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
A practical guide to identifying hazards using common hazard analysis techniques Many different hazard analysis techniques have been developed over the past forty years. However, there is only a handful of techniques that safety analysts actually apply in their daily work. Written by a former president of the System Safety Society and winner of the Boeing Achievement and Apollo Awards for his safety analysis work, Hazard Analysis Techniques for System Safety explains, in detail, how to perform the most commonly used hazard analysis techniques employed by the system safety engineering discipline. Focusing on the twenty-two most commonly used hazard analysis methodologies in the system safety discipline, author Clifton Ericson outlines the three components that comprise a hazard and describes how to use these components to recognize a hazard during analysis. He then examines each technique in sufficient detail and with numerous illustrations and examples, to enable the reader to easily understand and perform the analysis. Techniques covered include: * Preliminary Hazard List (PHL) Analysis * Preliminary Hazard Analysis (PHA) * Subsystem Hazard Analysis (SSHA) * System Hazard Analysis (SHA) * Operating and Support Hazard Analysis (O&SHA) * Health Hazard Assessment (HHA) * Safety Requirements/Criteria Analysis (SRCA) * Fault Tree Analysis (FTA) * Event Tree Analysis (ETA) * Failure Mode and Effects Analysis (FMEA) * Fault Hazard Analysis * Functional Hazard Analysis * Sneak Circuit Analysis (SCA) * Petri Net Analysis (PNA) * Markov Analysis (MA) * Barrier Analysis (BA) * Bent Pin Analysis (BPA) * HAZOP Analysis * Cause Consequence Analysis (CCA) * Common Cause Failure Analysis (CCFA) * MORT Analysis * Software Safety Assessment (SWSA) Written to be accessible to readers with a minimal amount of technical background, Hazard Analysis Techniques for System Safety gathers, for the first time in one source, the techniques that safety analysts actually apply in daily practice. Both new and seasoned analysts will find this book an invaluable resource for designing and constructing safe systems-- in short, for saving lives.

Book Description
Complex mathematical and computational models are used in all areas of society and technology and yet model based science is increasingly contested or refuted, especially when models are applied to controversial themes in domains such as health, the environment or the economy. More stringent standards of proofs are demanded from model-based numbers, especially when these numbers represent potential financial losses, threats to human health or the state of the environment. Quantitative sensitivity analysis is generally agreed to be one such standard. Mathematical models are good at mapping assumptions into inferences. A modeller makes assumptions about laws pertaining to the system, about its status and a plethora of other, often arcane, system variables and internal model settings. To what extent can we rely on the model-based inference when most of these assumptions are fraught with uncertainties? Global Sensitivity Analysis offers an accessible treatment of such problems via quantitative sensitivity analysis, beginning with the first principles and guiding the reader through the full range of recommended practices with a rich set of solved exercises. The text explains the motivation for sensitivity analysis, reviews the required statistical concepts, and provides a guide to potential applications. The book: Provides a self-contained treatment of the subject, allowing readers to learn and practice global sensitivity analysis without further materials. Presents ways to frame the analysis, interpret its results, and avoid potential pitfalls. Features numerous exercises and solved problems to help illustrate the applications. Is authored by leading sensitivity analysis practitioners, combining a range of disciplinary backgrounds. Postgraduate students and practitioners in a wide range of subjects, including statistics, mathematics, engineering, physics, chemistry, environmental sciences, biology, toxicology, actuarial sciences, and econometrics will find much of use here. This book will prove equally valuable to engineers working on risk analysis and to financial analysts concerned with pricing and hedging.
