An evaluation model of flight collaborative scheduling to guarantee flight punctuality rate

为了保障航班的准点率,对航班调度过程中空管、航空公司和机场之间的协同状况进行评价,构建一种面向航班准点率保障的航班协同调度评价模型。基于某一时间段内机场航班进港时间平均偏离值、出港时间平均偏离值、保障完成时间平均偏离值、目标撤轮挡时间准确率和计算起飞时间准确率,建立航班协同调度的指标体系;采用关联规则挖掘的方法确定各指标对航班协同调度及航班延误影响的阈值;结合模糊层次分析法和综合评价法,对各单位在航班调度过程中的协同状况给出量级评价。实验表明:该模型能够科学有效地评价各单位在航班调度过程中的协同状况,对于优化航班保障、提高航班放行正常率具有重要意义。

To guarantee flight punctuality rate and evaluate the cooperative conditions of ATC,airlines and airport in flight scheduling process,we propose an evaluation model of flight collaborative scheduling to guarantee flight punctuality rate.The model establishes the index system of flight collaborative scheduling based on flights＇ average deviation value of arrival time,average deviation value of departure time,average deviation value of flight service completion time,the accuracy rate of‘Target OffBlocking Time＇,and the accuracy rate of‘Calculate Take-Off Time＇.Firstly,the impact thresholds of each index on flight cooperative scheduling or flight delay are determined through the association rule mining method.Then,the magnitude evaluation of each unit＇s coordination in the process of flight collaborative scheduling is given through the combination of the fuzzy analytic hierarchy process and the comprehensive evaluation method.Experimental results show that the proposed model can evaluate the coordination of each unit in the process of flight scheduling scientifically and effectively,and it has great significance for optimizing flight security as well as improving the flights＇ normal releasing rate.
