SimWorx: An ADA Distributed Simulation Application Framework Supporting HLA andDIS

摘要

This research consisted of the analysis, design, and implementation of a reusableapplication 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 'front end and a DIS 'back end' 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.
