Training simulation is broadly used in military training but not limited. The simulation environment contains so many elements and so many factors affect the result, so an effective and efficient mechanism to help to manage these factors is required. This article firstly listes the elements in the environment, and then builds the object models of all kinds of objects. Based on these object models, the experiment frame is designed. Finally, a simple case study is given. According to the actual application, these models and frame facilitate the experiment management and help the analysts to analyze the simulation result.
