HLA-BASED SIMULATION ARCHITECTURE AND SCHEDULING

HLA lays down a foundation for modeling and simulation. Based on recent HLA/RTI documents, this paper proposes a "distributed-centralized" HLA simulation architecture. Then it describes a method of analyzing the hierarchical scheduling problem and its time Petri net model for performance analysis. The method compromises with as-fast-as-possible analysis federates and independent time advance real-time federates on time service demand, and it solves the real-time cooperative problem among continuous simulation applications. What's more, the scheme is easy ,controllable ,and expansible.
