Abstract

An apparatus for elevator group control in which the elevator is operated at many floors and dispensed at each floor according to the calling from each floor, comprising: an operation detecting device to detect the operation condition of the elevator; a transportation-focusing decision device to decide the objective floor according to the result of the operation detecting device; a non-priority detecting device to decide the priority of the transportation focusing floor according to the following conditions: (1) the elevator filled with people directing to the predetermined floor and moved until the elevator reaches the priority calling floor; (2) the elevator passing through a predetermined floor filled with people waiting for the elevator; (3) the calling period of a floor longer than the predtermined calling period; (4) the non-response period of a floor longer than the predtermined non-response period; (5) the elevator directed to an unidirection of a predetermined floor in which the non-response period of the floor reaches the moximum period; (6) the people at a floor entering the elevator less than a predetermined member; and (7) the present cumulative ratio of entering the elevator less than the cumulative ratio of the statistics in the past; then deciding the non-priority service floor; an elevator-responding device responding to the non-priority floor in the reverse direction of a moving elevator so that another elevator responds to the calling of the non-priority floor and moves to the non-priority floor.
