Abstract
An elevator system having a plurality of elevator cars and supervisory control for directing their movement in a building to efficiently serve the floors therein. The supervisory control divides the floors and service directions therefrom, called scan slots, into sets, with a set being those scan slots served by the same combination of cars. The scan slots are assigned to the elevator cars using a predetermined strategy, with the sets being taken in a predetermined order determined by the number of cars enabled to serve the sets. The strategy breaks out of the rigid set concept when assigning scan slots to cars based upon car calls, to effect a significant improvement in elevator service.
