PURPOSE:To effect uniform service for a plurality of main floors according to the change of a crowding time zone by providing a cage allotting means to effect allotment of cage to a plurality of the main floors according to a traffic ratio. CONSTITUTION:When a first floor platform up calling signal 1U and B floor platform up calling signal BU are simultaneously inputted to an allotment computing device 1, a riding-on load ratio X between the two main floors of a first floor and B floor during past five minutes is determined. An allotment ratio Y when allotment to first floor is effected is determined. Consecutively, an allotment ratio Z when allotment to a H floor is effected is determined. An absolute value M (=¦X-Y¦) of a difference between the riding-on load ration X and and allotment ratio Y is then determined to determine an absolute value N (=¦X-Z¦) of a difference between the riding-on load ratio X and the allotment ratio Z. The magnitude of the absolute valve M and that of the absolute value N are compared with each other, and when M is lower than N, a cage is allotted to first floor platform up calling. When M exceeds N, a cage is allotted to B floor platform up calling. By repetition of a series of the routines, the cage of an elevator is properly allotted to a first floor and H floor. |
