Abstract
An elevator system including supervisory system control for controlling a plurality of elevator cars to answer calls for elevator service. The supervisory system control, using information provided by the cars, groups the floors of a building, and service directions therefrom, into sets, each of which indicates those floors and service directions served by the same combination of in-service elevator cars. The supervisory system control periodically determines, for each set, the average number of floors and service directions therefrom, and the average number of calls, per in-service elevator car serving the set. The supervisory system control then assigns floors and service directions therefrom to the cars, using these averages, to substantially equally distribute the floors, and service directions therefrom, for each set, among the elevator cars serving the set, as well as to substantially equally distribute the calls for elevator service among the elevator cars.
