航班放行公平性测量指标分析与建立

摘要

航班放行公平性是衡量民航可持续运作的重要性能指标.但与航班运行效率相比,对航班放行的公平性研究较少.为了更加直观地衡量航班放行延误的差异程度,以航空公司航班放行的公平值为研究对象,先界定航班放行公平性概念;在此基础上,结合归一化算法,首次建立了衡量航班放行公平水平的归一化指标.以首都国际机场为例,按航班放行的离港口划分4个放行方向,计算并分析4个放行方向上分别对各航空公司航班放行的公平性值.结果显示,4个方向上航班放行公平值均满足正态分布;航班放行平均公平值越高的方向,分布越不稳定.经调研验证,由该指标计算的公平值与实际运行值相符.%Equity of departure flights is an important measurement of sustainable operations in civil aviation.However studies on it are relatively rare compared with flight efficiency.In order to more intuitively measure the degree of difference in delays of departure flights, taking equity value of departure flights of different airliners as object, the concept of equity of departure flights is defined.On this basis, combined with a normalization algorithm, a normalization index is established to evaluate equity level of departure flights.The four main departure directions of Beijing Capital International Airport are taken as a case study to analyze the equity value of departure flights of different airliners.The results show that equity values of four directions obey Normal distribution.The greater the equity value is, the worse the stability becomes.Field investigation verifies that the equity value calculated by the index conforms with practical operations, which means practical.
