blockCInflow

Controlled inflow element

Information

This is the System Dynamics controlled restricted Inflow element, whereby the rate itself is determined by a single variable in its laundry list. This element is a restricted rate element with the additional feature that the downstream level can control the flow by telling it that it is full. This is accomplished by a Boolean control signal from the downstream level to the rate element.

The controlled inflow element should e.g. be used to model the access to a parking garage. Additional cars are only admitted as long as the garage is not full.
