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 passen…
