Space Elevator

Idle: 👩‍🚀    Up: 🚀    Down: 🛸


Nearest Car (NC): Elevator calls are assigned to the elevator best placed to answer that call according to three criteria that are used to compute a figure of suitability (FS) for each elevator. (1) If an elevator is moving towards a call, and the call is in the same direction, FS = (N + 2) - d, where N is one less than the number of floors in the building, and d is the distance in floors between the elevator and the passenger call. (2) If the elevator is moving towards the call, but the call is in the opposite direction, FS = (N + 1) - d. (3) If the elevator is moving away from the point of call, FS = 1. The elevator with the highest FS for each call is sent to answer it. The search for the "nearest car" is performed continuously until each call is serviced.
