Abstract |
During instances of capacity-demand imbalances, efficient
planning and decision-making in air traffic flow management is
contingent upon the "goodness" of the models that estimate
airport capacity over time. Airport capacities are subject to
substantial uncertainty as they depend on stochastic weather
conditions. In this talk, I will present statistical models
that we developed using a "seasonal clustering" technique to
estimate airport arrival capacity distributions, which are
required inputs into a class of stochastic ground holding
models that determine the optimal amount of ground delay to
assign to incoming flights. A method for adjusting the amount
of assigned ground delay in a dynamically changing Ground Delay
Program (GDP) will be presented. Based on an algorithm that we
developed to compare total weighted delay (after adjusting
appropriately), it will be demonstrated that the statistical
models yield less total weighted delay than do current
operational procedures.

Special Note for CA visitors: U.S. Citizens with a valid DOE badge can report
to the Sandia badging office in building 911 to have their
badges activated for Sandia-California site access.
Be sure to tell the badge office to which building you will need
access.
E.g. for Building 921, you'll need access through the turnstile
facing the parking lot in front of Bldg 921.
