ABSTRACT:
A group supervision apparatus for an elevator system having hall call registration devices for registering each hall when a hall button is depressed, assignment apparatus for selecting a cage to-serve from among a plurality of cages and assigning the selected cage to the hall call, cage control apparatus for performing operation controls such as determining travelling directions of the cages, starting and stopping the cages, and opening and closing doors of the cages, and for causing the cages to respond to cage calls and the hall calls allotted to the assigned cages, and standby devices for causing, when the cages have responded to all the calls, the cages to stand by at floors where they have responded, or to run to predetermined floors and stand by; the apparatus being so constructed that cage positions and cage directions of the respective cages to arise after the cage calls and the allotted hall calls have been successively responded to since the present point of time, during a predetermined time, are predictively calculated by cage position prediction devices, that temporal intervals or spatial intervals of the respective cages to arise after the lapse of the predetermined time are predictively calculated on the basis of the predicted cage positions and the predicted cage directions by cage interval prediction devices, and that at least one of the assignment apparatus, the cage control apparatus and the standby devices is operated using the predicted cage intervals.
