This extended model adds additional process: a process that comes online in a selected year. This new process has the effect of of constraining processing capacity (flow rates from Start to Finish). Use the AltActivationYear Slider to change the year at which the main alternative process flow comes online. Use the SubProcActYear Slider to select the time a new, efficient, sub-process technology becomes available, And, use the SubProcMultiplier Slider to adjust the efficiency gains this new tech. provides (the range allows increases in 10% intervals up to a doubling of the original rate).
These features in this simple model allow users to explore the system performance variation based on a range of alternative assumptions and scenarios.
