To achieve the parallel schedule of SMP2 models under the Service Oriented Architecture, a parallel schedule method of SMP2 model is put forward. The assignment method of serial model schedule task is promoted based on the analysis of the four traditional serial model schedule tasks in the SMP2.Then three schedule tasks which can not be scheduled parallelized were reformed and the schedule processes were introduced. Finally, the schedule service interface was extended and the parallel simulation component interface, time manager interface and message manager interface were defined to conduct the implementation of parallel simulation component.
