Abstract
A group supervisory control device for an elevator includes a hall call assignment portion assigning a specific car to a hall call registered; an operation prediction portion predicting which is the operation to the next hall registered, regenerative operation or power running operation, and the time for which the regenerating operation or the power running operation is performed when the specific car has stopped at a responding hall; and a door open time control portion comparing the time for which the regenerative operation or the power running operation of the specific car is performed with the remaining running time of any other car performing the power running operation or the regenerative operation already predicted, calculating overlap time for the operations simultaneously, and making door open time set for the specific car changed to determine the door open time that can obtain longer overlap time, whereby a door is closed.
