Research on rules of aggregation and disaggregation for aircraft entity models in air force combat simulation

Aircraft entity is the most important operational entity in air force combat simulation. Aggregation and disaggregation of aircraft entity models is one of the key issues badly-needed to resolve in multi-resolution simulation system. Basing on brief discussion of the method of entity oriented analysis (EOA), the characteristics of aircraft entities in air force combat simulation and the relationships among them were analyzed herein. Finally, through expatiating on the issues about aggregation and disaggregation for aircraft entity models in detail, some rules of aggregation and disaggregation for such entitiespsila attributes as position, velocity, and state were provided.
