PURPOSE:To improve the transportation efficiency by calculating a service reduction floor due to the destination concentration of users, determining the transportation efficiency when an elevator scheduled to pass this floor and next stop at the specific floor is reversed to stop at this floor, and changing allocation. CONSTITUTION:When a group management controller 4 judges that destinations of users are concentrated at the specific floor with a judging means 9 based on the detection of an operation state detecting means 8, a service reduction floor is calculated by a calculating means 10 based on the elevator response time. A calculating means 11 calculates an elevator scheduled to pass the service reduction floor and next stop at the specific floor, the transportation efficiency when its advance direction is reversed and it stops at the service reduction floor is determined by a calculating means 12, and a response elevator allotting means 13 changes allocation and commands to corresponding unit controllers 5a... based on the calculated result so that the calculated elevator responds to the hall call at the service reduction floor. The transportation efficiency of the elevator can be improved to the utmost. |
