Abstract

A group-supervisory apparatus for an elevator system includes an apparatus which registers hall calls when hall buttons are depressed, selects a cage to serve from among a plurality of cages and assigns it to the hall call, performs 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 causes the cage 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 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. Also, it 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. At least one of the functions of selecting a cage, performing operation controls, and causing the cage to stand by is performed using the predicted number of the cages.
