An extended HLA multilayer federation integration architecture for multidisciplinary collaborative simulation

The development of complex products is essentially concerned with multidisciplinary knowledge. Running on Internet, integration based on multilayer federation architecture and dynamic reuse of simulation resources are the major difficultiesfor complex product collaborative design and simulation. Since the traditional Run-Time Infrastructure (RTI) is not good at supporting these new requirements, an extended high level architecture (HLA) multilayer federation integration architecture (MLFIA), based on the resource management federation (RMF) and its supporting environment based Service-oriented architecture (SOA) and HLA (SOHLA) are proposed, The idea and realization of two key technologies, the dynamic creation of simulation federation based on RMF, TH_RTI, an extensible HLA runtime infrastructure (RTI), used at Internet are emphasized. Finally, an industry case about multiple unit (MU) is given.
