摘要：A zoned demand elevator system in which elevator cars are associated with the zone in which they become available for assignment. Each zone has a plurality of graded assignment levels, with an available car entering the highest vacant assignment level of the associated zone. Available cars in predetermined eligible assignment levels of all of the zones are considered when an available car is to be assigned to a demand for elevator rvice. The order in which the various eligible assignment levels of the zones are considered is determined by the nature of the demand. When an available car is assigned to a demand, available cars, if any, in lower graded assignment levels of that zone advance one assignment level, and an undesignated available car waiting for a graded assignment level to be vacated is given a graded assignment level designation.
