In a group of elevators with double cars, the assignment of such double cars to floor calls takes place at scanner positions ~ in two procedural steps, according to two parameters: primarily by assignment of the individual cars of all double cars by logical decision, according to a criteria chain (KK), and subsidiarily by assignment of the double cars according to the minimal loss time of all involved passengers. The individual elevators each have a microcomputer system with a calculating device and are connected with each other by way of a comparator circuit to form a group control. The optimal individual cars are assigned for each elevator by floor in the associated individual car/call assignment memories. The optimal double car is selected by comparison of the loss times of all elevators calculated as the total operating costs K g (~) and is assigned to the respective floor in the associated double car/call assignment memory. For the total servicing costs K g(~), a special cost calculating algorithm is provided. With the separate assignment of individual cars and double cars, this group control renders possible a complete utilization of the double car functions as well as a good matching to different operating and traffic conditions. At the same time, the minimal waiting time of the passengers is optimized.
