飞行频率、拥挤成本和互补型航空联盟：中枢轮辐网络机场拥挤分析

摘要

This paper comprehensively analyses the airport congestion in hub-and-spoke network based on flight frequency,congestion cost and complementary airline alliances.We find that there is an overprovision of flight frequency and aircraft size is suboptimal,hence the aggravated problem of congestion.At the same time,we find that the flight frequency is positively related to airlines＇congestion cost and the disutility of schedule delay is negatively related to aircraft＇s fixed cost.Complementary airline alliances lead to a higher profit;the price is lower for connecting passengers and higher for local passengers;complementary airline alliances can also internalize the congestion faced by partner airlines,optimize flight frequency and weaken congestion.%本文在基于飞行频率、拥挤成本和互补型航空联盟的基础上系统分析了中枢轮辐网络机场拥挤问题。研究表明：航空公司的利润最大化使得航班飞行频率存在过度供给,飞机大小也是次优的,这进一步恶化了中枢机场的机场拥挤;航班飞行频率与航空公司的拥挤成本系数、旅行计划延迟效用系数正相关,与飞机每次起降的固定成本负相关;互补型航空联盟使得联盟体利润增加,航空联盟对连接市场乘客有利,对本地市场乘客不利,航空联盟还可以内化伙伴间拥挤,航班飞行频率得以优化,机场拥挤得以缓解。
