A doctrine-oriented MRM method in HLA-based simulation

MRM (Multi-resolution modeling) is becoming more important as large complex distributed simulations are carried out inside and out of military simulation community. Most current distributed simulations are implemented in the framework of HLA (High level architecture), which was originally defined by US DOD (Department of defense) and has been accepted by IEEE and OMG as an industrial simulation standard. This paper analyzes the requirements of MRM in HLA (High level architecture)-based simulations. Traditional most adopted practical method "aggregation/disaggregation" has temporal inconsistency problem because it discard the other level as it's at one level. The mainstream theoretic method "MRE (Multiple representation entity)" conquers this problem by propagating changes at one resolution to others, but it has weakness in mapping consistence. This paper suggested a doctrine-oriented MRM method. This novel method has good operational easiness and keeps the consistency problem simpler than MRE by enforcing unidirectional map between entities in different resolutions. A case study is also provided to illustrate its advantage to aggregation/disaggregation method.
