Robust, integrated arrival-departure-surface scheduling based on Bayesian networks

• PROCAST combines two complementary technologies for performing integrated arrival-departure-surface trajectory optimization under uncertainty • BBNs provide a fast-computation method for generating multiple possible future traffic scenarios • GA optimizer provides an effective method to optimize trajectories for each of the multiple future traffic scenarios • Preliminary assessment shows good promise, but more rigorous tests are needed • Next steps • Extend the analysis to cover JFK terminal airspace, and further to cover the entire New York metroplex • Assess PROCAST benefits with a wider set of traffic scenarios
