为缓解机场场面拥堵,提出基于弹性滑行容量的飞机推出控制策略.提出飞机推出时隙的概念,分析推出时隙的特性及其与滑行容量之间的关系;提出弹性滑行容量的概念,并进一步设计了飞机有效推出时隙的确定方法,建立了以飞机离港成本最低为目标的飞机推出模型.利用Arena软件对新郑国际机场飞机离港流程进行了仿真.结果表明,高峰时段平均轮候时间由6.2min降至1.0min,场面拥堵大大降低,离港成本下降19.3%;全天推出114架飞机中,平均推出延误时间3.8min,推出延误超过15min的飞机仅占4.4%.
In order to alleviate the congestion of airport surface,an aircraft pushback control strategy based on elastic taxiing capacity is explored.The concept of the"aircraft pushback slot"is proposed,and the characteristic of pushback slot is analyzed.The concept of"elastic taxiing capacity"is put forward,and the calculation method of aircraft effective pushback slot is further designed.Then,an aircraft pushback model for minimizing the total cost of departure process is established.A simulation is performed on Xinzheng International Airport with Arena.The result shows that the average waiting time during rush hour is reduced from 6.2min to 1.0min,the congestion is alleviated,and the total cost is decreased by 19.3%.Among the 114 departures of the whole day,the average pushback delay is 3.8min,and the proportion of pushback delays which exceeding 15 min only account for 4.4%.
