Abstract: To satisfy the modeling and simulation requirements of complex system, a modeling and simulation framework of Simulation Model Portability (SMP2) based on Service Oriented Architecture (SOA) was put forward. By integrating SOA thought, a SMP2 simulation architecture oriented to service was proposed. Simulation model service description was added to the above architecture’s meta-model, and related SMP2 component interfaces were redefined. The process of SMP2 modeling and simulation under SOA was discussed. Aiming at the network characteristics of SOA, a graph-based hybrid time synchronization strategy was presented. And methods for constructing model interaction graph, evaluating the concurrence algorithm of the model and determining hybrid time synchronization strategy were also put forward. Finally, a SOA-based modeling and simulation Environment for SMP2 was designed and implemented, and the application of navigation system’s service performance analysis simulation was given to demonstrate the validity and feasibility of the method.
