A method for controlling an elevator group of double-deck elevators. Landing calls are allocated to the elevators and elevator decks in such a way that the passenger journey time is optimized. The method takes into account the current landing call time and the estimated time of arrival to the destination floor. The method minimizes passenger journey time by allocating the landing call to the deck that will cause the fewest additional stops to the elevator and least additional delay on the way to the passenger destination floor. In addition, the elevator estimated time of arrival to a destination floor is calculated separately for each deck, taking into account the stops already existing for the elevator and the additional stops caused by the selected landing call. Further the landing call is allocated to the deck for which the estimated time of arrival to the destination floor is least. In addition, the best deck for each landing call is selected by minimizing a cost function. The cost function may include the estimated time of arrival to the destination floor. Alternatively, the cost function may also include the estimated time of arrival to the furthest call floor.
In a system of plural elevators arranged in an elevator group and being driven by a drive system allowing coordinated control of each elevator of said elevator group by an elevator control, the individual elevators having multiple decks accessing plural adjacent floors, each elevator including at least an upper deck and a lower deck, a method of controlling the elevator group comprising:
