Abstract

An elevator system having a plurality of elevator cars mounted in a building to serve the floors therein. Supervisory system control periodically assigns service directions from the floors to the elevator cars by dividing the service directions among the elevator cars within the constraint of at least one predetermined dynamic limiting average responsive to a predetermined parameter of the elevator system. A predetermined travel distance limitation may also be applied to at least certain of the elevator cars. A traffic level detector indicates when the traffic demand in a predetermined service direction reaches a predetermined level. When the traffic level detector indicates the traffic in the predetermined direction is at this level, the effect of the constraint, or constraints, is modified to allow more elevator cars to receive service direction assignments in the predetermined service direction.
