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.

Abstract: A system and display for providing guidance to elevator passengers generates call data and transmits the call data to the group control systems of one or more elevator banks. The group control systems process the call data to produce group call data and distribute the group call data to an elevator controller of the elevator bank. The guidance system also includes a display device which displays the group call data for one or more group control systems.

Abstract: An allocation method in an elevator group for allocating a landing call to one of several elevator cars comprised in the elevator group, said cars moving and stopping within the area of several different floors, by using a genetic allocation method. In the method, the elevator travel routes are encoded into alternative chromosomes; using genetic methods, alternative chromosomes are developed and the best one among these is selected; and the elevator group is controlled in accordance with the best chromosome.

Abstract: The invention relates to a passenger guidance system which comprises means for generating call data (8) and means for transmitting call data (8) to the group control systems (7) of one or more elevator banks, said group control systems processing the call data to produce group call data (8; 8b) and distributing the said group call data (8; 8b) to the elevator control means (3) of the elevator bank. The guidance system comprises a display device (1) which is used to display the group call data (8; 8b) for one or more group control systems.
