A B S T R A C T This group-control provides immediate allocation of floor- calls to elevator cars and better allocation decisions, and future overloads are more accurately determined. Misallocations are therefore avoided and the average waiting time for all passengers is reduced. For the purpose of determining the most favourable car, a computer in each elevator calculates, from the distance between a floor and the car-position indicated by a selector, from the intermediate stops to be expected within this distance, and the car-load, a total proportional to the time lost by waiting passengers. By means of call- recording devices, arranged at the floors, in the form of 10-button panels, calls for target-floors can be fed-in. After the calls have been stored, load-values contained in a load-table are altered in such a manner that they are increased at the input-floor in proportion to the number of calls fed-in, and are reduced at the target-floors in proportion to the number of calls for the relevant target- floor. The load-values thus determined are taken into account in calculating the total, a monitoring circuit preventing the allocation of calls which would cause overloads.
