Description: As the Department of Defense (DoD) continually relies more on Modeling and Simulation (M&S) for testing, analyzing, and training, issues of interoperability have become one of the most important concerns. As such, DoD adopted the Distributed Interactive Simulation (DIS) protocol in 1991. Although successful in many      aspects, DIS is limited by available information from models, memory and network requirements, and      analytical tools available. Therefore, in 1996 the Defense Modeling and Simulation Office (DMSO) released the High Level Architecture (HLA), an object oriented approach to interoperability. This thesis compares these different approaches to analysis to determine functionality in terms of gathering, processing, and      reporting on analytical questions in both environments. To compare DIS and HLA analysis, three simulation runs were conducted: Janus vs. Janus in DIS, HLA without an Analysis Federate, and HLA with an Analysis Federate. The Analysis Federate is an HLA compliant software package that gathers and processes information for analysis requirements. The results of the three simulation runs and subsequent analysis      demonstrated the techniques and approaches for each infrastructure. The resulting comparison between them show HLA with the Analysis Federate is the easiest and most functional tool. The Analysis Federate fills an      analysis void currently in HLA and by implementing it with the study question model tree methodology, an analyst will be more effective and be able to provide real time feedback.
