Group Supervisory Control
A control layer that coordinates two or more elevators serving a shared group of floors.
With conventional hall-call service, the system coordinates which car answers each landing request. With destination-oriented service, a passenger enters a floor before boarding and the system directs them to a car, reducing the number of stops per trip.
Each car still has its own controller. Group supervisory control coordinates service across the bank; dispatching is the process of assigning calls and cars.
