Sölvelinga and Clarkeb (2014) studied the runway system has been a delay in departure procedures. And congestion in the station area, a large part of the delay of the entire flight. The idea of the aircraft are available. Scheduled to be in the form of a probability distribution. With due consideration to the runway with two parallel runways. When the plane arrived to take another path runway on departure from the timetable set by the input distributions and uncertainties described a specific algorithm to generate a sequence of actions in the aircraft on the runway. In order to get around the problem by reducing the time in a short time with these improvements can to get high quality solutions using less time. Particularly for cases with 14 aircraft in 1 minute or less, the calculation results show that the period fell by 5-7% when using a random algorithm and commitments compared with the grading plane. The format of the original work.
