Optimal airside reassignment following temporary incidents with variations in arrival or departure times

Abstract

We develop an integrated model for gate, taxiway, and runway reassignments following airside incidents such as temporary gate closures, taxiway closures, or changes in wind direction. We consider changes in aircraft ground movements and times due to these temporary incidents and variations in arrival or departure times. An airside network is developed to model runway, taxiway, and gate operations. Arrival, departure, and transit aircraft airside operations are considered simultaneously. The results indicate that taxiway and gate closures always have a negative influence on airside ground operations, but a change in wind direction does not follow any specific trend. In addition, a gate closure has a greater negative influence than a taxiway closure, by as much as 19% for a 10-hour closure.
