航班延误给旅客出行造成不便也增加了航空公司的运营成本。在航班地面等待过程中,维持机舱供电的成本是延误损失的重要组成部分。通过考虑不同供电方式完善了航班延误成本模型,提出了客舱等待容忍时限概念,深入分析了使用廊桥静变电源和APU(飞机辅助发动机)供电时,航班总地面延误成本随时间的变化趋势。在对航班延误成本量化分析的同时,讨论了在客舱内实施地面延误的极限时间。以B737-800、A320和B747-200三种主流机型为例,采用本文模型对延误成本、延误损失比例、客舱等待容忍时间进行计算机仿真模拟,结果表明,本文模型能量化分析航班地面延误成本,能反映廊桥静变电源供电的经济优势,能为航空公司优化运营成本提供可靠工具。
The inconvenience caused by delayed flights to passengers also increases the operating costs of airlines. During the waiting on the flight floor, the cost of maintaining engine room power is an important part of the delay. By considering the different power supply modes, the flight delay cost model is improved and the concept of waiting time of cabin waiting is put forward. The trend of the total cost of ground flight delays with time is analyzed in detail when using the power supply of the bridge static power supply and APU (aircraft auxiliary engine). While quantifying the delay cost of flight, the paper discussed the limit time of implementing ground delay in passenger cabin. Taking B737-800, A320 and B747-200 three mainstream models as an example, this model is used to simulate the delay cost, the delay loss ratio and the waiting time of waiting in the cabin. The results show that the model can quantify the flight delay cost , Can reflect the economic advantages of corridor static power supply, can provide reliable tools for airlines to optimize operating costs.
