ABSTRACT:
A group management method and apparatus for elevators is disclosed. The apparatus includes a car-position predicting device for predicting a car position and a car direction which will have been taken by each car when a predetermined time has elapsed, a predicted-empty-car detecting device for predicting from the predicted car position and direction an empty car which will be available when the predetermined time has elapsed, and an assignment restricting device for restricting the assignment of the predicted empty car to a floor call. In the group management method, a waiting time derived from a registered floor call which is assigned to each car is evaluated, and a car to be assigned to the floor call is selected on the basis of the result of the evaluation.
