Abstract: The present invention relates to servicing a car to a hall call in a group management system which controls a plurality of elevators installed in a building. A group management control method for an elevator according to the present invention is capable of decreasing an average waiting time and a waiting generation probability by selecting more than two cars having high evaluation values after evaluating each car using a synthetic evaluation function, and allocating one car which is regarded as an optimum car for servicing by applying a genetic algorithm which is known to be highly efficient in a system with a large search space.

Abstract: An improved group management control method for an elevator capable of efficiently performing a group management control of an elevator based upon the building condition by deciding a corresponding car to be allocated in accordance with a predetermined hall call based upon a traffic flow and the fuzzy theory which are differ from the characteristics of each building, which includes the steps of a traffic flow collecting step for collecting information concerning a current traffic flow occurred at each hall call and car; a traffic flow study step for studying information collected at the traffic flow collecting step; a traffic flow anticipating step for anticipating a traffic flow after a predetermined time based upon the information studied at the traffic flow study step; a specific mode judgement step for judging a specific mode corresponding to the traffic flow anticipated at the traffic anticipating step; an allocation control strategy establishment step for establishing control strategy for allocating a p
