Abstract
A group control for an elevator system, in which it is possible to assign a newly entered floor call to a car for the first time, immediately and finally, includes a computer and a comparator circuit for calculating servicing costs and assigning the call to the car with the lowest cost during a comparison cycle. The floor call generates an entry floor signal which is stored in a floor call memory and an assignment memory for the assigned car. Storage cells of the assignment memory and the floor call memory are linked to each other by way of an automatic holding circuit that prevents reassignment of the floor call during subsequent comparison cycles.
