“…Annually, the ANAC (National Civil Aviation Agency) publishes the Statistical Yearbook of Air Transport, which contains statistical data on the national air transportation sector. Silveira et al (2008) investigated the efficiency of the national airlines, considering the data for the year 2005, using a methodology similar to that used in this study. The big changes that occurred in the scenario of the air transport industry in recent years motivated the realization of this study, which considers the data for the year 2008, available at www.anac.gov.br.…”

“…This article aims to investigate the performance of Brazilian airlines within the scenario described. The analysis carried out took into account the staff involved in the operation of the means of transportation, and the use of the fleet to transport cargo and passengers within national territory and internationally, as done by Silveira et al (2008). Other studies regarding operational efficiency can be found in Soares de and Araújo et al (2006).…”

The deregulation of the domestic airline industry brought a significant increase in competition between airlines, pushing them to continuously update their strategies. This article reviews the operating performance of these companies, from the contrast in the results of the DEA classic model and MCDEA-TRIMAP efficiency indicators. The use of such methodology allows the increase of discriminatory power of the productive units evaluated and a better evaluation of them. The application of the DEA model to the data from the Brazilian Airline industry for the year 2008 indicated three companies as efficient, while the use of MCDEA TRIMAP index allowed the identification of the most efficient company in 2008. The index provided better discrimination of the production units in the study.

ResumoCom a desregulamentação do transporte aéreo brasileiro, iniciada na década de 90, uma nova perspectiva de competição se desenvolveu, obrigando as empresas existentes a uma grande mudança em sua forma de posicionamento nesse tipo de mercado. Surge assim um novo conceito de voar com as companhias de baixo custo (Low Cost Carriers -LCCs) no mercado antes monopolizado pelas companhias tradicionais ou de serviço completo (Full Service Carriers -FSCs). Para garantir sua competitividade, as empresas viram-se obrigadas a buscar um melhor aproveitamento dos seus recursos. Este trabalho analisa, através do modelo DEA nebuloso, que leva em conta a má qualidade dos dados disponíveis, o desempenho das companhias aéreas brasileiras no período de 2001 a 2005. Além disso, dado que esse enfoque apresenta muitas unidades tomadoras de decisão (Decision Making Units -DMUs) empatadas, é sugerido um modelo de aumento de discriminação da análise envoltória de dados nebulosa (Fuzzy-DEA). É feita uma análise temporal dos dados de forma a avaliar a evolução das companhias aéreas frente ao novo cenário de competitividade no mercado. AbstractThe deregulation of the Brazilian aviation industry started in the early 1990s. It created a new scenario of competition for the existing carriers, forcing them to change their way of dealing with this type of market. This led to a new flying concept -the Low Cost Carriers (LCCs). Before the beginning of the LCCs operation, there were only Full Service Carriers (FSCs). In order to ensure their competitiveness, other companies were forced to seek a better use of its resources. This paper analyses -through the Fuzzy DEA model, which takes into account the poor quality of the available data -the performance of the Brazilian airlines from 2001 to 2005. Moreover, since there are many DMUs tied in this approach, a model to increase discrimination for Fuzzy DEA models was suggested. The temporal data to assess the evolution of airlines facing the new competitive scenario in the market was analysed.

“…Sobre compañías brasileñas, se encontraron dos estudios sobre eficiencia operacional [5][6] y otros dos que utilizan DEA para estudiar la estructura de capital de esas empresas [7][8]. Utilizando el modelo de Li e Reeves usado en este artículo, pero utilizando retornos constantes de escala se realizó la evaluación de las empresas aéreas por Silveira, Pereira, Correia, Soares de Mello, Clímaco y Angulo-Meza [9]. Con relación al transporte aéreo, la herramienta DEA es más utilizada para estudiar las eficiencias de los aeropuertos [10][11][12][13].…”
