ABSTRACT:
The group supervisory apparatus for an elevator according to one aspect of the present invention for assigning a plurality of cages to a hall of congestion when the congestion of the hall is detected comprises reference service interval setting means for setting a reference value of a period (hereinbelow termed "a reference service interval") from when the cage to be previously serviced becomes a first state states of a cage are termed arbitrarily upon operations, such as the decisions of the stop of the cage, the opening/closing operation of the door, the open state of the door, the start, or the stop) to when the cage to be serviced later becomes a second state of one of the above-described states in response to the traffic volume of the hall of congestion. This aspect of the present invention further comprises reference time setting means for setting a reference value of a time (hereinbelow termed "a reference time") when the other cage becomes the second state in the hall of congestion on the basis of the first state time of the predetermined cage and the reference service interval in response to the number of the cages of additional assignment, second state time predicting means for predicting a time when the cage becomes the second state in the hall of congestion, and additional assigning means for selecting and assigning the cage having a small deviation between the second state predicting time and the reference time as the cage of additional assignment.
