In one example, the controller dispatches an elevator car to the requested destination on a next trip of that car if the expected arrival time of the passenger near that car occurs at or before the departure time for that next trip. Otherwise, the controller dispatches the car to the requested destination on a subsequent trip after the next trip. | 03-10-2011 |
