4.2.14 Integrating All Modules Into Population Model

The Powersim™ Studio model resulting from integration of all four modules and simulation for 25 years (as a test of the model’s stability) is shown at Figure 4-28.

Key variables of the model integrating all four modules are the same as those defined in Tables 4-4, 4-5, and 4-6 respectively, except that as a result of integrating (assembling) these modules POPULATION is now defined as shown in Table 4-10.

Variable	Definition	Comment
POPULATION	Initial Population	Population Flow = + dt (Birthing) + dt (Migrating-in) - dt* (Migrating-out)–dt* (Dying). This flow definition is generated automatically by Powersim™ Studio as a result of the flow connections made to the stock POPULATION (and in the sequence in which those connections are made).
