基于交叉航段间隔损失的终端区进口点容量计算

Capacity Calculation of Terminal Area Arrival Fix Based on Interval Loss of Crossing Route

终端区容量的有限性使得终端区空域成为非常宝贵的资源,而终端区交叉航段是影响终端区容量的一个重要因素。明确终端空域中交叉航段的容量,确定终端空域进出口点的容量,对于空域资源的合理利用具有重要意义。建立平面交叉航段容量模型与终端区进口点最大流网络模型,用Ford-Fulkerson算法求解出终端区进口点的容量。以西宁机场11号跑道进场程序为算例,求得终端区各进口点的容量及跑道容量,算例结果与TAAM仿真模型结果相近,验证了模型的有效性,并且可以高效、直观地求解终端区进口点容量。

The limited terminal area capacity makes the terminal airspace to be a very valuable resource,and the crossing route is a crucial factor to affect the terminal capacity.It is of great significance for the rational utilization of airspace resources to determine the capacity of the terminal airspace crossing routes and the arrival fix.This paper establishes the capacity model of the plane crossing route and the maximum flow network model of the terminal area arrival fix,and solves the capacity of the terminal area arrival fix by Ford-Fulkerson algorithm.Finally,given an example of the standard approach procedures of runway 11 of Xining airport,the capacity of each arrival fix and runway calculated by these models is close to TAAM simulation model.The validity of the model is verified,and the capacity of arrival fix in the terminal area can be efficiently and intuitively solved.
