Researchers are applying more holistic approaches to the feedback control of the air transportation system. Many of these approaches rely on economic feedback, including the cost of delays to the airlines. Establishing an accurate mechanism for estimating the cost of a delays for each portion of a flight (gate costs, taxiing in and out costs, and en-route costs) is useful for many aspects of mo...

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 ...

The Economic Partnership Agreements (EPAs) between the group of African, Caribbean and Pacific (ACP) countries and the European Union could serve as an opportunity to accelerate global and regional trade integration of ACP countries. Moreover, the European Commission intends to use EPAs as a tool for development and the eradication of poverty in ACP countries. To achieve their potential develop...

The aim of the work is to develop conceptual directions for structure formation and number airline’s fleet based on satisfying consumer preferences enterprises-customers helicopter operations. helicopters currently in operation cannot fully satisfy requirements customers terms their flight technical economic characteristics, which leads a decrease use it negatively affects economy airline corre...

Schedule development is typically the first phase of the airline planning process. We present a framework for perturbing scheduled departure and arrival times after a crew schedule has been found. We characterize perturbations that keep a schedule legal while not increasing the planned cost of the crew schedule. We show that when random delays occur in operations, the expected cost can be reduc...

Business intelligence in a future global air traffic management can be accomplished via integrated and intelligent operational decision support technology for airports and airline operators, air traffic controllers and pilots. It aims to support decisions regarding the management and the control of the global traffic flows, of the capacity of the airports and of the global air space-time resour...

A necessary step when developing next generation systems is to understand the tasks that operators will perform. One NextGen concept under evaluation termed Single Pilot Operations (SPO) is designed to improve the efficiency of airline operations. This SPO concept includes a Pilot on Board (PoB), a Ground Station Operator (GSO), and automation. A number of procedural changes are likely to resul...

Granularity is an integral feature of temporal data. For instance, a person’s age is commonly given to the granularity of years and the time of their next airline flight to the granularity of minutes. A granularity creates a discrete image, in terms of granules, of a (possibly continuous) time-line. We present a formal model for granularity in temporal operations that is integrated with tempora...
