PROBLEM TO BE SOLVED: To prevent slow running by taking precedence on car calling at the time of congestion by providing, in a group control device, a table for managing the car calling of each elevator and a hall calling state and determining the concentration of calling to a certain floor by the constant number of times or higher and by a constant ratio or higher of all. SOLUTION: A present running method is permitted when the content of a car calling management table 1-2 satisfies a condition registered in a permission condition table 1-3. When new car calling to a particular floor is made in this state, a new hall calling allotment to an elevator where car calling is made is masked and, at the same time, previously allotted hall is canceled. Then, until the elevator reaches the particular floor and its door is opened, express running execution is broadcast to the hall of each floor and its car. Also, the canceled hall calling is allotted to another elevator again. The end of the present running method permission is determined based on conditions including the number of car calling, a concentration ratio, and others and a finishing time. |
