Applicability of Open Standards
|
Article by: Andreas Tolk
The paper "Composable Mission Spaces and M&S Repositories - Applicability of Open Standards" on top of the recommended reading list of the recent Spring Simulation Interoperability Workshop 2004 (04S-SIW-009) deals with challenge of generating a federation "on the fly." So far, no satisfying solution serving this need has been accomplished. The use of open source doesn't satisfy the industry, which has a vital interest to keep their core solutions in-house and to protect their intellectual property. The use of interface-driven solutions based on black boxes leads to discrepancies and inconsistent federations, as has been shown in the paper on top of the recent Fall Simulation Interoperability Workshop 2003 (03F-SIW-007), in which the Levels of Conceptual Interoperability Model (LCIM) was introduced....

Comments from the Departing U.S. Army Model and Simulation Office Director
|
Article by: Dell Lunceford
It’s amazing how little we know after all these years.….Myst
In the 8 March 1999 issue of Simulation Technology Magazine I wrote a short article that started out “One of the nice things about making a job change is that it gives you the opportunity to reflect on what you have been doing and where you are headed”. At that time I was leaving DARPA where I had been the PM for Advanced Simulation Technology and was moving to the U.S. Army Model and Simulation Office (AMSO), initially as the Technical Director and soon thereafter promoted to the ranks of the Senior Executive Service (SES) and made the Director. I now find myself in the position once again of moving on, retiring from civil service after 30 great years, so the opportunity comes once again to sit back and reflect on where the M&S community is and how far it has come in the intervening 5 years since I wrote the 8 March article....

Experiences Using the Six Services of the IEEE 1516.1 Specification: A 1516 Tutorial
|
Article by: Robert Lutz and Sean Murphy
The National Space Biomedical Research Institute (NSBRI) has sponsored a research program over the past three years intended to demonstrate the ability to simulate integrated human function over time. The specific goal was to verify that interoperable simulations of human physiological functions applicable to the spaceflight environment, executing interactively, can produce integrated results that cannot be produced by these same simulations executing independently....

ABSTRACT:
This paper addresses the issue of supporting large-scale agent-oriented simulation systems using end-host multicast. End-host multicasting is required when IP multicasting is not available, as in the case of much of the current Internet. Using a previously developed agent architecture for distributed simulation, we present a suite of highly-adaptive agent interconnection algorithms using overlay multicasting techniques. We have experimentally evaluated our approach under a number of different scenarios. Analysis shows that it is possible to achieve end-to-end system performance comparable to native network-layer multicast for agent-based systems using end-host multicast....

1 Introduction
Characteristically the approach for defining a model representation for a federation, which is often referred to as a Federation Object Model (FOM) in HLA, is to focus on matching system capabilities of federates that come closest to supporting the perceived needs (i.e. the requirements) of the federation, or choosing an existing and well-adopted FOM whether or not it maps and fully supports the perceived needs of the federation.
However, a more effective and efficient way for creating a model representation for a federation and facilitating reuse begins with the identification of the conceptual models....

Enabling Space M&S in Army Models
|
Article by: Alesya Paschal, Kevin Crumlish, Matthew Gorevin
Background
The Army Space M&S Focus Area Collaborative Team (FACT) was formed to address the deficiency of space representation in Army M&S. The Space FACT, led by SMDC, is an Army-wide multi-disciplinary team comprised of community experts to research, identify, and coordinate simulation technology projects in space M&S. The FACT developed a roadmap for space representation in Army M&S. The initial enabling technology identified is to develop a generalized representation of satellites. The Generalized Representation of Space-based Platforms (GRoSP) algorithm was developed to fill this capability gap. The objective of the GRoSP project was to develop a fast running representation of individual space-based systems that could quickly provide satellite locations to real time simulations....

Environmental Data Models: Necessary but Not Sufficient for Interoperability
|
Article by: Virginia T. Dobey, Peter L. Eirich

Peter L. Eirich
Keywords: interoperability, physical environment, natural environment, environmental representation, EDM, environmental data model, data model, normalization
ABSTRACT: During the past several years, the concept of an “Environmental Data Model” (EDM) has arisen within the simulation community for the development of environmental representations. An EDM, in the form of a logical data model, describes the environmental data elements found in either a specific environmental data source or in an application. This paper cites studies and experiments revealing that EDMs, in the way they are presently constituted, and even when supplemented by tools such as equivalence classes and environmental ontologies, were not adequate to permit computer-based analyses to fully discover the potential extent of application interoperability that could be expected. ...

Evolution of the Standard Simulation Architecture
|
Article by: Jeffrey S. Steinman, Douglas R. Hardy
Abstract
This article proposes the standardization of a layered simulation architecture that addresses many of the critical modeling needs of the DoD simulation community. The Standard Simulation Architecture works with HLA to provide the additional infrastructure that is necessary for developing highly interacting yet decoupled software models, while simultaneously supporting technology infusion from R&D organizations. The overall goal is to provide a cost-effective solution that features complete flexibility for simulation systems without sacrificing performance....

Linking Live, Virtual, and Constructive Environments for Digital Battle Command Testing and Training
|
Article by: Mary Anne Tatum
Introduction
Situational awareness (SA) and digital battle command and control (C2) are crucial to the continuing success of the U.S. Army. Operation Iraqi Freedom (OIF) clearly demonstrates that success on the battlefield is due not only to the skillful use of advanced weapon systems, but also to the effective use of digital battle command systems. The war has also highlighted the importance of using realistic synthetic environments for operational testing and training....

Welcome to the Fall 2004 edition of the SISO Simulation Technology On-Line Magazine. The M&S community and profession is ever growing and the challenges we face can sometimes seem daunting. But however difficult, these challenges are interesting and most often fun to take on and solve. In the process we grow as a community and present real solutions to real issues and leave a lasting and positive impact on our community and those we serve. SISO plays a critical role in supporting this ever growing community of M&S professionals in addressing these challenges by advancing new ideas in the form of technologies, standards and best practices all aimed at improving the application of M&S solutions and meeting the community’s needs. We believe that this on-line magazine supports and enhances that role and we are proud of the contribution it makes. ...
