Highlights Brazil is the second largest number of airports in the world. H-centrality and layer centralities rank the main point of a network. Data from 2015 and 2019 show increase of differences of main airports in Brazilian air network. Centralities methods present the Brazilian air characteristic of region concentration. Identifying main airports is important to control diseases outbreak spread.
Abstract 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.
