摘　　要：为了解决管制员在管理进近空域流量时出现实际流量低于理论流量的问题,根据运输类飞机适航标准和管制员调速规则和原则,提出了考虑下达指令时机的航段容量计算模型,由现行的进近空域结构能够发现进近空域是由多个航段连接形成了一个航路网络,根据历史统计数据得到的交通流比例,结合网络流中最大流最小割理论对进近空域容量进行评估。实例分析结果表明:在下达管制指令时间范围内,通过约束管制指令使航空器在同一减速点进行减速时,减速航段容量的最大值与最小值相差0.88架次/h,进近空域容量评估结果为:最大容量为43.79架次/h,最小容量为43.61架次/h;方法可以有效解决问题并且评估结果贴合运行实际容量。In order to solve the problem that the actual flow rate is lower than the theoretical flow rate when controllers manage the approach airspace traffic,according to the airworthiness standards for transport category aircraft and the controller's speed regulation rules and principles,a segment capacity calculation model that considers the timing of giving instructions is proposed,and the approach airspace structure can be found by the current approach airspace is connected by multiple segments to form a route network,and the traffic flow ratio obtained from historical statistics.The approach airspace capacity is evaluated by combining the maximum flow and minimum cut theory in the network flow.The results of the case study show that when the aircraft is decelerated at the same deceleration point within the time frame of the control command,the difference between the maximum and minimum value of the deceleration segment capacity is 0.88 vehicles/h.The result of the approach airspace capacity assessment is:the maximum capacity is 43.79 vehicles/h and the minimum capacity is 43.61 vehicles/h.This method can efectively solve the problem and the assessment result is the method is effective in solving the problem and the evaluation result fits the actual capacity of operation.
