The development of air transport industry contributes to the economic growth worldwide. It evolves from a luxury form of transportation to an affordable and quick way to move between places. The airline operation model evolves from a traditional point-to-point operation to a hub-and-spoke model, where airline funnels passenger through a centralized location called hub. This model, while reducing operational cost and increasing connectivity, is also adding more time and distance to one’s journey. The development in aircraft technology however, allows airline to by-pass the traditional hub and fly directly to their destination with a longer-range aircraft with a low capacity, somehow returning to the original operational model of point-to-point flight. However, this new type of aircraft also allows airline to reach a smaller destination that didn’t justify the use of the high-capacity aircraft that was traditionally used on this long-haul flight. Aside from the lower acquisition cost, this smaller aircraft also burns less fuel and reduce the airline financial risk.   The study was focused on locating a new hypothetical hub to connect Europe with Eastern Asia, the top two aviation market by passenger number. This new hub will be strategically located between the two markets, unlike the current Middle-Eastern hub that requires a significant detour. The Buffer Tool that is available in ArcGIS will be utilized to draw a radius between each airport in the study area, where the radius’ values were based on the range of the Airbus A321NEO (New Engine Option). Area with the most intersection will be further analyzed to determine the most reasonable location for the new hub, based on the airport infrastructure and the country’s socio-economic index.   The result of this study shows that the Central Asian region has the most overlapping circle, with the city of Almaty in Kazakhstan emerged as the most potential location for this new hub. The geographical advantage, backed by a relatively strong economy and stable socio-political condition, made Almaty left the other candidates behind.

Yes / With China being the world’s largest emitter of greenhouse gases and its aviation sector burgeoning, the environmental performance of Chinese airlines has global significance. Amidst rising demands for eco-friendly practices from both customers and regulators, the interplay between airport infrastructure and environmental performance becomes pivotal. This research offers an innovative methodology to gauge the environmental performance of Chinese airlines, emphasizing the distance traveled between airports using weighted additive utility functions. Leveraging neural networks, the study investigates the impact of various airport infrastructural characteristics on environmental performance. Noteworthy findings indicate that ground control measures, automatic information services at origin airports, surface concrete on runways at both ends, and a centerline lighting system in destination airports positively influence environmental performance. In contrast, longer and wider runways at origin airports, increased distances to control towers, and asphalt runways at destination airports adversely affect it. These insights not only underscore the importance of strategic infrastructure enhancements for reducing carbon footprints but also hold profound policy implications. As global climate change remains at the forefront, fostering sustainable airport infrastructure in China can significantly contribute to worldwide mitigation efforts. / The full-text of this article will be released for public view at the end of the publisher embargo on 18 Jan 2025.

EUROPEAN AIR HUBS IN THE CONTEXT OF NETWORK AND ITS RESISTANCE AGAINST DISTURBANCES Abstract The submitted master thesis is addressing the theme of connectivity of European Air Transport Network, its properties and resistance against negative influences based on data from flight schedules for winter season 2018. The main objective of the thesis is to analyse European Air Transport Network from the point of connectivity in order to find out the most important airport hubs according to their geographic conditions, community structure and resistance of the whole network. Used methods are based on the Graph Theory and the centrality measures as indicators of connectivity. The empiric part of the thesis is divided into three parts. The aim of the first part is to find out, what airports are the most important in the European Air Transport Network. In the second part are explored properties and structure of the network. The last part is aiming to analyse the resistance of the European Air Transport Network from the view of robustness and resilience. Among the most important air hubs in Europe belong airports, that are serving world cities and tourist attractive localities. There is a strong dominance of the Schiphol airport in Amsterdam, the El Prat airport in Barcelona and the Frankfurt Airport. The European Air...

[pt] Nesta dissertação, estuda-se a discriminação de preços no transporte aéreo brasileiro. A base de dados, construída a partir das respostas dos passageiros na Pesquisa O/D, contém informações a que as companhias aéreas não têm acesso. Passageiros com maior renda e que viajam a trabalho pagam preços maiores, e o uso de vários controles nas regressões permite concluir que isso é explicado, em parte, por discriminação de preços. Desenvolve-se um modelo empírico de discriminação de preços, em que uma firma utiliza os atributos das passagens para prever a disposição a pagar dos consumidores e, assim, estabelecer os preços. Empregando as estimativas dos parâmetros do modelo, consideram-se cenários contrafactuais em que há restrições sobre a discriminação de preços. Em média, restringir a discriminação de preços geraria uma redução do excedente do consumidor da ordem de 10 por cento. / [en] This dissertation studies price discrimination in the Brazilian airline market. The data used are from the O/D Survey, which involved interviews with passengers. This enables us to have in our data set information that airlines do not have. Business travelers and those with higher incomes pay higher prices. By including several controls in the regressions, we obtain evidence that this is due to price discrimination, at least to some extent. We develop an empirical model of price discrimination, in which a firm uses ticket attributes to predict consumers’ willingness to pay and thus sets its prices. The model’s estimated parameters are used to construct counterfactual scenarios where price discrimination is constrained. On average, restricting price discrimination would reduce consumer surplus by approximately 10 per cent.

Like every public place, airport terminals have always been vulnerable to all kinds of crimes. In addition, terminal security concerns not only encompass the fight against acts of terrorism, but also involve problems that may adversely influence the operations of the airport. This work aims to present a model, based on computational simulation of passenger service process from a safety inspection of the airport terminal of Goiânia. It was develop a combined method, based on a quantitative method to deal with measurable elements with a qualitative method to assess the complexity of the problem analyzed. Through the simulation, using Flexsim software it was modelled the inspection system of an airport security, leading to conclusions that the characteristics of passengers directly influence the processing times in the system. In this regard, it was noted the lack of information regarding the procedures that passengers should adopt in relation to their belongings and clothing during the crossing of the airport security system. / Devido ao crescimento da quantidade de viajantes no transporte aéreo em todo o mundo, faz-se necessário implantar um controle eficiente do fluxo de passageiros nos processos internos dos terminais aeroportuários. Como todo local público, os terminais aeroportuários sempre são vulneráveis a todos os tipos de crimes. Além disso, as preocupações da segurança do terminal não englobam somente a luta contra atos de terrorismo, mas também problemas que podem influenciar negativamente as operações do aeroporto. Nesse contexto, este trabalho tem o objetivo de apresentar um modelo, baseado na simulação computacional, do processo de atendimento de passageiros do ponto de inspeção de segurança do terminal aeroportuário de Goiânia. Para atingir seus objetivos foi construído um método combinado, de natureza quantitativa para lidar com elementos mensuráveis do processo de inspeção de segurança, com uma análise qualitativa, destinada a avaliar mais profundamente a complexidade do problema. Através da simulação realizada no software Flexsim, foram obtidos resultados estatísticos de desempenho do sistema de inspeção de segurança do aeroporto, permitindo concluir que as características dos passageiros influenciam diretamente os tempos de processamento no sistema. Nesse sentido, foi constatada a falta de informações a respeito dos procedimentos que os passageiros devem adotar em relação aos seus pertences e vestimentas durante o atravessamento no processo de inspeção.

O setor de transporte aéreo brasileiro apresenta uma dinamicidade socioespacial que está relacionada à atuação e às ações estratégicas desenvolvidas pelas companhias aéreas em múltiplas escalas territoriais. Este trabalho se propõe analisar e discutir as estratégias empresariais no setor de transporte aéreo brasileiro considerando as principais companhias do país, pois são essas que empreendem uma constante dinâmica a partir de ações estratégicas que promovem a concorrência e a competitividade, mas que também se consubstanciam por estratégias de cooperação. Ao analisar a reprodução do capital empresarial, este trabalho discute as estratégias de três das principais companhias aéreas brasileiras que concentram a maioria dos voos realizados no país, sendo: a TAM Linhas Aéreas, a GOL Linhas Aéreas Inteligentes e a AZUL Linhas Aéreas Brasileiras. Considerando a integração entre a dinâmica do capital e a dinâmica territorial, defendemos a tese de que há uma indissociabilidade na relação entre as ações do capital empresarial em determinados territórios e aeroportos que constituem o interesse das principais companhias aéreas brasileiras. O objetivo primordial das empresas aéreas é buscar e garantir um maior alcance do seu poder de atuação territorial. Assim, essas ações estratégias são desenvolvidas para obter e deter o domínio, a supremacia de expansão do poder territorial, daí a constante necessidade de se promover acordos e alianças com outras companhias. Diante dessa abordagem, somam-se elementos como: a concorrência, a competitividade, a cooperação, a distribuição das malhas aéreas e a definição dos principais hubs aeroportuários, as concessões de aeroportos à iniciativa privada e a participação e influência das ações do capital estrangeiro. Em síntese, esses elementos constituem um conjunto de referências para analisar e discutir as ações do capital empresarial integrada à busca por poder de atuação territorial. / The Brazilian air transport sector has socio-spatial dynamics that are related to the performance and strategic actions developed by the airlines at multiple territorial levels. This study aims to analyze and discuss the business strategies in the Brazilian air transport sector considering the leading companies in the country, for these are the agents that engage in a constant and relevant dynamic based on strategic actions that promote rivalry and competition, but that are also supported by cooperative strategies. By analyzing the reproduction of business capital, this work discusses the strategies of three Brazilian companies that operate most flights in the country, namely: TAM Linhas Aéreas, GOL Linhas Aéreas Inteligentes and AZUL Linhas Aéreas Brasileiras. Considering the integration between capital dynamics and territorial dynamics, we defend the thesis that there is an inseparable link between the effects of business capital and certain territories and airports, which constitute the fundamental interests of the main Brazilian airlines. The primary objective of these companies is to pursue and ensure an increase in their potential territorial range. As such, these strategic actions are developed to obtain and hold the command, the supremacy over the expansion of territorial power. It is this that gives rise to the constant need to promote agreements and alliances with other companies. This approach is supplemented by such elements as: rivalry, competition, cooperation, distribution of air networks, definition of the main airport hubs, public concessions of airports to private companies, in addition to the participation and influence of foreign capital. In summary, these elements constitute a set of references to analyze and discuss the effects of business capital integrated with the search to control territorial range.

The search for a sustainable competitive advantage has become a concern of organizations toward the market actualities. This research assessed the competitiveness related to the costs of logistics processes of the air transportation for the watches industry at the Manaus Industrial Hub - Polo Industrial de Manaus (PIM). This survey was conducted through qualitative, exploratory, documental and sampling (accessibility and convenience) methods, where 80% of the population answered questionnaires, with a confidence interval of 99%. Two questionnaires were used: the first collected data regarding logistics costs of participating companies and the second collected data regarding the perception of the same population regarding the avaliation of competitiveness related to the logistics costs. Logistical factors, identified through the existing relationship between suppliers and customers, were based on the Supply Chain Operations Reference (SCOR) model, through the movements between inputs and outputs of finished goods, identified in logistics processes of transport, handling, storage and clearance, being the calculation done through activity-based costs method (ABC). More than 70% of companies bring their supplies using domestic air transportation. For international supplies, 42% of companies use the sea and air multimodality and 32% use only air transportation. For transportation of finished products in the domestic market, 99.7% of companies use air transportation. The months of October and November were considered as the “high season”. The seasonality of the retail sector directly impacts the purchase of watches, mainly on special celebrations as the Mother's Day, Valentine's Day and Christmas. Regarding costs, the shipping cost is the most important one, accounting for more than 85% of the total cost, followed by 6.7% at warehouse processes, 4.8% for local transportation and 2.4% of customs clearance. Thus the total logistics costs in “high season” is R$ 6.1 million, which represents 7.7% of revenues in the sector. Conclude that logistics costs in 2013 affected the competitiveness of these companies, because in the most part of the respondents opinion, watches companies located at PIM has no competitive logistics costs, considering the reality of each company, the economic scenario at PIM and national and international economic scenario as well. The reduction of logistics costs, reduction of tax burden, mainly related to the cost of personnel could help to the reduction of this indicator. Another factor that would help to the reduction of logistics costs in air transportation would be the investments in infrastructure, with bigger volume of funds invested and more quality as well. As a practical contribution, it is proposed that the model might be used as a tool for assessing logistics costs of companies. The research can be justified as per interest of the academic community, in order to develop methods for verification and management of logistics costs related to the evaluation of the competitiveness of companies. / A logística tornou-se uma atividade primária de grande importância, atribuindo aos custos logísticos o fator chave de competitividade. A busca da vantagem competitiva sustentável tem se tornado uma preocupação das organizações perante as realidades do mercado. Esta pesquisa avaliou a competitividade em relação aos custos dos processos logísticos do modal aéreo para o setor produtor de relógios do Polo Industrial de Manaus (PIM). A pesquisa foi realizada por meio dos métodos qualitativos, exploratórios, documental e amostrais por acessibilidade e conveniência, onde 80% da população respondeu o questionário, com intervalo de confiança de 99%. Foram aplicados dois questionários, sendo que o primeiro consistiu na coleta de dados sobre os custos logísticos das empresas participantes e o segundo na coleta da percepção dos respondentes quanto a avaliação da competitividade em relação aos custos logísticos. Os fatores logísticos identificados por meio da relação existente entre fornecedores e clientes foram fundamentados no modelo de referência Modelo de Referência para Operações na Cadeia de Suprimentos (SCOR), através das movimentações de entradas e saídas de produtos acabados, identificados nos processos logísticos de transporte, movimentação, armazenagem e desembaraço, sendo o cálculo realizado por meio do método de custeio por atividades. Mais de 70% das empresas transportam os insumos nacionais pelo modal aéreo e nos insumos internacionais, 42% usam a multimodalidade marítimo e aéreo e 32% usam o aéreo. Para o transporte de produtos acabados no mercado nacional, 99,7% das empresas usam o modal aéreo. Os meses de outubro e novembro foram considerados os de maior movimentação. A sazonalidade do varejo impacta diretamente o setor de relógios, principalmente nas datas comemorativas, tais como: dia das mães, dia dos namorados e Natal. O custo de transporte é o mais relevante, correspondendo mais de 85% do custo total, seguido de 6,7% nos processos de armazenagens, 4,8% em movimentação e 2,4% de desembaraços aduaneiros. Assim, os custos logísticos totalizam no mês de maior movimentação R$ 6,1 milhões, representando 7,7% do faturamento do setor. Conclui-se que os custos logísticos de 2013 afetaram a competitividade destas empresas, pois na opinião da maioria dos respondentes, as empresas de relógio do PIM não possuem custos logísticos competitivos, considerando os cenários da própria empresa, do setor no PIM, nacional e internacional. A redução dos custos com logística e a desoneração da carga tributária, vinculada principalmente ao custo de pessoal poderiam contribuir na redução deste indicador. Outro fator que contribuiria para a redução dos custos com logística no modal aéreo seria a realização de investimentos em infraestrutura, com maior volume de recursos aplicados e mais qualidade. Como contribuição prática propõe-se que o modelo seja usado como instrumento de avaliação dos custos logísticos de empresas. A pesquisa pode ser justificada quanto ao interesse da comunidade acadêmica em desenvolver métodos sobre apuração e gestão de custos logísticos relacionados à avaliação da competitividade de empresas.

[pt] O paradigma da vantagem competitiva e da visualização da arena de negócios como um campo de batalha, questionado desde o seu auge, na década de 80, vem sendo revisto à medida que novas configurações organizacionais, de caráter colaborativo, têm sido adotadas pelos agentes econômicos como forma de lidar com a complexidade que tem norteado o ambiente em que se encontram inseridos. O tema tem sido alvo de um expressivo número de publicações, e crescentes esforços têm sido destinados à investigação do impacto da adoção de estratégias colaborativas no desempenho das firmas participantes. Na indústria de transporte aéreo, também a formação de alianças de múltiplos parceiros, ou constelações, tem despertado o interesse de pesquisas nesse sentido. Esse trabalho soma-se a essas pesquisas, tendo por objetivo investigar o impacto da adoção de alianças estratégicas no desempenho das companhias aéreas que aderiram às grandes constelações formadas na década de 90. Trata-se de uma pesquisa empírica, em que foram comparados, por métodos quantitativos, os indicadores de desempenho de 18 firmas da indústria nos períodos definidos como anteriores e posteriores à adesão às alianças, com base no banco de dados da ICAO- International Civil Aviation Organization. Constatou-se que a simples adesão a constelações não garantiu desempenhos isolados superiores. No entanto foi observado que em alguns casos, em função das estratégias colaborativas adotadas no conjunto, as empresas acabaram por obter ganhos significativos de desempenho. / [en] The competitive advantage archetype, as well as the idea of considering the management as a battle field, have been questioned since its height, in the eighties. These ideas have been being reviewed as new organizational configurations, with collaborative nature, have been adopted by the economic agents as a manner to deal with the complexity that has signed the environment in which they are living in. The theme has been focus of a significant number of studies and growing efforts have been dedicated to evaluate the impact of adopting collaborative strategies on the member firms performance. In the global airline industry, also the formation of multiple partners alliances, or constellations, has received the attention of researches with the same purpose. This work sums to these researches, aiming to investigate the impact of the adoption of strategic alliances on the performance of the airlines that joined the big constellations formed in the nineties. It is an empirical research, in which have been compared, using quantitative methods, the performance measurements of 18 firms of the industry, in the periods defined as previous and subsequent to the embracing to alliances, based on data of ICAO - International Civil Aviation Organization. Among the main achievements, was found that just joining a constellation did not guarantee superior isolated performances. Nevertheless, was observed that, in some cases, due to the whole collaborative strategies used, firms ended having significant performance gains.
