Download or read book Subjective Probability Distribution Elicitation in Cost Risk Analysis written by Lionel A. Galway and published by Rand Corporation. This book was released on 2007 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: A cost estimate for a project such as the acquisition of a new aircraft or satellite system carries with it an inherent probability that the actual cost will exceed the estimate-that changes in requirements, technology, the economic environment, and a multitude of other factors that may occur over the life of the project will change the final cost. One major approach to cost risk analysis-the evaluating and quantifying of the uncertainty of a cost estimate-has been probabilistic: expressing the uncertainty in a cost estimate as a probability distribution over a range of potential costs. Cost analysts in industry and government and researchers in statistics and management have often proposed that, to get probability distributions for platforms using new and untried technologies, expert judgment should be tapped and subjective probability distributions elicited from the experts to represent cost uncertainty. This technical report reviews procedures for eliciting subjective probability distributions in cost risk analysis, both in the cost risk field and in other disciplines in which elicitation has been a topic of research-primarily, statistics and psychology. Because of a lack of empirical work in elicitation, especially in cost risk, the author also interviewed a number of senior people in the cost risk community, who gave insight into the practices of the field. This report should be of interest to cost analysis professionals who wish to quantify uncertainty when using expert opinions in cost risk analysis.

Available in PDF, EPUB and Kindle. Book excerpt: Explores methods for the representation and treatment of uncertainty in risk assessment In providing guidance for practical decision-making situations concerning high-consequence technologies (e.g., nuclear, oil and gas, transport, etc.), the theories and methods studied in Uncertainty in Risk Assessment have wide-ranging applications from engineering and medicine to environmental impacts and natural disasters, security, and financial risk management. The main focus, however, is on engineering applications. While requiring some fundamental background in risk assessment, as well as a basic knowledge of probability theory and statistics, Uncertainty in Risk Assessment can be read profitably by a broad audience of professionals in the field, including researchers and graduate students on courses within risk analysis, statistics, engineering, and the physical sciences. Uncertainty in Risk Assessment: Illustrates the need for seeing beyond probability to represent uncertainties in risk assessment contexts. Provides simple explanations (supported by straightforward numerical examples) of the meaning of different types of probabilities, including interval probabilities, and the fundamentals of possibility theory and evidence theory. Offers guidance on when to use probability and when to use an alternative representation of uncertainty. Presents and discusses methods for the representation and characterization of uncertainty in risk assessment. Uses examples to clearly illustrate ideas and concepts.

Download or read book Cost Analysis and Estimating written by Willis R., Jr. Greer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changes in production processes reflect the technological advances permeat ing our products and services. U. S. industry is modernizing and automating. In parallel, direct labor is fading as the primary cost driver while engineering and technology related cost elements loom ever larger. Traditional, labor-based ap proaches to estimating costs are losing their relevance. Old methods require aug mentation with new estimating tools and techniques that capture the emerging environment. This volume represents one of many responses to this challenge by the cost analysis profession. The Institute of Cost Analysis (lCA) is dedicated to improving the effective ness of cost and price analysis and enhancing the professional competence of its members. We encourage and promote exchange of research findings and appli cations between the academic community and cost professionals in industry and government. The 1990 National Meeting in Los Angeles, jointly spo~sored by ICA and the National Estimating Society (NES), provides such a forum. Presen tations will focus on new and improved tools and techniques of cost analysis. This volume is the second in a series. The first was produced in conjunction with the 1989 National Meeting of ICA/NES in Washington, D.C. The articles in this volume, all refereed, were selected from about 100 submitted for presen tation at the Los Angeles meeting.

Download or read book Science and Judgment in Risk Assessment written by National Research Council and published by National Academies Press. This book was released on 1994-01-01 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: The public depends on competent risk assessment from the federal government and the scientific community to grapple with the threat of pollution. When risk reports turn out to be overblownâ€"or when risks are overlookedâ€"public skepticism abounds. This comprehensive and readable book explores how the U.S. Environmental Protection Agency (EPA) can improve its risk assessment practices, with a focus on implementation of the 1990 Clean Air Act Amendments. With a wealth of detailed information, pertinent examples, and revealing analysis, the volume explores the "default option" and other basic concepts. It offers two views of EPA operations: The first examines how EPA currently assesses exposure to hazardous air pollutants, evaluates the toxicity of a substance, and characterizes the risk to the public. The second, more holistic, view explores how EPA can improve in several critical areas of risk assessment by focusing on cross-cutting themes and incorporating more scientific judgment. This comprehensive volume will be important to the EPA and other agencies, risk managers, environmental advocates, scientists, faculty, students, and concerned individuals.

Download or read book Systems Lifecycle Cost Effectiveness written by Massimo Pica and published by Routledge. This book was released on 2016-04-01 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditional costing models for new systems and new buildings in industry, defence or government, have tended to focus on the costs of acquisition and implementation, with scant regard for the costs of running the system or decommissioning after use. The pressure to minimize expenditure and provide value for money from reduced resources means that complex projects have to encompass a wide range of often conflicting issues and interests. Systems Lifecycle Cost-Effectiveness shows how to manage the difficulties that can arise. Optimizing the system lifecycle cost-effectiveness is complex and influenced by many factors. Massimo Pica presents a variety of models for calculating cost, benefits and risk in projects, and explains how the human factors associated with a system’s design and consequent value are as important as the technical costs associated with its construction or creation. This comprehensive text can be used by students, experienced system engineers, cost analysts and managers to improve their understanding of the wide range of issues involved in the evaluation of system life cycle cost-effectiveness.

Download or read book Beyond Beta written by Samuel Kotz and published by World Scientific. This book was released on 2004 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Statistical distributions are fundamental to Statistical Science and are a prime indispensable tool for its applications. This monograph is the first to examine an important but somewhat neglected field — univariate continuous distribution on a bounded domain, excluding the beta distribution. It provides an elementary but thorough discussion of “novel” contributions developed in recent years, such as the two-sided power, generalized trapezoidal and generalized Topp and Leone distributions, among others. It discusses a general framework for constructing two-sided distributions and some of its properties. It contains a comprehensive chapter on the triangular distribution as well as a chapter on earlier extensions not emphasized in existing literature. Special attention is given to estimation, in particular, non-standard maximum likelihood procedures. The applications are drawn mainly from the econometric and engineering domains.
