Figure 1

Simple stock flow and population ratio model closing the gap between workforce and projected population requirements. Note: The conventions of systems dynamics mapping are followed in this and subsequent figures. Interactions notated as indicate that as the source increases the destination also increases. The dotted lines notated as indicate that an increase at the source decreases the destination. For example, an increase in the population increases the projected requirements which increase the student intake. However, increased graduates will decrease the projected requirements for more personnel. Regulators to flows in and out of the system are indicated by .
