Traditionally, acquisition analyses require a hierarchical suite of simulation models to address engineering, engagement, mission and theater/campaign measures of performance, measures of effectiveness and measures of merit. Configuring and running this suite of simulations and transferring the appropriate data between each model are both time consuming and error prone. The ideal solution would be a single simulation with the requisite resolution and fidelity to perform all four levels of acquisition analysis. However, current computer hardware technologies cannot deliver the runtime performance necessary to support the resulting “extremely large” simulation. One viable alternative is to “integrate” the current hierarchical suite of simulation models using the DoD's High Level Architecture (HLA) in order to support multi-resolution modeling. An HLA integration -- called a federation -- eliminates the problem of “extremely large” models, provides a well-defined and manageable mixed resolution simulation and minimizes Verification, Validation, and Accreditation (VV&A) issues. This paper describes the process and results of integrating the Joint Modeling and Simulation System (JMASS) and the Joint Warfare System (JWARS) simulations -- two of the Department of Defense's (DoD) next-generation simulations -- using a HLA federation.
