摘要： PROBLEM TO BE SOLVED: To accomplish hall call allotment control capable of enhancing group-management control performance such as shortening of an average waiting time in a traffic flow in a building variously varied. SOLUTION: In the group-management system for the elevator, an expected locus of the respective elevators is determined, an evaluation value of an expected interval relative to a target interval of the respective elevators after a predetermined time from the expected locus is calculated and hall call generated is allotted to the suitable elevator so as to make the expected interval come close to the target interval based on the evaluation value. At this time, the predetermined time for indicating the time to an evaluation time is made to an expected arrival time of the call of which the expected arrival time is longest or its neighborhood or one round time of each elevator. Accordingly, by the allotting control for making a car position relationship come close to the ideal state at the suitable evaluation time, control performance as the group-management system such as shortening of the average waiting time is enhanced.
