Abstract
A genetic allocation method in an elevator group for allocating a landing call to one of several elevator cars in the elevator group, the cars moving and stopping within the area of several different floors. The elevator travel routes are encoded into alternative chromosomes. Using genetic methods, alternative chromosomes are developed and the best chromosome is selected. The elevator group is controlled in accordance with the best chromosome. The floors served by the elevator group are divided into a first group and a second group. On the floors of the first group, landing calls are given as passenger-specific destination calls. On the floors of the second group, landing calls are given as floor-specific up/down calls. When the destination calls and up/down calls are encoded into the same chromosome, the best chromosome represents an allocation decision, in which the gene values indicate which elevator car is to serve each passenger and each up/down call.
