Monitoring and Mitigation of Air Traffic Delays

Hamsa Balakrishnan
Massachusetts Institute of Technology

Abstract
Flight delays result in significant costs to passengers, airlines, and society as a whole. This fact motivates the development of models that can help characterize air traffic delays, and optimization algorithms that can help us reduce them.

In the first part of the talk, I will describe the development of a new class of networked system models of delay dynamics. These models reflect both the spatial properties (i.e., inter-airport interactions) and temporal patterns of delay propagation. They also provide features that can help assess various aspects of system resilience, and even predict the future evolution of delays.

In the second part of the talk, I will present an integer programming approach to mitigate flight delays by solving large-scale air traffic flow management problems in the presence of capacity uncertainties. The proposed stochastic optimization approach uses column generation to determine the optimal departure times, routes, and cancellation decisions for all flights in the air traffic network, allowing for recourse as the scenarios develop. Using nation-scale examples from the United States, I will demonstrate that the approach is scalable and fast enough for real-time implementation.

Biography
Hamsa Balakrishnan is an Associate Professor of Aeronautics and Astronautics at the Massachusetts Institute of Technology (MIT). Before joining MIT, she was at the NASA Ames Research Center. She received her M.S. and PhD degrees from Stanford University, and a B.Tech. from the Indian Institute of Technology Madras. Her research is in the design, analysis, and implementation of control and optimization algorithms for large-scale cyber-physical infrastructures, with an emphasis on air transportation systems. She is the co-founder and chief scientist of Resilient Ops, Inc.

Prof. Balakrishnan was a recipient of the NSF CAREER Award in 2008, the Kevin Corker Award for Best Paper of ATM-2011, the inaugural CNA Award for Operational Analysis in 2012, the AIAA Lawrence Sperry Award in 2012, and the American Automatic Control Council's Donald P. Eckman Award in 2014. She is an Associate Fellow of the American Institute of Aeronautics and Astronautics.
