Abstract: The boost in the handling capacity of destination elevator group control systems has been previously calculated under idealised conditions, assuming simultaneously minimum values of the highest reversal floor and of the average number of stops in a round trip. The boost has also been calculated under conditions of allocating the landing calls with full advanced knowledge of the passenger destinations (offline allocation). This paper re-calculates the boost in handling capacity under real time allocation conditions of the landing calls as they are registered. The landing calls are revealed to the controller one at a time, and the controller has to make an irrevocable allocation of the landing call to an elevator. The efficiency drops under real time allocation conditions compared to the other two conditions as expected. However, it still reveals a significant boost in handling capacity that increases with the number of elevators in the group.
