  • Patent number: 9695009
    Abstract: An elevator system includes a group control device (12) and a destination call registration device (9). The group control device (12) performs group control of a plurality of elevator devices. Each of the elevator devices includes a plurality of cars which ascend and descend in the same shaft. The destination call registration device (9) is installed in an elevator hall. Moreover, the group control device (12) includes a first determination unit (15) and an assigned car determination unit (18). The first determination unit (15) tentatively assigns a call newly registered from the destination call registration device (9) to a first car, and excludes the first car from candidate cars of a first group in a case where a second car arranged above or below the first car stops at the hall before the first car. The assigned car determination unit (18) selects a car to which the new registration call is assigned from the candidate cars of the first group.
