Abstract:

Gate assignment is one of the important tasks in Airport Operation Center (AOC). A logical gate assignment method could decrease airline'delay time and improve operation benefit as well as service quality. A method of gate assignment is introduced aiming at the maximum utilization ratio of the near gates and the minimum ambulation distance for the transfer passengers. An optimized algorithm for preparative gate assignment is also proposed according to the distribution and attribute of gates in airports. Based on those results,a gate reassignment method is designed against the interferential problem caused by delayed aircraft. The calculation result shows that this method provides a valuable reference for improving the assignment efficiency in AOC,enhances the operation benefit and service quality simultaneously,as well as solves the interference to the pre-assignment problem caused by delayed aircraft at a certain extent.
