Genetic procedure for the allocation of calls for elevators comprised in an elevator group. In the procedure, a plurality of allocation options, i.e. chromosomes (33) are formed, each of which contains a call data item and an elevator data item for each landing call, and these data, i.e. genes together define an elevator to serve the landing call. A fitness function value (34) is determined for each chromosome (33) and one or more of the chromosomes (33) are modified and, based on the fitness function values, the best chromosome (33) is selected and the elevator group is controlled in accordance with this chromosome. According to the invention, the chromosomes (33) and the corresponding fitness function values (34) are collected in a file, i.e. a gene bank, and each chromosome (33) generated is compared with the chromosomes (33) in the gene bank, and a fitness function value (34) is only determined for a new chromosome (33).
