Analysis of Baggage Sorting Schemes for Containerized Aircraft

Baggage transfer is a critical factor in determining connecting schedules at hub airports. This paper examines the potential benefits of “ramp transfers”-bags that bypass the hub sorting facility because they have been presorted at their point of origin. It presents three idealized baggage presorting strategies for containerized (wide-bodied) aircraft. These strategies are compared under a range of conditions, and are then integrated in a computer tool that can handle more complex problems. Presorting baggage at the origin by final destinations or groups of final destinations may be...

A new Eulerian model of airspace is derived and applied to high altitude traffic for a full air traffic control center of the National Airspace System. The Eulerian model is reduced to a linear time invariant dynamical system, in which the state is a vector of aggregate aircraft counts. The model is validated against ASDI data and applied to the Oakland airspace. The problem of controlling sector aircraft count is posed as an integer program, in which the dynamical system appears in the constraints. To improve the computational time of calculating the solution, the integer program is...
