PET Roadmap for FMS: DIS/ALSP to HLA Transition
Previous generation M&S: several paradigms (e.g. DIS for real time, ALSP for logical time), focused use, poor reusability or interoperability
New DoD M&S Vision e.g. SBA calls for maximal interoperability of simulations
HLA offers the global interoperability framework in terms of a high level distributed object model and a set of object management services
