The research and comparison on the combination technology of models based on HLA simulation

In the HLA simulation system, there exist two kinds of model combination technology: the federation member level and the model level. In this paper, two kinds of model combination technology are introduced in detail, and through the comparison their advantages and disadvantages are analyzed. It shows that the combination on the member level is more applicable for the small simulation system, and the combination on the model level is more applicable for the medium and large simulation system.
