Comparative evaluation of the Brazilian air transport system centrality

This work seeks to analyze the centrality of the Brazilian airport commercial system and compare flights data of 2015 and 2019. This paper is an extension and updated study from article presented at VII RIDITA (Pereira et al., 2019). We evaluated the Brazilian airport system by the results of layer centrality and h-centrality. These methodologies of centrality, unlike other traditional methods in graphs theory, try to evaluate the comprehensiveness of each vertex (in the case of the airport) and the influence on the others in the network. The results show the main characteristic of the Brazilian airport system regarding the concentration of the operation in regions and airports. Central airports demand greater attention from the agents in several operational fields (maintenance, traffic control, mobility, etc.) to raise the quality of the system.
