فرایندهای ریسک قابل قبول: خطوط حیاتی و خطرات طبیعی

This report provides the vital tools engineers and decision makers need to better understand acceptable risk processes and how those processes can enable them to develop risk reduction strategies and implement mitigation actions to reduce lifeline losses from future earthquakes. Because the disruption of lifelines from natural hazards has a direct impact on the world’s regional economies and the health of its citizens, it is important to understand natural hazards, how they can impact lifelines, and what can be done to minimize the impact when they occur. These three elements and the processes used to act upon them affect decisions that involve acceptable risk processes. The topic of 'acceptable risk' provides one way of bringing integrated systems risk evaluations for disaster explicitly into a decision-making context. Topics include technical issues; risk criteria issues; and communication, administration, and regulations issues Degrees of Subjective Probability and Engineering Judgment artfully weaves together three elements at the very core of uncertainties in knowledge; inductive reasoning; and individual expertise. Written from a geotechnical and earth sciences perspective, it brings new meaning to these concepts for nearly any field of engineering, science, or technology decision making. It begins by examining the tension between theory and practice, showing how this is manifested in the different meanings of probability used in reliability and risk analysis. This book emphasizes the cognitive processes used in conceptualizing uncertainty, with techniques and tools for subjective probability assessment. Turning to what this requires, it lends substance to professional judgment by examining its diagnostic, inductive, and interpretive elements. It also investigates the nature of expertise by bringing to life such towering figures as Roebling, Stevens, and Terzaghi, and their monumental engineering achievements. Masterfully synthesizing a wide variety of sources in a way directly relevant to engineers, the book draws on the history and philosophy of science through the work of Thomas Kuhn and Henri Poincar. It provides a window on current behavioral research that applies it to everyday thinking. This is all richly illustrated by examples from practice, including a gripping reassessment of the 1986 Challenger incident as seen through the eyes of the engineers who experienced it. From philosophical foundations to nuts and bolts, this is a groundbreaking book of serious content and sparkling style sure to engage any engineer or scientist who thinks about what they do and how they do it.

When it comes to the planning, design, construction, and management of engineering systems, risk and uncertainty are unavoidable. The consideration of the risk involved in any situation, project, or plan becomes an integral part of the decision-making process. Risk and Reliability A Handbook for Civil and Environmental Engineers presents key concepts of risk and reliability that apply to a wide array of problems in civil and environmental engineering. The authors begin with an overview of the art of making decisions in the presence of uncertainty and then explain the fundamentals of probability that will be applied throughout the book. In the second part of the book, the authors discuss various techniques used in probability distributions and parameter estimation. A third section of the book considers different aspects of uncertainty analysis, especially risk analysis and risk management, providing instructive examples. The final group of chapters addresses reliability analysis and design, focusing particularly on the important area of water distribution networks. Ample illustrations and detailed real-life examples make Risk and Reliability Analysis essential reading for present and future engineers in the fields of civil, environmental, biological, and agricultural engineering, as well as the watershed sciences. The success of enterprises can often be attributed to their successful management of strategic risk. Conversely, failure to manage strategic risk can often lead to catastrophic consequences. Including a CD, this guide presents a recommended approach to the management of strategic risk, STRATrisk and an explanation of how to apply the approach."Reading this report will make company directors think hard - and few will decide to ignore its cogent and direct advice"--Dr Martin Barnes, Executive Director, The Major Projects Association and President, The Association for Project Management. The success of enterprises can often be attributed to their successful management of strategic risk. Conversely, failure to manage strategic risk can lead to often catastrophic consequences - Enron, Arthur Anderson, Kvaerner and Equitable Life were all seriously affected by a failure to think sufficiently about strategic risk. Most organisations have well embedded procedures for assessing and mitigating project and operational risks. Strategic risks are an order of magnitude greater and, by their very nature, involve a wider range of uncertainty and the interaction between a large number of factors, with major benefits accruing from managing them well and often dire consequences from the failure to manage them effectively Artificial Neural Network (ANN) technology is rarely used in water supply engineering. Those who have applied this technology for water supply engineering problems have reported findings that were beyond the capability of traditional statistical/mathematical modeling tools. The purpose of this task committee report is to compile the experiences of those who have successfully applied ANNs for water supply engineering problems and to reduce the perceived mystery of the ANN models. The availability of several diverse applications, along with the basics of neural network modeling, in a concise report are expected to encourage the use of this powerful technology. The report comprises several chapters summarizing experiences of individual groups of researchers around the world who demonstrated significant benefits of using neural network technology for diverse applications in water supply engineering. Some of the applications Forecasting salinity levels in River Murray, South Australia; Predicting gastroenteritis rates and waterborne outbreaks; Modeling pH levels in a eutrophic Middle Loire River, France; and ANNs as function approximation tools replacing rigorous mathematical simulation models for analyzing water distribution networks. Infrastructure Risk Management Processes: Natural, Accidental, and Deliberate Hazards, discusses quantification of exposure and vulnerability of complex, spatially distributed systems, yielding estimates of local and system-wide potential losses, for different alternatives in multi-hazard decision situations. These situations require an integration of scientific, engineering, social, administrative, psychological, and political processes - with advances, setbacks, and many uncertainties. This monograph consists of eight papers that illustrate work done to date and plans for work to be done on managing these risks for potable water, electric power, transportation and other infrastructure systems threatened by earthquakes, tsunamis, landslides, severe storms, saboteurs, and various other hazards. This monograph, produced by the Risk and Vulnerability Committee of the Council on Disaster Risk Management (CDRM), is a sequel to a previous monograph, Acceptable Risk Processes: Lifelines and Natural Hazards (2002), published by ASCE. Topics include:
* Hazard Issues
* Systems Evaluation Issues
* Risk Criteria Issues
* Systems Management Issues.

Among the practical steps recommended are: examination of the key processes already embedded in the organisation to see whether they contain hidden strategic risks; adequate follow-through from risk identification; and, the use of tools such as horizon scanning, concept mapping, pattern recognition and risk grouping. The CD amplifies the information contained in the printed guide and provides video clips and a number of case studies. "I thoroughly recommend it"--Lord Broers, President of the Royal Academy of Engineering This book explores how the dualities of thinking in engineering and science are manifested in probability and risk analysis, professional judgment, and the nature of expertise. Written from a geotechnical perspective, these topics are woven into professional practice through examples and case studies, and through the lives, careers, and lasting achievements of some legendary civil engineering experts. By examining the cognitive process that underlie the whole of engineering, this work brings new substance to engineering judgment, showing in the process how probability, judgmemnt, and expertise are inextricably linked as indispensable elements of professional practice, and indeed of thinking itself.

Engineers must be aware of methods to operate in ambiguous situations. Project promoters, project managers and consultants should understand the formative stages of each project and the risk and value decisions that have to be made. This book offers one of the first integrated approaches to these three topics based on the views of experts in these disciplines.
