Robustness is increasingly important in large-scale transportation networks
in general, and in the air transportation network in particular. Air
transportation is drastically affected by weather, forcing reductions in
operations at two major airports per day on average. Complexity of aircraft,
baggage handling, ground support and other systems frequently result in
unpredicted problems. Flight-centric measures of performance do not reflect
the true costs of delay.
The talk provides an overview of the problems airlines solve. Examples of
the variety of solutions to these problems are examined, and the drastic
effect that the chosen solutions exert on several aspects of robustness are
explored.
