SimWorx: An ADA Distributed Simulation Application Framework Supporting HLA and DIS

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, Easy_Sim. 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 \u27front end and a DIS \u27back end\u27 to provide DIS compatibility. The SimWorx framework was successfully integrated with Easy_Sim to provide an Ada based joint simulation system for distributed virtual simulations

Use of Federated Object Modeling to Develop a Macro-System Model for the U.S. Department of Energy's Hydrogen Program; Preprint

DOE is working on changing transportation fuel to hydrogen. To assist in that effort, we are developing a macro-system model that will link existing or developmental component models together
