Abstract

Ground Holding is a technique that has been successfully employed to combat disruptions at North American airports.  However, this alone is insufficient to cope with the problem.  We develop an adaptive optimization model that allows for other tactics, such as flight cancellations, airborne holding and diversions to be implemented.While the approach is generic, for a realistic illustration, our model incorporates features of Sydney airport in Australia, such as a night curfew from 11:00pm to 6:00am.  For an actual day when there was a significant capacity drop, we demonstrate that our model clearly outperforms the actions that were initiated by the air traffic controllers at Sydney.  Another issue is the non-linear nature of delay costing.  We report on developing heuristics for these problems and results on their computational testing.

Biography

Prabhu Manyem obtained his undergraduate and postgraduate degrees in Civil Engineering at the Indian Institute of Technology.  He completed his Ph.D. in Discrete Optimization with a minor in Computer Science at North Carolina State University, Raleigh, NC, USA in 1996.  After working in the American industry for three years, he moved to Australia where he was an academic for more than ten years, first at the University of South Australia, then at the University of Ballarat.During 2009-13, he taught Mathematics at Shanghai University (China).He is currently a Professor and a YaoHu scholar at the Nanchang Institute of Technology, Nanchang, China.  His interests are in Computational complexity, Approximation algorithms and Discrete optimization.
