Book Synopsis Overview of risk-informed decision-making processes by : Enrico Zio
Download or read book Overview of risk-informed decision-making processes written by Enrico Zio and published by FonCSI. This book was released on 2012-10-01 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors introduce the general concepts, definitions and issues related to the use of Risk-informed decision-making (RIDM). These are structured processes which assist decision-makers when faced with high impact, complex decisions involving multiple objectives and the presence of uncertainty. They aim to ensure that decisions between competing alternatives are taken with an awareness of the risks associated with each option, and that all attributes of a decision are considered in an integrated manner. Motivations for the use of these techniques as a complement to more traditional deterministic approaches to risk assessment are provided. The RIDM processes adopted by NASA and by the US Nuclear Regulatory Commission are described in detail, with an analysis of commonalities and differences in approach.

Download or read book Integrated Risk-Informed Decision-Making for an ALMR PRISM. written by and published by . This book was released on 2016 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decision-making is the process of identifying decision alternatives, assessing those alternatives based on predefined metrics, selecting an alternative (i.e., making a decision), and then implementing that alternative. The generation of decisions requires a structured, coherent process, or a decision-making process. The overall objective for this work is that the generalized framework is adopted into an autonomous decision-making framework and tailored to specific requirements for various applications. In this context, automation is the use of computing resources to make decisions and implement a structured decision-making process with limited or no human intervention. The overriding goal of automation is to replace or supplement human decision makers with reconfigurable decision-making modules that can perform a given set of tasks rationally, consistently, and reliably. Risk-informed decision-making requires a probabilistic assessment of the likelihood of success given the status of the plant/systems and component health, and a deterministic assessment between plant operating parameters and reactor protection parameters to prevent unnecessary trips and challenges to plant safety systems. The probabilistic portion of the decision-making engine of the supervisory control system is based on the control actions associated with an ALMR PRISM. Newly incorporated into the probabilistic models are the prognostic/diagnostic models developed by Pacific Northwest National Laboratory. These allow decisions to incorporate the health of components into the decision-making process. Once the control options are identified and ranked based on the likelihood of success, the supervisory control system transmits the options to the deterministic portion of the platform. The deterministic portion of the decision-making engine uses thermal-hydraulic modeling and components for an advanced liquid-metal reactor Power Reactor Inherently Safe Module. The deterministic multi-attribute decision-making framework uses various sensor data (e.g., reactor outlet temperature, steam generator drum level) and calculates its position within the challenge state, its trajectory, and its margin within the controllable domain using utility functions to evaluate current and projected plant state space for different control decisions. The metrics that are evaluated are based on reactor trip set points. The integration of the deterministic calculations using multi-physics analyses and probabilistic safety calculations allows for the examination and quantification of margin recovery strategies. This also provides validation of the control options identified from the probabilistic assessment. Thus, the thermalhydraulics analyses are used to validate the control options identified from the probabilistic assessment. Future work includes evaluating other possible metrics and computational efficiencies, and developing a user interface to mimic display panels at a modern nuclear power plant.

Download or read book Science and Decisions written by National Research Council and published by National Academies Press. This book was released on 2009-03-24 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk assessment has become a dominant public policy tool for making choices, based on limited resources, to protect public health and the environment. It has been instrumental to the mission of the U.S. Environmental Protection Agency (EPA) as well as other federal agencies in evaluating public health concerns, informing regulatory and technological decisions, prioritizing research needs and funding, and in developing approaches for cost-benefit analysis. However, risk assessment is at a crossroads. Despite advances in the field, risk assessment faces a number of significant challenges including lengthy delays in making complex decisions; lack of data leading to significant uncertainty in risk assessments; and many chemicals in the marketplace that have not been evaluated and emerging agents requiring assessment. Science and Decisions makes practical scientific and technical recommendations to address these challenges. This book is a complement to the widely used 1983 National Academies book, Risk Assessment in the Federal Government (also known as the Red Book). The earlier book established a framework for the concepts and conduct of risk assessment that has been adopted by numerous expert committees, regulatory agencies, and public health institutions. The new book embeds these concepts within a broader framework for risk-based decision-making. Together, these are essential references for those working in the regulatory and public health fields.
Book Synopsis A Risk-informed Decision Making Framework Accounting for Early-phase Conceptual Design of Complex Systems by : Douglas L. Van Bossuyt
Download or read book A Risk-informed Decision Making Framework Accounting for Early-phase Conceptual Design of Complex Systems written by Douglas L. Van Bossuyt and published by . This book was released on 2012 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: A gap exists in the methods used in industry and available in academia that prevents customers and engineers from having a voice when considering engineering risk appetite in the dynamic shaping of early-phase conceptual design trade study outcomes. Current methods used in Collaborative Design Centers either collect risk information after a conceptual design has been created, treat risk as an afterthought during the trade study process, or do not consider risk at all during the creation of conceptual designs. This dissertation proposes a risk-informed decision making framework that offers a new way to account for risk and make decisions based upon risk information within conceptual complex system design trade studies. A meaningful integration of the consideration of risk in trade studies is achieved in this framework thus elevating risk to the same level as other important system-level design parameters. Trade-offs based upon risk appetites of individuals are explicitly allowed under the framework, enabled by an engineering-specific psychometric risk survey that provides aspirational information to use in utility functions. This dissertation provides a novel framework and supporting methodologies for risk-informed design decisions and trades to be made that are based upon engineering risk appetites in conceptual design trade studies.
Book Synopsis Confronting Climate Uncertainty in Water Resources Planning and Project Design by : Patrick A. Ray
Download or read book Confronting Climate Uncertainty in Water Resources Planning and Project Design written by Patrick A. Ray and published by World Bank Publications. This book was released on 2015-08-20 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Confronting Climate Uncertainty in Water Resources Planning and Project Design describes an approach to facing two fundamental and unavoidable issues brought about by climate change uncertainty in water resources planning and project design. The first is a risk assessment problem. The second relates to risk management. This book provides background on the risks relevant in water systems planning, the different approaches to scenario definition in water system planning, and an introduction to the decision-scaling methodology upon which the decision tree is based. The decision tree is described as a scientifically defensible, repeatable, direct and clear method for demonstrating the robustness of a project to climate change. While applicable to all water resources projects, it allocates effort to projects in a way that is consistent with their potential sensitivity to climate risk. The process was designed to be hierarchical, with different stages or phases of analysis triggered based on the findings of the previous phase. An application example is provided followed by a descriptions of some of the tools available for decision making under uncertainty and methods available for climate risk management. The tool was designed for the World Bank but can be applicable in other scenarios where similar challenges arise.
Book Synopsis Review of the Department of Homeland Security's Approach to Risk Analysis by : National Research Council

This book was released on 2010-10-10 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The events of September 11, 2001 changed perceptions, rearranged national priorities, and produced significant new government entities, including the U.S. Department of Homeland Security (DHS) created in 2003. While the principal mission of DHS is to lead efforts to secure the nation against those forces that wish to do harm, the department also has responsibilities in regard to preparation for and response to other hazards and disasters, such as floods, earthquakes, and other "natural" disasters. Whether in the context of preparedness, response or recovery from terrorism, illegal entry to the country, or natural disasters, DHS is committed to processes and methods that feature risk assessment as a critical component for making better-informed decisions. Review of the Department of Homeland Security's Approach to Risk Analysis explores how DHS is building its capabilities in risk analysis to inform decision making. The department uses risk analysis to inform decisions ranging from high-level policy choices to fine-scale protocols that guide the minute-by-minute actions of DHS employees. Although DHS is responsible for mitigating a range of threats, natural disasters, and pandemics, its risk analysis efforts are weighted heavily toward terrorism. In addition to assessing the capability of DHS risk analysis methods to support decision-making, the book evaluates the quality of the current approach to estimating risk and discusses how to improve current risk analysis procedures. Review of the Department of Homeland Security's Approach to Risk Analysis recommends that DHS continue to build its integrated risk management framework. It also suggests that the department improve the way models are developed and used and follow time-tested scientific practices, among other recommendations.

Book Synopsis Contributions to Risk-informed Decision Making by : Michael Alfred Elliott
Download or read book Contributions to Risk-informed Decision Making written by Michael Alfred Elliott and published by . This book was released on 2010 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk-informed decision-making (RIDM) is a formal process that assists stakeholders make decisions in the face of uncertainty. At MIT, a tool known as the Analytic Deliberative Decision Making Process (ADP) has been under development for a number of years to provide an efficient framework for implementing RIDM. ADP was initially developed as a tool to be used by a small group of stakeholders but now it has become desirable to extend ADP to an engineering scale that can be used by many individual across large organizations. This dissertation identifies and addresses four challenges in extended the ADP to an engineering scale. Rigorous preference elicitation using pairwise comparisons is addressed. A new method for judging numerical scales used in these comparisons is presented along with a new type of scale. This theory is tested by an experiment involving 64 individuals and it is found that the optimal scale is a matter of individual choice. The elicitation of expert opinion is studied and a process that adapts to the complexity of the decision at hand is proposed. This method is tested with a case study involving the choice of a heat removal technology for a new type of fission reactor. Issues related to the unique informational needs of large organizations are investigated and new tools to handle these needs are developed. Finally, difficulties with computationally intensive modeling and simulation are identified and a new method of uncertainty propagation using orthogonal polynomials is explored. Using a code designed to investigate the LOCA behavior of a fission reactor, it is demonstrated that this new propagation methods offers superior convergence over existing techniques.
Book Synopsis DHS Risk Lexicon by : Risk Steering Committee Homeland Security
Download or read book DHS Risk Lexicon written by Risk Steering Committee Homeland Security and published by . This book was released on 2008-09-01 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Homeland Security (DHS) is in the process of building an Integrated Risk Management Framework to improve its capability to make risk-informed strategic decisions using systematic and structured assessments of homeland security risk. The Integrated Risk Management Framework includes processes and tools that allow DHS to gather, integrate, analyze, and communicate information about risk such that it can be used to strategically prioritize efforts and resources throughout the DHS enterprise. The DHS Risk Lexicon supports the Integrated Risk Management Framework by defining a single language for DHS risk management. Clear and unambiguous communication amongst risk practitioners, decision makers, and homeland security stakeholders is a key aspect the Departments integrated risk management capability. The DHS Risk Lexicon represents a significant step forward by making available an official set of definitions for risk-related terms for the Department. The DHS Risk Lexicon is a product of the efforts of the Intra-Departmental DHS Risk Steering Committee (RSC). With membership from across the Department, the RSC was formed to leverage the risk management capabilities of DHS components, offices, and directorates to advance an integrated approach to risk management for DHS. The RSC has produced this DHS Risk Lexicon consisting of terms that are fundamental to the practice of homeland security risk management. The definitions in the DHS Risk Lexicon are intended to build a common vocabulary and language within the Department and enhance the ability of the DHS risk community to utilize risk information and assessments to set priorities for reducing the risks facing the Nation. The DHS Risk Lexicon is a dynamic document that will expand over time and be continually reviewed to ensure that terms and definitions are accurate and up to date. To more effectively execute its mission it is imperative that the Department, as a whole, adopts common definitions for risk-related terminology and makes every effort to use these common definitions in written and oral communication within and across its Components. I ask for your continued cooperation in adopting these terms and definitions, and ensuring that the DHS Risk Lexicon provides an enduring resource to improve our ability to manage homeland security risk.
Book Synopsis An Integrated Framework for the Next Generation of Risk-Informed Performance-Based Design Approach Used in Fire Safety Engineering by : Alberto Alvarez Rodriguez
Download or read book An Integrated Framework for the Next Generation of Risk-Informed Performance-Based Design Approach Used in Fire Safety Engineering written by Alberto Alvarez Rodriguez and published by . This book was released on 2012 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Review of decades of worldwide experience using standards, codes and guidelines related to performance-based fire protection design for buildings has identified shortcomings in the interpretation, application and implementation of the performance-based design process, wide variation in the resulting levels of performance achieved by such designs, and several opportunities to enhance the process. While others have highlighted shortcomings in the past, as well as some ideas to enhance the process, it is proposed that a more fundamental change is needed. First, the political and technical components of the process need to be clearly delineated to facilitate better analysis and decision-making within each component. Second, the process needs to be changed from one which focuses only on fire safety systems to one which views buildings, their occupants and their contents as integrated systems. In doing so, the activities associated with the normal operation of a building and how they might be impacted by the occurrence of a fire event become clearer, as do mitigation options which account for the behaviors and activities associated with normal use. To support these changes, a new framework for a risk-informed performance-based process for fire protection design is proposed: one which is better integrated than current processes, that treats a fire event as a disruptive event of a larger and more complex "building-occupant" system, and that provides more specific guidance for engineering analysis with the aim to achieve more complete and consistent analysis. This Ph. D. Dissertation outlines the challenges with the existing approaches, presents the "building-occupant" system paradigm, illustrates how viewing fire (or any other hazard) as a disruptive event within an holistic "building-occupant" system can benefit the overall performance of this system over its lifespan, and outlines a framework for a risk-informed performance-based process for fire protection design. Case studies are used to illustrate shortcomings in the existing processes and how the proposed process will address these. This Dissertation also includes a plan of action needed to establish guidelines to conduct each of the technical steps of the process and briefly introduces the future work about how this plan could be practically facilitated via a web-platform as a collaborative environment.
