Abstract:

The fast growth of flights has urged a higher rate of gates utilization,thus making taxi operations in and around aprons more complex,even leading serious flights delays. In order to reduce the conflicts of in apron area,the optimization of taxi operations becomes necessary. Based on the detailed analysis of the taxi rules in these areas,an useful knowledge base(KB)is summarized,and the KB model,realized through running on a Java-Mysql platform,is proposed. Then taking the XiaMen airlines aprons and the actual flights schedules at XiaMen GaoQi airport as an simulation example,through comparing the simulation results with the actual operations of apron,it is reasonable thus illustrating that the modeling method for the ground operations is feasible and efficient. The simulation results can provide the immediate operation method and also relieve the workload of apron controllers. Meanwhile it can be a relevance to other forecasts on apron controls or gates assignments.

Key words: gate assignment, conflicts detection and resolution, knowledge base, ground operation
