摘要
为了提高机场机位运行效率,对机位运行过程进行精确分析描述。在分析机场进出港航班机位运行流程的基础上,将机位运行过程抽象为时空关联网络,定性描述航班与机位的逻辑关系,使用航班时间窗、机位地理位置等特征参数定量描述机位运行信息,由此构建一种基于时空关联网络的机场机位运行过程定量描述模型。利用国内某大型枢纽机场实际机位运行数据对所提模型进行分析验证,结果显示,时空关联网络模型符合幂律分布,58.62%的节点平均误差为0.1724 h,节点度分布均值为0.6667,聚集系数均值为0.8075。节点度分布较高和聚类系数较高的节点为关键节点,对应影响力较大的关键航班;较现有模型,描述态势信息的宏观微观特征参数提升了场景描述精度并能有效适应数据规模的变化。
In order to improve the efficiency of the airport gate operation,this paper analyzes and describes the gate operation process accurately.Based on the analysis of the operation process of the airport inbound and outbound flights,the gate operation process is abstracted as a relational spatio-temporal network,the logical relationship between the flight and the gate is described qualitatively.The gate operation information is discribed quantitatively by using the flight time window,gate location and other characteristic parameters.A quantitative description model of airport gate operation process based on relational spatio-temporal network is proposed.The proposed model is verified by the actual gate operation data of a large domestic airport hub.The results show that,the relational spatio-temporal network model conforms to the power-law distribution,58.62%of the average node error is 0.1724 h,the average node degree distribution is 0.6667,and the average clustering coefficient is 0.8075.The nodes with higher node degree distribution and clustering coefficient are the key nodes,corresponding to the key flights with greater influence.Compared with the existing models,the macro and micro feature parameters of the situation information can improve the accuracy of scene description and effectively adapt to the change of data scale.
