本文将航空公司的能效评估分为四个阶段：运营阶段、机队维护阶段、服务阶段和销售阶段。新的四阶段航空公司能源效率网络结构是对现有模型的修改。采用基于网络损耗和基于网络损耗的方法，对19家国际航空公司2008 - 2014年的整体能效和部门能效进行了评估。通过回归分析，分析了航空公司能源效率的影响因素.结果表明：1.综合模型可以在整个系统和各个阶段识别出对标航空公司。2.在此期间，大多数航空公司的能源效率保持稳定，除了一些急剧波动。受美国金融危机的影响，效率下降主要集中在2008-2011年。3.船队平均船龄与总体能源效率正相关，各分部效率有不同的显著影响因素。
This paper focuses on evaluating airline energy efficiency, which is firstly divided into four stages: Operations Stage, Fleet Maintenance Stage, Services Stage and Sales Stage. The new four-stage network structure of airline energy efficiency is a modification of existing models. A new approach, integrated with Network Epsilon-based Measure and Network Slacks-based Measure, is applied to assess the overall energy efficiency and divisional efficiency of 19 international airlines from 2008 to 2014. The influencing factors of airline energy efficiency are analyzed through the regression analysis. The results indicate the followings: 1. The integrated model can identify the benchmarking airlines in the overall system and stages. 2. Most airlines' energy efficiencies keep steady during the period, except for some sharply fluctuations. The efficiency decreases mainly centralized in the year 2008–2011, affected by the financial crisis in the USA. 3. The average age of fleet is positively correlated with the overall energy efficiency, and each divisional efficiency has different significant influencing factors.
