航空公司因應噪音收費之最佳網路配置

Airline Network Adjustment in Response to Noise Charge

本研究在考慮環境收費與管制下探討航空公司內部化外部成本對航線頻次與機型選擇的改變，並透過噪音污染函數的計算，評估環境管制政策的有效性。本研究以一我國國籍航空公司為對象進行範例分析，驗證本研究之可行性並說明其應用價值。結果顯示航空公司可通過部分機型與頻次組合的改變以因應機場控制噪音增加之故費，而軸心機場徵收噪音費亦可能影響航空公司選擇轉運點之決策，另機場噪音量亦可因航空公司頻次與機型的重新規劃而成少，然噪音或少量的大小需視航空公司反應噪音收費重新調整的機型與頻次組合而定。

The study identifies airline cost functions and formulates an airline network design model by minimizing airline operating costs to determine the optimal air routes, flight frequencies and aircraft types in response to airport noise charge. Furthermore, the study uses equivalent steady sound level to quantify the effect of noise charge on improving the noise pollution around each airport node. A case study is provided to illustrate the application of the model and to show its usefulness. Sensitive and scenario analyses are implemented to demonstrate the effects of variations in key variables. The results show that airlines may adjust flight frequencies and aircraft types on part of their flights so as to alleviate the impacts of airport noise charge. The raised noise charge on air hubs may also affect an airline s decision on selecting its transfer airport. Finally, airport sound level can be reduced due to airlines' network adjustment, and the extent of this depends on how airlines adapt flight frequencies and aircraft types to airport noise charge
