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 operating costs and assigning the call to the car with the lowest cost during a comparison cycle. The operating cost includes car load values for the floors which are stored in a load table for the assigned car. Upon the assignment of a floor call, the load value for the call input floor is increased proportionally to the number of entered calls and the load values at the floors of destination are reduced proportionally to the number of calls for the respective floor of destination. These load values are used by a monitoring circuit to prevent the assignment of a call which would cause an overload condition.
