Efficient capacity allocation in a collaborative air transportation system
This thesis proposes methods of allocating airport capacity to the users of the National Airspace System (NAS) during periods in which demand for the resources exceeds capacity. A metric by which the proposed methods are judged is the value that the users of the N AS are able to realize through the …

Evaluating passenger delays in the US domestic air transportation system
A fundamental component of any National Airspace System (NAS) performance evaluation is the cost impact of air traffic delays, and more generally capacity limitations, on the traveling passengers. In previous research it has been conclusively shown that flight delay data and flight centric metrics …

Modeling and Control of Networked Systems: Applications to Air Transportation
Growing air traffic has resulted in congestion and flight delays. Delays not only inconvenience passengers but also have negative environmental impacts and cause monetary losses for airlines. Reducing delays is therefore crucial for operating a sustainable, efficient, and robust aviation …

On Capacity Estimation and Capacity-Safety Relationship in an Air Transportation Network
Air transportation is a complex system of interlinked distributed networks in which different components have their own constraints and performance measures. For example, an airport network in which each airport is treated as a node and models the departures/arrivals of flights as links considers …

An analysis of the dynamics of the US commercial air transportation system
Major trends in the airline industry are analyzed to highlight key dynamics that govern the US domestic air transportation system. The hypothesis is that air travel supply and demand equilibriums, a reliance on outside capital, and intra-industry competition are among the most critical forces that …
