<p>An elevator system is obtained which is capable of assigning a suitable car by taking into consideration a change of a maximum speed or an acceleration according to the result of prediction of a change of a car load or a moving distance with respect to a hall call. In the elevator system having a group management control device (20), provision is made for a destination floor registration unit (11) that registers a destination floor according to a call into a call registration device (10) at the time of call registration, and an assignment control unit (21) that assigns a suitable car to a destination call registration request from the call registration device (10). The assignment control unit (21) includes a prediction time calculation unit (22), and calculates a change of the moving distance of each car after the call assignment based on the destination floor, and at the same time calculates each floor arrival prediction time of each car using a speed or an acceleration thereof according to a calculated value of the change of the moving distance.</p> |
