摘要: 为促进提高终端区空域管理水平,定量评估终端区空域利用率,基于终端区的运行情况构建了终端区利用率的评估体系;基于熵值法建立终端区空域利用率灰色计算模型,来克服传统评估方法中权系数确定不客观的缺点;选取国内某个典型的国际机场的终端区一天的数据为基础,对每小时的利用率进行评估,得到了该终端区每小时的利用情况以及变化趋势。研究表明:评估结果与实际运行情况接近,能突出体现终端区利用率一天的变化情况以及不正常天气对利用率的影响。

Abstract: In order to promote airspace management level of terminal area and quantitatively evaluate the utilization rate of terminal area airspace, an evaluation system of utilization rate of terminal area was constructed based on the operation conditions of terminal area. Based on the entropy method, a gray calculation model of airspace utilization rate of terminal area was established to overcome the shortcomings of the traditional evaluation method that the weight coefficient was not objective. Based on the data of one day in the terminal area of a typical international airport in China, the hourly utilization rate was evaluated, and the hourly utilization rate and the trend of the terminal area were obtained. The research shows that the evaluation result is close to the actual operation, which can highlight the change of utilization rate in the terminal area in one day and the influence of abnormal weather on utilization rate.

Key words: air transportation, air traffic management, terminal area, airspace utilization rate, entropy method
