ABSTRACT:
A method and apparatus for the control of the dispatch of elevator cars from the main floor are implemented in a plurality of algorithms performed by a process computer. A first algorithm for an elevator group receives data representing the measured arriving and departing building filling passenger traffic from sensors. The first algorithm determines the traffic requirements and the actual departure load of the elevator group from this data and various constants, and determines the transport capacity of the elevator group. The transport capacity is assigned to second algorithms associated with the elevator cars and corresponding to the nominal load of each respective car. Based upon the assigned transport capacity and the round trip time of the respective elevator car, the second algorithm calculates the nominal departure load. Dependent on the nominal departure load and the actual departure load, the second algorithm calculates a corrected departure load with which the elevator car should be loaded.
