Book Synopsis Defense Modeling, Simulation, and Analysis by : National Research Council
Download or read book Defense Modeling, Simulation, and Analysis written by National Research Council and published by National Academies Press. This book was released on 2006-09-22 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modeling, simulation, and analysis (MS&A) is a crucial tool for military affairs. MS&A is one of the announced pillars of a strategy for transforming the U.S. military. Yet changes in the enterprise of MS&A have not kept pace with the new demands arising from rapid changes in DOD processes and missions or with the rapid changes in the technology available to meet those demands. To help address those concerns, DOD asked the NRC to identify shortcomings in current practice of MS&A and suggest where and how they should be resolved. This report provides an assessment of the changing mission of DOD and environment in which it must operate, an identification of high-level opportunities for MS&A research to address the expanded mission, approaches for improving the interface between MS&A practitioners and decision makers, a discussion of training and continuing education of MS&A practitioners, and an examination of the need for coordinated military science research to support MS&A.

Book excerpt: An insightful presentation of the key concepts, paradigms, and applications of modeling and simulation Modeling and simulation has become an integral part of research and development across many fields of study, having evolved from a tool to a discipline in less than two decades. Modeling and Simulation Fundamentals offers a comprehensive and authoritative treatment of the topic and includes definitions, paradigms, and applications to equip readers with the skills needed to work successfully as developers and users of modeling and simulation. Featuring contributions written by leading experts in the field, the book's fluid presentation builds from topic to topic and provides the foundation and theoretical underpinnings of modeling and simulation. First, an introduction to the topic is presented, including related terminology, examples of model development, and various domains of modeling and simulation. Subsequent chapters develop the necessary mathematical background needed to understand modeling and simulation topics, model types, and the importance of visualization. In addition, Monte Carlo simulation, continuous simulation, and discrete event simulation are thoroughly discussed, all of which are significant to a complete understanding of modeling and simulation. The book also features chapters that outline sophisticated methodologies, verification and validation, and the importance of interoperability. A related FTP site features color representations of the book's numerous figures. Modeling and Simulation Fundamentals encompasses a comprehensive study of the discipline and is an excellent book for modeling and simulation courses at the upper-undergraduate and graduate levels. It is also a valuable reference for researchers and practitioners in the fields of computational statistics, engineering, and computer science who use statistical modeling techniques.
Book Synopsis Defense Modeling and Simulation by :
Download or read book Defense Modeling and Simulation written by and published by . This book was released on 1996 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: I believe this industry day is timely because the Department of Defense, through adoption of a Modeling and Simulation Master Plan in October of 1995, has begun to move forward on a more coherent strategy for improving oversight and coordination of DoD modeling and simulation activities. In a budget constrained environment, we simply can not afford to waste dollars on redundant, stove-piped efforts - we need to be able to get more mileage out of the models and simulations we build. In an environment that is increasingly joint, often coalition, and involving system of systems architectural trades, we must be able to link simulations together and interoperate them in federations. To do that we have to find ways to facilitate their interoperability and reusability. DoD modeling and simulation activities need to be anchored in a common technical architecture and interchange data which is both authoritative and means the same thing to everyone. For the remainder of my talk today, I would like to give you the Department's perspective on the use of modeling and simulation to improve training, decision support and weapon system acquisition.

Book Synopsis The Prospects for Increasing the Reuse of Digital Training Content by : Michael G. Shanley
Download or read book The Prospects for Increasing the Reuse of Digital Training Content written by Michael G. Shanley and published by Rand Corporation. This book was released on 2009 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: "RAND was asked to examine how the Advanced Distributed Learning (ADL) Initiative and the Department of Defense (DoD) more broadly might encourage the reuse of digital training content as a strategy to reduce the cost of its development. The study focused primarily on the extent to which incentives and other enablers currently are and might be used to encourage training development (TD) organizations to develop a reuse mechanism, especially one supported by repositories. Data on existing efforts to reuse digital training content were gathered from the defense, commercial, and academic sectors through semi-structured telephone interviews and site visits at large TD organizations. In addition, studies on incentive issues in the knowledge management literature and reuse efforts in the domains of software and materiel development were reviewed. Five currently used reuse strategies were identified and assessed, with the greatest emphasis on the production of reusable learning objects (RLOs) to be stored in large, searchable learning object repositories accessible to multiple organizations. Findings highlighted a number of challenges in current reuse efforts -- for example, low rates of return on many investments in reuse, technical challenges with the RLO strategy that will take time to overcome, and the need to develop implementation processes for RLO reuse, including those that address disincentives to sharing within and among organizations. The study also concluded that ADL can encourage the reuse option by taking a proactive approach in supporting organizations attempting to implement a reuse strategy. For example, ADL might broaden definitions of reuse and redefine success via the use of metrics and surveys, invest in high-profile pilots and other research to identify conditions with the highest potential payoffs for reuse, and evolve its role as a trusted advisor to organizations seeking guidance on implementation." -- provided by publisher.

Book Synopsis Behavioral Modeling and Simulation by : National Research Council
Download or read book Behavioral Modeling and Simulation written by National Research Council and published by National Academies Press. This book was released on 2008-07-04 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today's military missions have shifted away from fighting nation states using conventional weapons toward combating insurgents and terrorist networks in a battlespace in which the attitudes and behaviors of civilian noncombatants may be the primary effects of military actions. To support these new missions, the military services are increasingly interested in using models of the behavior of humans, as individuals and in groups of various kinds and sizes. Behavioral Modeling and Simulation reviews relevant individual, organizational, and societal (IOS) modeling research programs, evaluates the strengths and weaknesses of the programs and their methodologies, determines which have the greatest potential for military use, and provides guidance for the design of a research program to effectively foster the development of IOS models useful to the military. This book will be of interest to model developers, operational military users of the models and their managers, and government personnel making funding decisions regarding model development.
Book Synopsis Estimating Impact by : Alexander Kott
Download or read book Estimating Impact written by Alexander Kott and published by Springer Science & Business Media. This book was released on 2010-09-15 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sociological theories of crime include: theories of strain blame crime on personal stressors; theories of social learning blame crime on its social rewards, and see crime more as an institution in conflict with other institutions rather than as in- vidual deviance; and theories of control look at crime as natural and rewarding, and explore the formation of institutions that control crime. Theorists of corruption generally agree that corruption is an expression of the Patron–Client relationship in which a person with access to resources trades resources with kin and members of the community in exchange for loyalty. Some approaches to modeling crime and corruption do not involve an explicit simulation: rule based systems; Bayesian networks; game theoretic approaches, often based on rational choice theory; and Neoclassical Econometrics, a rational choice-based approach. Simulation-based approaches take into account greater complexities of interacting parts of social phenomena. These include fuzzy cognitive maps and fuzzy rule sets that may incorporate feedback; and agent-based simulation, which can go a step farther by computing new social structures not previously identified in theory. The latter include cognitive agent models, in which agents learn how to perceive their en- ronment and act upon the perceptions of their individual experiences; and reactive agent simulation, which, while less capable than cognitive-agent simulation, is adequate for testing a policy’s effects with existing societal structures. For example, NNL is a cognitive agent model based on the REPAST Simphony toolkit.
Book Synopsis Working Through Synthetic Worlds by : Kenneth W. Kisiel
Download or read book Working Through Synthetic Worlds written by Kenneth W. Kisiel and published by CRC Press. This book was released on 2018-04-17 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Virtual environments (VE) are human-computer interfaces in which the computer creates a sensory-immersing environment that interactively responds to and is controlled by the behaviour of the user. Since these technologies will continue to become more reliable, more resolute and more affordable, it's important to consider the advantages that VEs may offer to support business processes. The term 'synthetic world' refers to a subset of VEs, having a large virtual landscape and a set of rules that govern the interactions among participants. Currently, the primary motivators for participation in these synthetic worlds appear to be fun and novelty. As the novelty wears off, synthetic worlds will need to demonstrate a favourable value proposition if they are to survive. In particular, non-game-oriented worlds will need to facilitate business processes to a degree that exceeds their substantial costs for development and maintenance. Working Through Synthetic Worlds explores a variety of different tasks that might benefit by being performed within a synthetic world. The editors use a distinctive format for the book, consisting of a set of chapters composed of three parts: ¢ a story or vignette that describes work conducted within a synthetic world based loosely on the question, 'what will work be like in the year 2025?', founded on the expert authors' expectations of plausible future technologies ¢ a scholarly review of the technologies described by the stories and the current theories related to those technologies ¢ a prescription for future research required to bridge the current state-of-the-art with the notional worlds described in the stories. The book will appeal to undergraduate and graduate students, professors, scientists and engineers, managers in high-tech industries and software developers.

Book Synopsis AI Enabled Business by : Melodena Stephens
Download or read book AI Enabled Business written by Melodena Stephens and published by IAP. This book was released on 2023-07-01 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the use of AI becomes more and more ubiquitous in companies around the world, managers charged with taking key decisions require resources to enable them to evaluate new projects effectively. The business case for AI projects is not necessarily clear cut and part of the reason for this is the lack of understanding on key decision criteria. AI touches on many ethical concepts - data privacy, validity and more importantly, its potential misuse. AI is often being used to replace human decision-making and there is often no real understanding of the implications of this. This book provides a detailed primer for practitioners without a deep technological background. It guides the reader through the basic issues and offers advice on ‘how to take decisions’. There is a dearth of such books currently available and this book aspires to fill a growing niche. ENDORSEMENTS: "This book is sure to offer value to business users, students and the general public." — K. Ananth Krishnan, Tata Consultancy Services "I highly recommend this book for the leader seeking an up-to-date review of AI to make strategic investments." — Kes Sampanthar, Innovation, BCG Brighthouse "The specificity of application in case studies and easy to understand definitions and recommendations make this a must read in the ever-growing field of literature around AI." — John C. Havens "The AI Enabled Organization is the perfect tool to embark on a thorough assessment of what AI means for your business." — Arno Fehler, Schmidt Kranz Group, Germany
Book Synopsis Social-Behavioral Modeling for Complex Systems by : Paul K. Davis
Download or read book Social-Behavioral Modeling for Complex Systems written by Paul K. Davis and published by John Wiley & Sons. This book was released on 2019-04-09 with total page 992 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume describes frontiers in social-behavioral modeling for contexts as diverse as national security, health, and on-line social gaming. Recent scientific and technological advances have created exciting opportunities for such improvements. However, the book also identifies crucial scientific, ethical, and cultural challenges to be met if social-behavioral modeling is to achieve its potential. Doing so will require new methods, data sources, and technology. The volume discusses these, including those needed to achieve and maintain high standards of ethics and privacy. The result should be a new generation of modeling that will advance science and, separately, aid decision-making on major social and security-related subjects despite the myriad uncertainties and complexities of social phenomena. Intended to be relatively comprehensive in scope, the volume balances theory-driven, data-driven, and hybrid approaches. The latter may be rapidly iterative, as when artificial-intelligence methods are coupled with theory-driven insights to build models that are sound, comprehensible and usable in new situations. With the intent of being a milestone document that sketches a research agenda for the next decade, the volume draws on the wisdom, ideas and suggestions of many noted researchers who draw in turn from anthropology, communications, complexity science, computer science, defense planning, economics, engineering, health systems, medicine, neuroscience, physics, political science, psychology, public policy and sociology. In brief, the volume discusses: Cutting-edge challenges and opportunities in modeling for social and behavioral science Special requirements for achieving high standards of privacy and ethics New approaches for developing theory while exploiting both empirical and computational data Issues of reproducibility, communication, explanation, and validation Special requirements for models intended to inform decision making about complex social systems
Book Synopsis Engineering Emergence by : Larry B. Rainey
Download or read book Engineering Emergence written by Larry B. Rainey and published by CRC Press. This book was released on 2018-09-03 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the nature of emergence in context of man-made (i.e. engineered) systems, in general, and system of systems engineering applications, specifically. It investigates emergence to interrogate or explore the domain space from a modeling and simulation perspective to facilitate understanding, detection, classification, prediction, control, and visualization of the phenomenon. Written by leading international experts, the text is the first to address emergence from an engineering perspective. "System engineering has a long and proud tradition of establishing the integrative view of systems. The field, however, has not always embraced and assimilated well the lessons and implications from research on complex adaptive systems. As the editors’ note, there have been no texts on Engineering Emergence: Principles and Applications. It is therefore especially useful to have this new, edited book that pulls together so many of the key elements, ranging from the theoretical to the practical, and tapping into advances in methods, tools, and ways to study system complexity. Drs. Rainey and Jamshidi are to be congratulated both for their vision of the book and their success in recruiting contributors with so much to say. Most notable, however, is that this is a book with engineering at its core. It uses modeling and simulation as the language in which to express principles and insights in ways that include tight thinking and rigor despite dealing with notably untidy and often surprising phenomena." — Paul K. Davis, RAND and Frederick S. Pardee RAND Graduate School The first chapter is an introduction and overview to the text. The book provides 12 chapters that have a theoretical foundation for this subject. Includes 7 specific example chapters of how various modeling and simulation paradigms/techniques can be used to investigate emergence in an engineering context to facilitate understanding, detection, classification, prediction, control and visualization of emergent behavior. The final chapter offers lessons learned and the proposed way-ahead for this discipline.
