Abstract
An elevator system for a building having a plurality of floors, including supervisory system control for controlling a plurality of elevator cars to answer calls for elevator service from the plurality of floors. The system control assigns unassigned service directions from the plurality of floors to each of the elevator cars, until meeting a predetermined dynamic limiting average. The assignments are made to one car at a time, proceeding to the next when a predetermined limiting average is met. The order in which the cars are selected for assignment is a dynamic order, responsive to the relative work loads of the cars. The assignments are made to each car, starting in a predetermined direction from each car's position, and are terminated a predetermined travel distance from the car, if not terminated sooner due to a limiting dynamic average. A predetermined minimum limiting dynamic average may be set, to control the rate at which idle cars become busy cars when traffic increases.
