  • The privatization and commercialization of airports has moved forward at the globa1 level. individual countries have begun to focus less on the public welfare aspect of airports, and to emphasize the need to uncover means of increasing their respective airports economic performance and profitability. Although there is a need for Korean airports to be managed in accordance with this global trend. In order to conduct an accurate comparison and analysis of the managerial performances of the fourteen airports, the WLU(Work Load Unit) a concept which integrates the two outputs of airports, namely, passengers and freight, was employed in this study. Furthermore, in order to overcome the limitations of conducting a financial comparison based solely on WLU, the DEA model was also employed to evaluate airport efficiency: moreover, the benchmarking method was used to establish the input-output goals.

  • This study was carried out to suggest new indicators to be used at airports. Generally, passengers and cargo will be handled at the airport, and the airport will achieve revenues through them. However, all airports can not have the same distribution of passenger and cargo throughput. When comparing and analyzing several airports, a uniform result can be expected only if a unit airport throughput indicator is applied. The 'Work Load Unit' is an indicator that integrates passengers and cargo into one, and assumes that the value of one passenger is equivalent to the cargo volume of 100kg. The existing WLU was set up based on the experience at the airport rather than being established through reasonable grounds or analysis, so there was a lot of controversy. The purpose of this study is to overcome these limitations and to suggest new index. In this study, we applied a method to compare the relative value of cargo and passenger to airport revenue. In order to analyze cargo value and passenger value, airport revenues are classified into aircraft operation related revenues, passenger handling related revenues, and commercial revenues. A total of 50 airports were selected, including 14 airports in Asia, 18 airports in Europe and 18 airports in North America. According to the final analysis results, it is concluded that the cargo is equivalent to 280kg of cargo based on the contribution of one passenger averagely. This is higher than the value of 100Kg cargo per passenger.
