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.%航班量快速增长提高了机场的机位利用密度,机位附近的滑行过程更加复杂,容易引发航班延误,必须优化航班滑行过程,减少机坪区滑行冲突.通过详细分析机坪区及其附近区域的滑行规则,归纳出实用的知识库,建立起知识库模型,再利用Java+MySql平台进行实现,最后以厦门高崎机场厦门航空公司的专有机坪和厦航的实际航班数据为仿真实例,进行系统仿真.通过比较仿真结果和机坪调度人员的实际操作,可知仿真相似度高.该研究结果是可行、有效的,能够提供机坪调度的实时方案,有利于减轻机坪调度人员的工作负荷,同时该结果也可以作为调度问题的预测等相关问题研究的参考.
