Book Description
One of the most valuable root-cause analysis tools in the system safety toolbox is fault tree analysis (FTA). A fault tree (FT) is a graphical diagram that uses logic gates to model the various combinations of failures, faults, errors and normal events involved in causing a specified undesired event to occur. The graphical model can be translated into a mathematical model in order to compute failure probabilities and system importance measures. A FT can model all aspects of a system, including hardware, software, human actions and the environment. FTs are employed to evaluate large complex and dynamic systems, in order to understand and prevent potential safety and reliability problems. Using the rigorous and structured methodology of FT construction allows the systems analyst to model the unique combinations of fault events that can cause an UE to occur. This book provides an overview of the FTA process; it describes the symbols, terms, construction methodology and mathematics of FTA.

Book Description
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. Design for Reliability was the first in the series with more planned for the future.

Book Description
Since 1975, a short course entitled "System Safety and Reliability Analysis" has been presented to over 200 NRC personnel and contractors. The course has been taught jointly by David F. Haasl, Institute of System Sciences, Professor Norman H. Roberts, University of Washington, and 'members of the Probabilistic Analysis Staff, NRC, as part of a risk assessment training program sponsored by the Probabilistic Analysis Staff. This handbook has been developed not only to serve as text for the System Safety and Reliability Course, but also to make available to others a set of otherwise undocumented material on fault tree construction and evaluation. The publication of this handbook is in accordance with the recommendations of the Risk Assessment Review Group Report (NUREG/CR-0400) in which it was stated that the fault/event tree methodology both can and should be used more widely by the NRC. It is hoped that this document will help to codify and systematize the fault tree approach to systems analysis.

Book Description
The importance of power system reliability is demonstrated when our electricity supply is disrupted, whether it decreases the comfort of our free time at home or causes the shutdown of our companies and results in huge economic deficits. The objective of Assessment of Power System Reliability is to contribute to the improvement of power system reliability. It consists of six parts divided into twenty chapters. The first part introduces the important background issues that affect power system reliability. The second part presents the reliability methods that are used for analyses of technical systems and processes. The third part discusses power flow analysis methods, because the dynamic aspect of a power system is an important part of related reliability assessments. The fourth part explores various aspects of the reliability assessment of power systems and their parts. The fifth part covers optimization methods. The sixth part looks at the application of reliability and optimization methods. Assessment of Power System Reliability has been written in straightforward language that continues into the mathematical representation of the methods. Power engineers and developers will appreciate the emphasis on practical usage, while researchers and advanced students will benefit from the simple examples that can facilitate their understanding of the theory behind power system reliability and that outline the procedure for application of the presented methods.
