Information

This is the System Dynamics controlled restricted Rate 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 upstream level can control the flow by telling it that it is empty, and that the downstream level can control the flow by telling it that it is full. This is accomplished by two Boolean control signals from the upstream and downstream levels to the rate element.

The controlled rate element must be placed between two controlling levels.
