| fault tree analysis example: Poverty in the Philippines Asian Development Bank, 2009-12-01 Against the backdrop of the global financial crisis and rising food, fuel, and commodity prices, addressing poverty and inequality in the Philippines remains a challenge. The proportion of households living below the official poverty line has declined slowly and unevenly in the past four decades, and poverty reduction has been much slower than in neighboring countries such as the People's Republic of China, Indonesia, Thailand, and Viet Nam. Economic growth has gone through boom and bust cycles, and recent episodes of moderate economic expansion have had limited impact on the poor. Great inequality across income brackets, regions, and sectors, as well as unmanaged population growth, are considered some of the key factors constraining poverty reduction efforts. This publication analyzes the causes of poverty and recommends ways to accelerate poverty reduction and achieve more inclusive growth. it also provides an overview of current government responses, strategies, and achievements in the fight against poverty and identifies and prioritizes future needs and interventions. The analysis is based on current literature and the latest available data, including the 2006 Family Income and Expenditure Survey. |

| fault tree analysis example: The Dictionary of Obscure Sorrows John Koenig, 2021-11-16 NEW YORK TIMES BESTSELLER “It’s undeniably thrilling to find words for our strangest feelings…Koenig casts light into lonely corners of human experience…An enchanting book. “ —The Washington Post A truly original book in every sense of the word, The Dictionary of Obscure Sorrows poetically defines emotions that we all feel but don’t have the words to express—until now. Have you ever wondered about the lives of each person you pass on the street, realizing that everyone is the main character in their own story, each living a life as vivid and complex as your own? That feeling has a name: “sonder.” Or maybe you’ve watched a thunderstorm roll in and felt a primal hunger for disaster, hoping it would shake up your life. That’s called “lachesism.” Or you were looking through old photos and felt a pang of nostalgia for a time you’ve never actually experienced. That’s “anemoia.” If you’ve never heard of these terms before, that’s because they didn’t exist until John Koenig set out to fill the gaps in our language of emotion. The Dictionary of Obscure Sorrows “creates beautiful new words that we need but do not yet have,” says John Green, bestselling author of The Fault in Our Stars. By turns poignant, relatable, and mind-bending, the definitions include whimsical etymologies drawn from languages around the world, interspersed with otherworldly collages and lyrical essays that explore forgotten corners of the human condition—from “astrophe,” the longing to explore beyond the planet Earth, to “zenosyne,” the sense that time keeps getting faster. The Dictionary of Obscure Sorrows is for anyone who enjoys a shift in perspective, pondering the ineffable feelings that make up our lives. With a gorgeous package and beautiful illustrations throughout, this is the perfect gift for creatives, word nerds, and human beings everywhere. |

| fault tree analysis example: The Reliability, Availability and Productiveness of Systems D.J. Sherwin, A. Bossche, 2012-11-16 This book is about the measurement and prediction of the reliability behaviour of systems of physical items. It is not specifically concerned with human factors with safety analysis as such, although some of the techniques discussed are adaptable to these purposes. A machine or an electronic circuit exemplifies a system. Each machine or circuit may also be treated as an item in a larger system. However, this does not reduce it suddenly to basic component status; it remains complex and can only be treated as unitary under definable restrictions. In particular, the effects of maintenance and component renewal must be considered most carefully. Previous books on system reliability have concentrated on one or two only of the six principal techniques available to the analyst. These are: 1. probability theory; 2. distributional statistics; 3. markov methods (matrix algebra); 4. fault and event trees (Boolean logic); 5. theory of renewal processes; 6. directional graph theory (di-graphs). This book relates these methods to one another and to their applications. The authors feel that previous books which concentrated upon one tech nique and the contortions necessary to use it in every possible situation may have misled readers into believing that there were no other methods and that some real problems were intractable or more difficult to solve than need be. For example, several results which are proved in other books for items with exponentially distributed times to/between failures are shown to be independent of distribution. |

| fault tree analysis example: How to Organize and Run a Failure Investigation Daniel P. Dennies, 2005 Learning the proper steps for organizing a failure investigation ensures success. Failure investigations cross company functional boundaries and are an integral component of any design or manufacturing business operation. Well-organized and professionally conducted investigations are essential for solving manufacturing problems and assisting in redesigns. This book outlines a proven systematic approach to failure investigation. It explains the relationship between various failure sources (corrosion, for example) and the organization and conduct of the investigation. It provides a learning platform for engineers from all disciplines: materials, design, manufacturing, quality, and management. The examples in this book focus on the definition of and requirements for a professionally performed failure analysis of a physical object or structure. However, many of the concepts have much greater utility than for investigating the failure of physical objects. For example, the book provides guidance in areas such as learning how to define objectives, negotiating the scope of investigation, examining the physical evidence, and applying general problem-solving techniques. |
| fault tree analysis example: Fault Tree Analysis Primer Clifton A.. Ericson, 2011-12-15 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. |
| fault tree analysis example: Words of Radiance Brandon Sanderson, 2014-03-04 From #1 New York Times bestselling author Brandon Sanderson, Words of Radiance, Book Two of the Stormlight Archive, continues the immersive fantasy epic that The Way of Kings began. Expected by his enemies to die the miserable death of a military slave, Kaladin survived to be given command of the royal bodyguards, a controversial first for a low-status darkeyes. Now he must protect the king and Dalinar from every common peril as well as the distinctly uncommon threat of the Assassin, all while secretly struggling to master remarkable new powers that are somehow linked to his honorspren, Syl. The Assassin, Szeth, is active again, murdering rulers all over the world of Roshar, using his baffling powers to thwart every bodyguard and elude all pursuers. Among his prime targets is Highprince Dalinar, widely considered the power behind the Alethi throne. His leading role in the war would seem reason enough, but the Assassin's master has much deeper motives. Brilliant but troubled Shallan strives along a parallel path. Despite being broken in ways she refuses to acknowledge, she bears a terrible burden: to somehow prevent the return of the legendary Voidbringers and the civilization-ending Desolation that will follow. The secrets she needs can be found at the Shattered Plains, but just arriving there proves more difficult than she could have imagined. Meanwhile, at the heart of the Shattered Plains, the Parshendi are making an epochal decision. Hard pressed by years of Alethi attacks, their numbers ever shrinking, they are convinced by their war leader, Eshonai, to risk everything on a desperate gamble with the very supernatural forces they once fled. The possible consequences for Parshendi and humans alike, indeed, for Roshar itself, are as dangerous as they are incalculable.

| fault tree analysis example: Learning from Failures Ashraf Labib, 2014-06-19 Learning from Failures provides techniques to explore the root causes of specific disasters and how we can learn from them. It focuses on a number of well-known case studies, including: the sinking of the Titanic; the BP Texas City incident; the Chernobyl disaster; the NASA Space Shuttle Columbia accident; the Bhopal disaster; and the Concorde accident. This title is an ideal teaching aid, informed by the author's extensive teaching and practical experience and including a list of learning outcomes at the beginning of each chapter, detailed derivation, and many solved examples for modeling and decision analysis. This book discusses the value in applying different models as mental maps to analyze disasters. The analysis of these case studies helps to demonstrate how subjectivity that relies on opinions of experts can be turned into modeling approaches that can ensure repeatability and consistency of results. The book explains how the lessons learned by studying these individual cases can be applied to a wide range of industries. This work is an ideal resource for undergraduate and postgraduate students, and will also be useful for industry professionals who wish to avoid repeating mistakes that resulted in devastating consequences. - Explores the root cause of disasters and various preventative measures - Links theory with practice in regard to risk, safety, and reliability analyses - Uses analytical techniques originating from reliability analysis of equipment failures, multiple criteria decision making, and artificial intelligence domains |
| fault tree analysis example: Reliability Growth Panel on Reliability Growth Methods for Defense Systems, Committee on National Statistics, Division of Behavioral and Social Science, Division of Behavioral and Social Sciences and Education, National Research Council, 2015-03-01 A high percentage of defense systems fail to meet their reliability requirements. This is a serious problem for the U.S. Department of Defense (DOD), as well as the nation. Those systems are not only less likely to successfully carry out their intended missions, but they also could endanger the lives of the operators. Furthermore, reliability failures discovered after deployment can result in costly and strategic delays and the need for expensive redesign, which often limits the tactical situations in which the system can be used. Finally, systems that fail to meet their reliability requirements are much more likely to need additional scheduled and unscheduled maintenance and to need more spare parts and possibly replacement systems, all of which can substantially increase the life-cycle costs of a system. Beginning in 2008, DOD undertook a concerted effort to raise the priority of reliability through greater use of design for reliability techniques, reliability growth testing, and formal reliability growth modeling, by both the contractors and DOD units. To this end, handbooks, guidances, and formal memoranda were revised or newly issued to reduce the frequency of reliability deficiencies for defense systems in operational testing and the effects of those deficiencies. Reliability Growth evaluates these recent changes and, more generally, assesses how current DOD principles and practices could be modified to increase the likelihood that defense systems will satisfy their reliability requirements. This report examines changes to the reliability requirements for proposed systems; defines modern design and testing for reliability; discusses the contractor's role in reliability testing; and summarizes the current state of formal reliability growth modeling. The recommendations of Reliability Growth will improve the reliability of defense systems and protect the health of the valuable personnel who operate them. |
