Metamodel applications using TERSM

Tactical simulation models are often used to assess vulnerabilities and capabilities of combat systems and doctrines. Due to the complexity of tactical simulation models, it is often difficult to assess the relationship between input factors and the performance of the simulation model. To facilitate this type of assessment, simulation analysts often use the simulation model to empirically construct a black-box approximation of the causal and time dependent behavior of the simulation model. This type of approximation is known as a metamodel and can be viewed as a summary of the behavior of the simulation model. We demonstrate this technique in the context of an example using TERSM (Tactical Electronic Reconnaissance Simulation Model). The results indicate that metamodeling is applicable to tactical simulation models and that the technique has a wide range of uses
