PURPOSE:To reduce the riding time and to make the one round times of plural elevators even by using a simple control device with no learning function, by providing a first limit value and the second limit value as to stopping number in one direction of the plural elevators. CONSTITUTION:The frequency of stopping each elevator for hall calls and car calls is calculated (201). Then, check is made for an elevator whose frequency of stopping does not reach a first specific value or not (202), and when there is such an elevator, the waiting time of the elevator is calculated (203). And the allocated elevator whose waiting time is the minimum is determined (204). When there is no elevator whose stopping number is less than the first specific value, at 202, the elevator whose stopping number is less than the second specific value is checked (207). And the waiting time of the elevator whose stopping number is less than the second specific value is calculated (209). The allocated elevator whose waiting time is made the minimum is determined (210). The waiting time can be reduced consequently. |
