Currently, service-oriented model and simulation has become a main development direction for modeling and simulation. In order to separate the simulation service and state and effectively reuse simulation resources, this paper proposed a simulation task unit (STU) model method based on role and state mode, in which role could call the simulation service by simulation member and the state value of simulation service could be saved in the state of role. This paper also analyzed the relations among role, state and logic, and described the simulation member model and simulation task model in detail. Besides, an STU model tool was developed for effectively modeling for STU, and this tool was proved to be useful for saving simulation service state in service-oriented model and simulation.
