本研究從航空業者的立場，構建一整合性資產與負債管理的資金流動模式。此模式利用時空網路定式資產與負債在不同時點之流動方式，並透過系統最佳化，求得最佳的資產與負債組合，以幫助航空業者規劃最佳的投資方式，獲得最大的利潤。在數學上此模式可定式為含額外限制式的一般化網路流動問題，屬混合整數規劃問題，本研究以一數學規劃求最佳解。為測試模式的實用績效，本研究以國內一航空業者的營運資料為例，進行測試，初步效果頗佳。 This research develops a capital flow model for air carriers that integrates assets, liabilities as various portfolios. The model employs a time-space network to formulate the flows of various assets and liabilities under different time, and then solve for an optimal combination of assets and liabilities through system optimization techniques. The model is expected to assist air carriers in determining their best portfolios in order to achieve maximum profits. Mathematically, the model is formulated as a generalized integer network flow problem with side constraints which can be characterized as a mixed integer program and be solved using a mathematical programming software. In order to test how well the model could be applied in the real world, a case study regarding the operations of a major Taiwan airline is performed. The preliminary results are good.
