Research on capacity of closely spaced parallel runways based on different operation models

This paper locate a research on the operation mode to closely spaced parallel runways through assigning appropriate seperation to arrival aircrafts.By constructing closely spaced parallel runways capacity evaluation model and calculating,then comparing capacity to closely spaced parallel runways of one departure after one arrival,two arrivals,and combined with simmod simulation software,it comes out that the better operation model to closely parallel runways in poor conditions is theoretically the two departures after one arrival of one departure and one arrival mode during the departure-peak period and other period remain use one departure after one arrival.
