Abstract (en)
In an elevator system which enables a subset of a plurality of elevators under group supervisory control to be switched to exclusive operations, it becomes possible to prevent a decrease in the operation efficiency of the whole system and to perform switchovers to exclusive operations quickly. For this purpose, the elevator system is provided with a call registration device with which an elevator user registers his or her destination floor before getting in a car and an exclusive operation switchover device which sends a switchover request in order to switch a subset of the plurality of elevators to exclusive operations. Upon receipt of the switchover request from the exclusive operation switchover device, service time for destination calls which have already been registered by the call registration device is computed regarding the subset of the elevators. On the basis of the computed service time, services for some of the destination calls is performed in a range not exceeding a prescribed threshold value and switching the subset of the elevators to exclusive operations is performed without performing services for the remaining destination calls.
