To reduce the workload of air traffic operators in airport surface operation, curtail the cost of taxi-out and the pollutant emission, a new gate-hold penalty-based departure pushback control strategy was proposed based on the traditional N-control strategy. The algorithm could search the optimal threshold for taxiway queuing system, and require the pushback rate changes with the real-time taxiway queue length. Taken the pushback operational cost as objective function, the control strategy model and its two various forms were carried out, and an iterative Markov chain-based optimization algorithm was developed to solve the model. Simulation results with PEK airport data indicate that the proposed pushback strategy could transfer taxiway waiting time into gate-hold time to minimize the total operational cost. The strategy could save 2995 minutes per day on total taxi-out time and 44.04% fuel burn cost than situation of without pushback strategies, also reduce departure operational cost effectively.%为减少飞机离港过程中调度者的工作负担,降低滑行成本及污染排放,在飞机离港过程传统N控制策略基础上,提出一种基于停机位等待惩罚的推出控制策略.这种策略可以为滑行道排队长度搜寻最优阈值,并且要求推出频率随当前滑行道排队长度实时变化.建立以推出成本为目标的推出控制模型及其两种变体形式,设计了一种基于连续时间马尔科夫链的迭代优化算法.首都机场实际推出数据仿真结果表明:所提出的推出控制策略能有效地将滑行等待时间转化为停机位等待时间,总滑行等待时间减少了2995 min/d,燃油消耗比无推出策略条件下减少44.04%,离港燃油成本大大降低.
