不同航班时段的收益贡献率分析

一直以来,航空公司都是根据经验来选择航班时段并确定航班时刻。事实上,航班时段的选择对增加航班收益的作用不可忽视,只依靠经验来选择时段是难以保证航班收益最大的。本文从定义航班的时段贡献率着手,用三次样条插值法对缺失数据进行插补,并应用灰色关联法进行规律同一性判断,剔除奇点数据序列,最终得出不同时段的航班收益贡献率存在明显差别,收益在相同时段则极为相近且具有相对稳定性。本文结果可以作为航空公司制定航班计划的决策依据。

Analysis on Revenue Contribution Ratio in Different Flight Time Intervals

Choosing time interval and scheduling flight play an important role in increasing airline＇s revenue. The work could not be done merely depending on the experiences to maximize the airlines’ revenues. First,a concept of contribution ratio of flight time interval wasintroduced;Then,the missing data were made up with a cubic spline interpolation method,and the law of identity was judged with the gray correlation method,meanwhile,the singularity data sequences were excluded;Finally,the differences in the revenue contribution rate on the time intervals were obtained. The results showed that the rate values kept relative stable in the same time interval. This method can be used as a basis for airlines’ scientific decision-making.
