This book was released on 1996-01-01 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study applies multi-attribute utility theory to the DOE's problem of selecting the least risky technologies to develop. It focuses on two aspects of the technical risks involved with emerging technologies: the risk of successful development (measured by the likelihood of successful R&D completion within seven years) and the risk of successful implementation in the field (measured by the likelihood of the technology performing as anticipated). Three experienced contractors working with the Landfill Stabilization Focus Area served in the roles of DOE technology managers. Their preferences, expressed as MAUT utility functions, were assessed for all seven functional remediation processes. These utilities are plotted as three-dimensional surfaces over a plane formed by the two technical risk measures, graphically depicting the trade-offs each 'decision maker' felt was appropriate between the two measures. Their utility surfaces for treatment technologies were then used with a set often treatment methods for which expert estimates of the two risk measures were available. The resulting rankings of technologies are analyzed to examine the suitability of the methodology. Recommendations for the use of this approach with real DOE managers are presented.

Download or read book Comparative Risk Assessment and Environmental Decision Making written by Igor Linkov and published by Springer Science & Business Media. This book was released on 2006-03-02 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decision making in environmental projects is typically a complex and confusing process characterized by trade-offs between socio-political, environmental, and economic impacts. Comparative Risk Assessment (CRA) is a methodology applied to facilitate decision making when various activities compete for limited resources. CRA has become an increasingly accepted research tool and has helped to characterize environmental profiles and priorities on the regional and national level. CRA may be considered as part of the more general but as yet quite academic field of multi-criteria decision analysis (MCDA). Considerable research in the area of MCDA has made available methods for applying scientific decision theoretical approaches to multi-criteria problems, but its applications, especially in environmental areas, are still limited. The papers show that the use of comparative risk assessment can provide the scientific basis for environmentally sound and cost-efficient policies, strategies, and solutions to our environmental challenges.

Download or read book Development of a Decision Support System for the Department of Energy s Selection of Waste Site Remediation Technologies written by Brian E. Ralston and published by . This book was released on 1996-03-01 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Energy is faced with the complex decision of selecting technologies for waste site remediation. This research focused on developing a decision support system to aid the decision maker in selecting the best strategy of remediation technologies. A decision analysis model was developed which incorporates life cycle cost data, risk information, and user input, to analyze the technology choices. The research outlined the use of multiple attribute utility theory using exponential attribute utility functions with a simple additive objective function. The best available data was used to demonstrate the capabilities of the model. The model provides the decision maker with estimates of the cost and time distributions, and the associated utility. Cumulative and frequency distributions illustrate the dominance of technology choices and the variance in the results. Cost and time plots allow the decision maker to see the trade offs inherent in the utility functions. The model also allows for sensitivity analysis in the form of rainbow and tornado diagrams to display the effects of changes in the values of the input variables. Overall, the model provides a generic technology selection tool that can be used to make better informed decisions and can be easily manipulated to reflect changes in the remediation process.

This book was released on 1997-03-01 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Energy is in the process of conducting a Remedial Investigation/Feasibility Study for a site contaminated with Dense Non-Aqueous Phase Liquid (DNAPL) pollutants at their Paducah Kentucky facility. A major part of this effort is the screening of alternative technologies. This thesis effort focuses on acquiring insight into a number of remediation technology trains that are candidates for the Paducah site. This insight is used to recommend and justify the screening of candidate technology trains. The research makes use of two decision analysis models (one is deterministic, the other is probabilistic) built to provide a quantitative assessment of the candidate technology trains. Dominance considerations and multi-attribute utility theory are utilized to make the quantitative assessments and to gain insight into each candidate technology train. The results of the analysis provide the DOE with a rational justification for screening 55 of the 58 candidate technology trains from further consideration. This represents a 95% reduction in the number of technology trains that are under consideration for remediating the Paducah site.

Download or read book A Risk Analysis of Remediation Technologies for a DOE Facility written by Helene A. Wilson and published by . This book was released on 1998-03-01 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Energy is responsible for selecting a remediation technology to cleanup the Waste Area Group (WAG) 6 site at the Paducah Gaseous Diffusion Plant (PGDP) in Kentucky. WAG 6 is contaminated with an uncertain amount of trichloroethylene (TCE) and technetium-99 (Tc-99). Selecting a remediation technology involves a certain degree of risk because many of these technologies are new or proven only for a specific type of contaminant or a particular set of site conditions. Differences between contaminant type and site conditions are enough to make the performance of a remediation technology uncertain. This research identifies the technological risks of two remediation technologies: Dynamic Underground Stripping (DUS) and In Situ Chemical Oxidation (ISCO). Risk is defined as the likelihood of undesirable events occurring during the implementation of a technology at WAG 6.

Available in PDF, EPUB and Kindle. Book excerpt: Decision analysis has become widely recognized as an important process for translating science into management actions. With climate change and other systemic threats as driving forces in creating environmental and engineering problems, there is a great need for understanding decision making frameworks through a case-study based approach. Management of environmental and engineering projects is often complicated and multidisciplinary in scope and nature, thus issues that arise can be difficult to solve analytically. Multi-Criteria Decision Analysis: Case Studies in Engineering and the Environment provides detailed description of MCDA methods and tools and illustrates their applications through case studies focused on sustainability and system engineering applications. New in the Second Edition: Addresses current and emerging environmental and engineering problems Includes seven new case studies to illustrate different management situations applicable at the international level Builds on real case studies from recent and relevant environmental and engineering management experience Describes advanced MCDA techniques and extensions used by practitioners Provides corresponding decision models implemented using the DECERNS software package Gives a more holistic approach to teaching MCDA methodology with a focus on sustainable solutions and adoption of new technologies, including nanotechnology and synthetic biology Given the novelty and inherent applicability of this decision-making framework to the environmental and engineering fields, a greater number of teaching tools for this topic need to be made available. This book provides those teaching tools, covering the breadth of the applications of MCDA methodologies with clear explanations of the MCDA process. The case studies are implemented in the DECERNS software package, allowing readers to experiment and explore and to understand the full process by which environmental managers assess these problems. This book is a great resource for professionals and students seeking to learn decision analysis techniques and apply similar frameworks to environmental and engineering projects

Download or read book Multiple Criteria Decision Analysis written by Valerie Belton and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of multiple criteria decision analysis (MCDA), also termed multiple criteria decision aid, or multiple criteria decision making (MCDM), has developed rapidly over the past quarter century and in the process a number of divergent schools of thought have emerged. This can make it difficult for a new entrant into the field to develop a comprehensive appreciation of the range of tools and approaches which are available to assist decision makers in dealing with the ever-present difficulties of seeking compromise or consensus between conflicting inter ests and goals, i.e. the "multiple criteria". The diversity of philosophies and models makes it equally difficult for potential users of MCDA, i.e. management scientists and/or decision makers facing problems involving conflicting goals, to gain a clear understanding of which methodologies are appropriate to their particular context. Our intention in writing this book has been to provide a compre hensive yet widely accessible overview of the main streams of thought within MCDA. We aim to provide readers with sufficient awareness of the underlying philosophies and theories, understanding of the practi cal details of the methods, and insight into practice to enable them to implement any of the approaches in an informed manner. As the title of the book indicates, our emphasis is on developing an integrated view of MCDA, which we perceive to incorporate both integration of differ ent schools of thought within MCDA, and integration of MCDA with broader management theory, science and practice.
