Abstract: The importance of system agility in simulation has been widely realized and understood. However, the current architecture of coordination logic in aerial warfare simulation is central "single layered", while it has total control over coordination process, but solidifies the coordination logic in the simulation system too. A service-oriented integration for coordination logic in the air combat simulation(ACS)was proposed. Based on the principle of separation of concerns, the solution provides mechanisms for factoring out coordination logic in the ACS, and then distributes them to a series of flexible coordinator proxy which extends passive component model into self-coordinating service. A service is autonomous and is contractually defined in a description. According to the specific simulation task, coordination logics are dynamic bind by interconnecting related services at run time, therefore promoting system agility in ACS.
