ABSTRACT OF THE DISCLOSURE With this group control the assignments of cars (4) to floor calls can be optimized in such a manner, that minimal waiting times (will) result and the elevating capacity is increased. A computing device (CPU) provided for each elevator calculates at every floor a sum proportional to the time losses of the waiting passengers from the distance between the floor and the car position indicated by a selector (R 3), the intermediate stops to be expected within the distance and the instantaneous car load. By means of call register- ing devices (9) in the form of 10-key keyboards it is possible to enter calls for destination floors, so that at the time of calcula- tion,(together) with the floor calls simultaneously the car calls are available. The calculated lost time sum, also called servicing costs, is stored in a cost memory (RAM 4) provided for each elevator. During a cost comparison cycle the servicing costs of all elevators are compared with each other by way of a cost comparison device (12) where in each case in an assignment memory (RAM 5) of the elevator with the lowest servicing costs an assignment instruction can be stored, which designates that floor, to which the respective car (4) is optimally assigned in time.
