Technology for an individual soldier simulation interacting with a separate combat model simulation was demonstrated in 1995. This memorandum reports how Distributed Interactive Simulation (DIS) Protocol Data Units (PDUs) were used to integrate the soldier simulator and the computer-generated opposition forces into a seamless virtual environment.
Commissioned by the Society for Modeling and Simulation International (SCS), this needed, useful new ‘Body of Knowledge’ (BoK) collects and organizes the common understanding of a wide collection of professionals and professional associations. Modeling and simulation (M&S) is a ubiquitous discipline that lays the computational foundation for real and virtual experimentation, clearly stating boundaries—and interactions—of systems, data, and representations. The field is well known, too, for its training support via simulations and simulators. Indeed, with computers increasingly influencing the activities of today’s world, M&S is the third pillar of scientific understanding, taking its place along with theory building and empirical observation. This valuable new handbook provides intellectual support for all disciplines in analysis, design and optimization. It contributes increasingly to the growing number of computational disciplines, addressing the broad variety of contributing as well as supported disciplines and application domains. Further, each of its sections provide numerous references for further information. Highly comprehensive, the BoK represents many viewpoints and facets, captured under such topics as: Mathematical and Systems Theory Foundations Simulation Formalisms and Paradigms Synergies with Systems Engineering and Artificial Intelligence Multidisciplinary Challenges Ethics and Philosophy Historical Perspectives Examining theoretical as well as practical challenges, this unique volume addresses the many facets of M&S for scholars, students, and practitioners. As such, it affords readers from all science, engineering, and arts disciplines a comprehensive and concise representation of concepts, terms, and activities needed to explain the M&S discipline. Tuncer Ören is Professor Emeritus at the University of Ottawa. Bernard Zeigler is Professor Emeritus at the University of Arizona. Andreas Tolk is Chief Scientist at The MITRE Corporation. All three editors are long-time members and Fellows of the Society for Modeling and Simulation International. Under the leadership of three SCS Fellows, Dr. Ören, University of Ottawa, Dr. Zeigler, The University of Arizona, and Dr. Tolk, The MITRE Corporation, more than 50 international scholars from 15 countries provided insights and experience to compile this initial M&S Body of Knowledge.
The Distributed Interactive Simulation (DIS) system is an ambitious effort to take advantage of the tools of the information age to help improve the efficiency and effectiveness of the U.S. military services. It involves serious challenges in the areas of technology, interservice coordination, and verification, validation and accreditation (VV & A). The U.S. Army TRADOC Analysis Center (TRAC) has lead responsibility among the services for VV & A of the DIS system. As part of that responsibility, TRAC is sponsoring four efforts aimed at exploring the issues of VV & A of DIS. This report documents one of those four efforts commissioned by the TRAC Director, Mr. Michael Bauman, and is intended to take advantage of previous work done at RAND on exploratory modeling and on validation of models and simulations. The research was conducted in the Force Development and Technology Program of PAND's Arroyo Center, a federally funded research and development center sponsored by the United States Army. The intent of this work is to develop a framework that encompasses all of the potential uses of the DIS system and illuminates the validation or credibility requirements for each type of use. Because of the breadth of the potential uses of DIS, the resulting framework is general enough to address any military application of models and simulations. As such, it should be useful not only to the DIS community, but to developers, users, and consumers of models and simulations throughout the military services.
Report on distributed interactive simulation application which is able to place large numbers of syntactically and semantically correct distributed interactive simulation protocol data units on a network to simulate the traffic that would be generated by multiple distributed interactive simulation applications.
The Distributed Interactive Simulation (DIS) system is an ambitious effort to take advantage of the tools of the information age to help improve the efficiency and effectiveness of the U.S. military services. Defined broadly, the DIS system is an infrastructure for linking simulations, simulators and live military systems of various types from any of the U.S. military services at multiple locations to create realistic, complex, virtual 'worlds' for the simulation of highly interactive activities. It poses serious challenges in the areas of technology, interservice coordination, and verification, validation, and accreditation (VV&A). This report concentrates on the validation challenge and presents a framework that encompasses all of the potential uses of the DIS system. It then illuminates the validation or credibility requirements for each type of use. Because of the breadth of the potential uses of DIS, the resulting framework is general enough to address any military application of models and simulations.
Report on the evaluation of several protocol data unit (PDU) message structures porposed by the Special Task Group for Protocol Architecture (STGPA) and the synthesis of the best features of the leading candidates into a recommended prototype message structure for the next generation of distributed interactive simulation (DIS) PDUs.
Report defines a standard which establishes the requirements for entity information and entity interaction protocol data units (PDUs) exchanged between simulators participating in a distributed interactive simulation.
