The high level architecture: Is there a better way?

This paper first discusses the basic design approach adopted for the High Level Architecture and the design goals that it addresses in the military simulation arena. Next, the limitations of this architecture are discussed with particular focus on the real-time information requirements needed to support its operation. Finally, the paper discusses HLA´s inability to model complex systems with hierarchical command and control structures and the inherent limitations that this deficiency will impose upon the application of futuristic simulation technologies to military applications
