A model to identify airport hubs and their importance to tourism in Brazil

Air transportation in Brazil has been recently liberalized and one of the consequences of this process is the concentration of flights in a few hubs. During the years 2006-2007 two fatal accidents created unprecedented chaos in both land and air sides of the system with harmful consequences to tourism in Brazil. The consequences were more airport congestion and many episodes of flight delays and cancellations that lasted for several months. We argue that, among other factors, this state of blackout was a result of the increase in the degree of concentration in few airports, particularly Congonhas (in São Paulo) and Brasília. Using data obtained from a survey with Brazilian experts, a comparison was made with two existing methods (the one used by the US Federal Aviation Administration and the usual Herfindahl-Hirschman method) in order to calculate the number of hubs in Brazil. Due to the huge discrepancy obtained between data from the survey and the other two methods considered, a new mathematical method based on the Herfindahl-Hirschman Index was proposed to identify the number of hubs in a given network. Drawing from the examples of what happened to tourist destinations during and after the air transport crisis in Brazil, the article concludes discussing the need for a more accurate tool to identify and to monitor the concentration of flights at the Brazilian air transportation network and its importance to tourism.

渔政船的兴波阻力数值计算与预报

渔政船是进行海上渔政监管与执法的专业船只,快速性是保证其顺利完成任务的关键因素。为了快速、准确地预报渔政船的兴波阻力,以Rankine源法和Michell积分法为基础,编制相应的数值计算程序,计算了某渔政船的兴波阻力,并将其计算结果与阻力试验值相比较,结果表明Rankine源法和试验值较为接近;再将Rankine源法与Holtrop法、Slender-body理论进一步地分析比较,发现对于高速渔政船来说,只要船体网格和自由面网格划分合理,Rankine源法在预报阻力方面优势更加突出。
