PURPOSE:To equalize the travel interval of each elevator by setting the starting interval of elevators starting from a reference floor on the basis of the predicted arrival time computed by a predicted arrival time computing means and the judged result of no stand-by elevator judging means so as to reduce such a state as to have no stand-by elevator on the reference floor. CONSTITUTION:In a predicted arrival time arithmetic processing part S31 for a reference floor return specified elevator, the predicted arrival time to return to a reference floor is computed with the elevator, staying on the other floor and specified to return to the reference floor, as an object. A minimum predicted arrival time (tmin) selecting part S32 then selects the minimum reference floor return predicted time from the computed result of the predicted arrival time arithmetic processing part S31. In an average interval computing part S33, the minimum predicted time (tmin) is divided by the number of elevators standing by on the reference floor to compute the starting interval time t0 for equalization. |
