A group-supervisory apparatus for an elevator system according to this invention consists in an apparatus having hall call registration means for registering hall calls when hall buttons are depressed, assignment means for selecting a cage to serve from among a plurality of cages and assigning it to the hall call, cage control means for performing operation controls such as determining a traveling direction of the cage, starting and stopping the cage, and opening and closing a door of the cage, thereby causing the cage to respond to a cage call and the allotted hall call, and standby means for causing the cage when it has responded to all the calls, to stand by at a floor at which it has responded to the last call or to travel to and stand by at a predetermined floor; the apparatus being so constructed that cage position prediction means predictively calculates cage positions and cage directions after the respective cages have successively responded to the cage calls and the allotted hall calls since the current time and a predetermined time has lapsed, that cage number prediction means predictively calculates the presence or absence or the number of the cages which will lie at predetermined floors or in predetermined floor zones after the lapse of the predetermined time, on the basis of the predicted cage positions and the predicted cage directions, and that at least one of the assignment means, the cage control means and the standby means is operated using the predicted number of the cages. |
