Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.

Download or read book Parallel and Distributed Simulation Systems written by Richard M. Fujimoto and published by Wiley-Interscience. This book was released on 2000-01-03 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: A state-of-the-art guide for the implementation of distributed simulation technology. The rapid expansion of the Internet and commodity parallel computers has made parallel and distributed simulation (PADS) a hot technology indeed. Applications abound not only in the analysis of complex systems such as transportation or the next-generation Internet, but also in computer-generated virtual worlds for military and professional training, interactive computer games, and the entertainment industry. In this book, PADS expert Richard M. Fujimoto provides software developers with cutting-edge techniques for speeding up the execution of simulations across multiple processors and dealing with data distribution over wide area networks ,including the Internet. With an emphasis on parallel and distributed discrete event simulation technologies, Dr. Fujimoto compiles and consolidates research results in the field spanning the last twenty years, discussing the use of parallel and distributed computers in both the modeling and analysis of system behavior and the creation of distributed virtual environments. While other books on PADS concentrate on applications, Parallel and Distributed Simulation Systems clearly shows how to implement the technology. It explains in detail the synchronization algorithms needed to properly realize the simulations, including an in-depth discussion of time warp and advanced optimistic techniques. Finally, the book is richly supplemented with references, tables and illustrations, and examples of contemporary systems such as the Department of Defense's High Level Architecture (HLA), which has become the standard architecture for defense programs in the United States.
Download or read book NPSNET Integration of Distributed Interactive Simulation DIS Protocol for Communication Architecture and Information Interchange written by and published by . This book was released on 1993 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Computer Science Department at the Naval Postgraduate School in Monterey, California has developed a low-cost real-time interactive network based simulation system, known as NPSNET, that uses Silicon Graphics workstations. NPSNET has used non-standard protocols which constrains its participation in distributed simulation. DIS specifies standard protocols and is emerging as the international standard for distributed simulation. This research focused on the development of a robust, high-performance implementation of the DIS Version 2.0.3 protocol to support graphic simulation systems (e.g. NPSNET). The challenge was to comply with the standard and minimize network latency thereby maintaining the time and space coherence of distributed simulations. The resulting DIS Network Library consists of an application program interface (API) to low level network routines, a host of network utilities, and a network harness that takes advantage of multiprocessor workstations. The library was successfully tested on our local network and two configurations of a T-I based internet, the Defense Simulation Internet (DSI), with the Air Force Institute of Technology and Advanced Research Projects Agency. The testing confirmed that the semantics and syntax of the DIS protocol is properly implemented and the latency incurred by the network does not adversely effect the simulation application.
Download or read book SimWorx written by Earl Conrad Pilloud and published by . This book was released on 1996-12-01 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research consisted of the analysis, design, and implementation of a reusable application framework for distributed simulation which is compliant with both the DoD High Level Architecture (HLA) for Modeling and Simulation and the Distributed Interactive Simulation (DIS) standards. The goal was to create an Ada-based system for experimentation in distributed simulation. A subsidiary goal was to integrate the system with an existing Air Force Institute of Technology (AFIT) application framework for virtual simulations, EasyÆSim. The application framework was designed using object oriented techniques to enable experimenters to customize it via inheritance extension. The application framework, named SimWorx, consists of two sections: an HLA federate skeleton, and a surrogate HLA Run Time Infrastructure (RTI) which has an HLA 'front end" and a DIS 'back end' to provide DIS compatibility. The SimWorx framework was successfully integrated with EasyÆSim to provide an Ada based joint simulation system for distributed virtual simulations.

Download or read book Applied System Simulation written by Mohammad S. Obaidat and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simulation and molding are efficient techniques that can aid the city and regional planners and engineers in optimizing the operation of urban systems such as traffic light control, highway toll automation, consensus building, public safety, and environmental protection. When modeling transportation systems such as freeway systems, arterial or downtown grid systems, the city planner and engineer is concerned with capturing the varied interactions between drivers, automobiles, and the infrastructure. Modeling and simulation are used to effectively optimize the design and operation of all of these urban systems. It is possible that in an urban simulation community workshop, citizens can work interactively in front of computers and be able using the click of the mouse to walk up to their own front porch, looking at the proposed shopping mall alternatives across the street from virtually any angle and proposed bridge or tunnel and see how it can reduce traffic congestion. Buildings can be scaled down or taken out, their orientation can be changed in order to check the view and orientation in order to have better site with efficient energy-conservation. The stone or brick material on a building can be replaced by colored concrete, or more trees and lampposts can be placed on the site. Such flexibility in simulation and animation allows creative ideas in the design and orientation of urban sites to be demonstrated to citizens and decision makers before final realization.
