Floor numbering Further information: Floor numbering The elevator algorithm residential lift The elevator algorithm, a simple algorithm by which a single elevator can decide where to stop, is summarized as follows: Continue traveling in the same residential lift direction while there are remaining requests in that same direction. If there are no further requests in that direction, then stop and become idle, or change direction if there are requests in the opposite direction. The elevator algorithm has found an application in computer operating systems as an algorithm for scheduling hard disk requests. Modern elevators use more complex heuristic algorithms to decide which request to service next.
