Mapping from BOM conceptual model definition to PDES models for enhancing interoperability

Parallel discrete event simulation (PDES) and high level architecture (HLA) based distributed simulation need to collaborate to conquer the large-scale complex systems. PDES aims at making best use of supercomputing resources while HLA focus on the interoperability of geographically distributed independent simulations. This presents particular challenges on the interoperability between PDES and HLA based simulation. This paper proposes a model mapping framework for mapping the Base Object Model (BOM) conceptual model definition into parallel discrete event simulation models, providing the common semantic basis with federation object models (FOMs) that transformed from the same BOM. With the guide of this framework, the entity types, event types, pattern of interplay and state machines could be mapped into PDES simulation objects, events, event scheduling relationship, and state transition, respectively. A case study about social simulation indicates that this approach not only makes the development of PDES models easy, but also facilitates the conceptual interoperability between PDES and HLA based distributed simulations.
