ABSTRACT:
In an elevator system with the immediate allocation of the floor calls, car calls are processed according to an algorithm implemented in a process computer. A preliminary processing of the car calls occurs upon entry of each of the car calls and a final processing occurs before the car call destination floor. A car call with a destination floor which coincides with the destination floor of an allocated call is allocated immediately during the preliminary processing. If there is no coincidence, the car call is shortened by one floor and registered. A car call registered during the preliminary processing is allocated with its original trip length during the final processing if there is coincidence with a destination floor of an allocated call. If no coincidence exists, the car call is allocated with a new destination floor which depends upon the allocated calls before and/or after the original car call destination floor.
