Analysis and Modeling of Ground Operations at Hub Airports
نویسندگان
چکیده
Building simple and accurate models of hub airports can considerably help one understand airport dynamics, and may provide quantitative estimates of operational airport improvements. In this paper, three models are proposed to capture the dynamics of busy hub airport operations. Two simple queuing models are introduced to capture the taxi-out and taxi-in processes. An integer programming model aimed at representing airline decision-making attempts to capture the dynamics of the aircraft turnaround process. These models can be applied for predictive purposes. They may also be used to evaluate control strategies for improving overall airport efficiency.

A combined statistical approach and ground movement model for improving taxi time estimations at airports
With the expected continued increases in air transportation, the mitigation of the consequent delays and environmental effects is becoming more and more important, requiring increasingly sophisticated approaches for airside airport operations. Improved on-stand time predictions (for improved resource allocation at the stands) and take-off time predictions (for improved airport-airspace coordina...
متن کاملApplication of Fuzzy Critical Path Method to Airport’s Cargo Ground Operation Systems
To cut down cost in a competitive environment, airlines must avoid delays and operation inefficiencies in both airside and landside. However, previous studies have paid little attention to an airlines’ ground operation in airports’ cargo terminals. The purpose of this paper is to demonstrate how to employ the Fuzzy Critical Path method (CPM) to find out airport’s ground critical operation proce...

Ground vibration is one of the undesirable results of blasting operations. Different methods have been proposed to predict and control ground vibration that is caused by blasting. These methods can be classified as laboratory studies, fieldwork and numerical modeling. Among these methods, numerical modeling is the one which saves time and cuts costs since it takes into account the basic princip...
متن کاملEmergence and Impact of Secondary Airports in the United States
As major airports in the United States have reached their maximum capacity and became congested, available capacity at surrounding airports has been utilized by the emergence of secondary airports. Given the expectation of a larger number of operations in the National Airspace System (NAS) in the upcoming years, this trend of secondary airports emergence is likely to strengthen. In order to und...
متن کاملVirtual Hubs: An Airline Schedule Recovery Concept and Model
Inclement weather at an airline's hub airport can be devastating to that airline's schedule. The repercussions resonate throughout the airline's network as capacity is reduced, connections are missed, and passengers are delayed on a larger scale than during irregular operations at a spoke airport. The main hypothesis behind the work presented in this thesis is that by shifting a small fraction ...
