Abstract
A method and apparatus for group-supervising an elevator system according to this invention consists in predicting the position of operating cages after the lapse of a predetermined time, detecting an unoccupied cage and tentatively setting the standby position thereof, so as to predict the position of unoccupied cages after the lapse of the predetermined time under the condition that the detected unoccupied cage is run to the set position and is caused to stand by there, predicting, from the positions of the cages, the number of cages which will lie in certain floors or certain floor zones after the lapse of the predetermined time and estimating the numbers of cages in association with the floors, whereby the floor in which the unoccupied cage is to stand by is selected.
