abstract

Air routes are among the most important elements of civil aviation transport. Airlines' operations are mainly dependent on the structure and layout of air routes. This paper first divides the production process of air routes into two stages, allocation and transport, based on air route operational characteristics. Then, two network data envelopment analysis (DEA) models are proposed to analyze the ef- ficiency of the system, allocation, passenger transport, and freight transport of 477 air routes. The research result demonstrates that the different constraints on intermediate measure in the network DEA models do affect the air routes’ efficiency significantly; Most air routes have high allocation efficiency and passenger transport efficiency, while they have low freight transport efficiency. Furthermore, the efficiencies of 82 airports are also analyzed after aggregating the efficiencies of the air routes.

5. Conclusion

Compared with the traditional DEA model, the network DEA model can calculate the airport's system and sub-functional effi- ciencies. This paper proposed two network DEA models to analyze the system efficiency, allocation efficiency, passenger transport efficiency, and freight transport efficiency of 477 air routes in 2013. The results show that network DEA models can help us to find the reasons for the air route’s inefficiency, and different constraints on intermediate measure in the network DEA models do affect the air route’s efficiencies significantly. The results also show that most air route’s efficiency of freight transport was much lower than its efficiency of passenger transport, and the airports with many air routes also have high efficiencies. So these results can help the governors to find the advantages and disadvantages of different functions of the airport.
