考量到離場航班銜接下桃園國際機場機門指派之研究

Gate Assignments Considering Connections between Arrival and Departure Flights at the Taiwan Taoyuan International Airport

由於機場民營化與航空公司專屬機門使用的趨勢，機門指派作業逐漸朝向以機場管理者改變為由航空公司進行規劃。其中，以航空公司觀點，相同航機到離場航班若能於同一機門銜接，則可減少到離航班之拖機次數，降低航空公司的場站費用。另外，此種指派方式亦可減少航機使用機門時間，增加航空公司其專屬機門的使用容量。因此，本研究以航班銜接最大化為目標構建一機門指派模式，以反應航空公司實務營運之考量。本研究以數學規劃方法，運用網路流動的技巧，建立一班機到離網路架構，以構建此模式。最後，本研究以國內某航空公司於桃園國際機場的營運資料為例，並參考目前指派作業設計兩情境進行測試分析，結果顯示本研究模式在不同情境下皆可有效率求得最佳解。另外，與目前機場主管當局之指派作法相較下，本研究模式確實可求得一較多航班銜接數之機門指派結果，提升航空公司之機門指派績效。

Because of the trend of airport privatization and airline-specific gates, gradually airport gate assignment will be performed by airlines instead of airport authorities. In particular, from airlines' perspective, if arrival and departure flights with the same aircraft can be connected at the same gate, then the towing of airplanes can be decreased, so as to reduce airlines' station expenses. In addition, it can reduce the time block for flights assigned to gates and thus increase the capacity of the airline-specific gate. Therefore, this research develops a gate assignment model with the objective of maximizing the number of arrival and departure flight connections to reflect airlines' considerations in actual operations. We use mathematical programming methods, coupled with network flow techniques, to develop an arrival and departure flight network for the model. Finally, two scenario tests are performed concerning the current assignment operations and the data of a Taiwan airline at the Taiwan Taoyuan International Airport. The test results show that the model can effectively obtain optimal solutions under different situations. In addition, comparing with the current gate assignment by the airport authority, the model can obtain a gate assignment with more arrival and departure flight connections to enhance the performance of the airline's gate assignment operations.
