Figure 6.

Model verification and substantiation iterations and activities conducted. The activities carried out as part of the model verification and substantiation process, which we briefly outlined in Figure 5, can be further broken down to a more detailed view. The diagram represents this iterative process in a linear fashion, where three iterations have been conducted. The model substantiation activity performed at the end of each iteration is marked with I, II, and III, which corresponds to the results summary shown in Figure 7.
