ABSTRACT:
An elevator allocation system includes an individual identifying device provided in each elevator hall and adapted to identify individual passengers. A measurement device for measuring each individual's waiting time between the moment a hall call is registered and the moment a car reaches the relevant elevator hall on the basis of the output of the individual identifying device is provided. A first memory device is provided to store waiting times measured by the measurement device. A first computation device then obtains each individual's average waiting time on the basis of the output of the first memory device. A second memory device stores average waiting times obtained on an individual basis by the first computation device. A second computation device computes an average of the waiting times of all passengers on the basis of the output of the first memory device and a third memory device stores the average of the waiting times of all passengers obtained by the second computation device. A preferential service preferentially allocates a car to a hall call registered by any passenger who has had an individual average waiting time longer than the average waiting time of all passengers on the basis of the outputs of the second and third memory device.
