately 4.5 million parts including fasteners. Needless to say, reliability, safety, and maintenance of systems such as this have become more important than ever before. Global competition and other factors are forcing manufacturers to produce highly reliable, safe, and maintainable engineering products. Therefore, there is a definite need for the reliability, safety, and maintenance professionals to work closely during design and other phases. Engineering Systems Reliability, Safety, and Maintenance: An Integrated Approach eliminates the need to consult many different and diverse sources in the hunt for the information required to design better engineering systems.

Proven statistical reliability analysis methods—available for the first time to engineers in the West While probabilistic methods of system reliability analysis have reached an unparalleled degree of refinement, Russian engineers have concentrated on developing more advanced statistical methods.

Now Statistical Reliability Engineering affords engineers a unique opportunity to learn both the theory behind and applications of those statistical methods. Written by three leading innovators in the field, Statistical Reliability Engineering:

• Covers all mathematical models for statistical reliability analysis, including Bayesian estimation, accelerated testing, and Monte Carlo simulation
• Focuses on the estimation of various measures of system reliability based on the testing of individual units
• Contains new theoretical results available for the first time in print
• Features numerous examples demonstrating practical applications of the theory presented

The pilot study on Food Chain Security was launched in 2003 by NATO Public Diplomacy Division Science for Peace and Security Section (SPS) under the leadership of Turkey. The purpose of the study was to study the safety and security of food stuffs in the face of their careless/ignorant handling as well as against expected terrorist attacks at the system which may destroy and/or degrade it at the source during distribution, processing and in the consumption phase. The study included the protective and response measures which may have to be taken to reduce the risk and mitigate the consequences of these threats to the food system. The final outputs of this pilot study were agreed to be mainly: To allow comparison between country partners To identify common weaknesses of the food systems As a result of the terrible September 11, 2001 attacks in the United States the nature of the terrorist threat appears to be more uncertain and diffused, therefore the terrorist threat against the food system which comprises production, processing, distribution, restaurants, and retail can be very diverse and unpredictable and involve chemical, biological, and radiological agents of various kinds. Preparing for all possible contingencies was not practical, so a "risk management approach" was used in this study based on risk management principles that acknowledge while risk generally cannot be eliminated, enhancing protection from known or potential threats can reduce it.
