The user might be interested in examining the model in depth to determine structure and understand behavior patterns. Provide the user unlimited access to the model through a set of Model Analysis screens. These can be accessed from the Main Menu. Once a simulation (or game) has been run, all the dataset analysis tools can be accessed for analyzing and tracking down model behavior. The structure of a model can be examined at any time with the structural analysis tools. These screens could be accessed from the Main Menu screen, or from within the Simulation Output screens, or from the Game Control. If multiple paths lead to a screen, multiple return paths must be included.
