桃園國際機場環境永續發展策略性方案評估之研究

AN EVALUATION OF STRATEGICAL ALTERNATIVES FOR ENVIRONMENTAL SUSTAINABILITY DEVELOPMENT AT TAOYUAN INTERNATIONAL AIRPORT

環境永續儼然成為現代機場發展的最重要目標之一，本研究提出一分析層級架構，可協助機場單位進行初期評估之參考，該架構由建置複雜性、投入成本、改善效益和社會價值等四項構面組成，其下各有四項關鍵準則，用以評估可選擇方案的優劣。實證部分以桃園國際機場為例，透過排序成對比較法整合專家意見所得，最重要的構面為建置複雜性，16項準則中以系統建置成本、國內外跨單位合作和改善環境生態，為評估方案時最值得關注的因素。以灰關聯分析整合受訪專家對12項列舉可行方案的評估，「建設綠色航廈」、「提升機場碳排放認證等級」和「減少燃油消耗與改良油品」是桃園國際機場應優先考量推動的方向。但不同背景的受訪者觀點，仍有些許差異。

Environmental sustainability has been one of the essential development aims for modern airports. This study proposed an analytic hierarchy framework with four criteria, i.e., construction complexities, investment costs, possible improved effects, and appearance of social values. Each criterion includes four attributed sub-criteria to evaluate the priorities of selected possible alternatives in the case study for the Taoyuan International Airport (TPE). Through compiling expert opinions, the rank pair-wise comparison (RPC) results revealed that the most crucial criterion is construction complexities. System construction cost, international and domestic cross-unit collaboration, and improvement of the environmental ecology were ranked the top three sub-criteria worth noting. Results of gray relational analysis (GRA) showed that constructing green terminals, upgrading airport carbon accreditation (ACA), and reducing aircraft fuel consumption are the most adaptable alternatives for developing a sustainable TPE. However, experts’opinions from different backgrounds have little variation.
