Analysis of airport APM systems using a computer simulation model

Lin, Yi-Dar 10 January 2009 (has links)
Automated People Movers (APM) have become an attractive solution to problems associated with the concept of airside/landside airport development. This technology, if used effectively, could provide an acceptable level of service to airport users and a good operating efficiency to airports and airlines. The main objective of this research is to develop a computer simulation model to simplify the operational analysis of airport APM systems and to assess their level of service characteristics. The model simulates the movement of individual passengers and vehicles in the system network, and provides a tool for planners and designers: (1) to determine the sensitivity of system performance for a range of APM design parameters, (2) to examine the flexibility of an APM system under given operational policy and network configurations, and (3) to estimate the APM vehicle energy consumption based on network constrains and system characteristics./p> The model is a discrete-event simulation model developed using EXTEND (Version 3.0.2, © Imagine That, Inc., 1994) software. With the powerful features of animation, graphics, and hierarchical modeling, the EXTEND libraries provide the capability to easily model alternative service concepts such as shuttles, loops, and single or double routes. / Master of Science

A Simulation Study on Baggage Screening at San Luis Obispo County Regional Airport

Ott, Marian 01 March 2021 (has links)
Efficient passenger flow is a crucial objective at both small and larger airports. One central part of this is the handling of checked luggage which is influenced by necessary security screening. Within this thesis, these processes are studied at San Luis Obispo County Regional Airport. The underlying problem of the airport is its outbound luggage system which was already suffering from delays prior to Covid-19. Delays were never measured and the bottleneck responsible for them was never identified. However, expected growth in passenger and flight volume necessitates to predict when customer dissatisfaction and extensive luggage delays are inevitable, given that the airport does not plan to change the baggage screening system in the near future. In order to understand the dependencies within said system, process flowcharts for baggage-related activities are defined and translated into a simulation model. After model verification and validation, scenarios of expanding the flight schedule during different times of the day are tested while monitoring the number of bags failing to be loaded into the respective aircraft in time. Further scenarios of model adjustments are used to monitor how the number of missed bags changes while maintaining an expanded flight schedule. Model adjustments were made by changing single parameters such as the scan time or single resources each. Simulation experiments have shown that the number of additional flights that can be added to the flight schedule of February 2020 depend on the time of the day. For instance, the current outbound luggage conveyor system’s capacity is sufficient to cover 1 additional early morning flight, and up to 3 afternoon flights. Experiments with model parameter adjustments led to identifying the luggage scanner as the bottleneck of the luggage system, whereas other tested parameter adjustments showed to have minimal impact on the number of missed bags. Since the model’s flight plan can be conveniently adjusted in the connected Excel database, the model could be used as a tactical decision tool for capacity analysis.

Strange Measure

Horst, Aaron M. 25 October 2006 (has links)
To bring movement into architecture, that eluding fixity into that fixed. The thesis begins here, in paradox, a paradox continuing throughout, in the form of various oppositions -- movement and stasis, the impulsive and the graphic (the graph), measure and disorder (or measured disorder). The very form of an 'opposition,' and its subtext of mutual exclusion restated as an entwined tension, an impossible one-within-the-other, thought if not realized, oblique if not overt. To work with flight, architecturally, with the movement of people and objects, departure and arrival, and, as architecture, with enclosure and disclosure. The experience of air travel, specifically the boundlessness of one's gaze when in flight paired with the aircraft's insularity, interested me initially as a metaphor. To inhabit the infinitude of the sky within a protective vessel, moving through, and suspended within, space, extending the boundaries of the subject. Each scale -- the scale of expanse, and the human scale of the aircraft -- opposite yet enmeshed, the aircraft physically, sensorially, framing the boundless. Aside from scale, the earlier question of movement, transience, within this expanse. Transience as flux, flux as that antithetical to architecture's fixing in time, even as time is expressed. A way to think while working -- to 'think' expanse while working with enclosure, to 'think' the meander while outlining the static. The struggle between impulse and order, between ordered impulse and harmonic proportion, symmetry and the meander. Allowing a strange measure, indeed, cultivating this irregular growth, a graphing of impulse, an impulse to graph. / Master of Architecture

Avaliação da qualidade dos serviços aeroportuários considerando a perspectiva das Companhias Aéreas

Botero Pérez, Cindy January 2016 (has links)
Este trabalho tem como objetivo principal a avaliação de qualidade dos serviços aeroportuários considerando a perspectiva das Companhias Aéreas. Para tanto, o trabalho visa: (i) propor um modelo baseado em atributos de qualidade para os serviços prestados pelos gestores dos aeroportos às Companhias Aéreas; (ii) realizar a implementação desse Modelo para a avaliação da qualidade de ditos serviços; e (iii) avaliar a qualidade dos serviços oferecidos tanto para passageiros quanto para Companhias Aéreas. Assim, dois Modelos são propostos e aplicados, o primeiro com foco em Companhias Aéreas e o segundo que integra as perspectivas delas e dos passageiros, com relação aos serviços comuns. A construção dos Modelos foi baseada na revisão da literatura e no conhecimento de especialistas dos setores de aeroportos e serviços. A implementação dos modelos foi realizada em dois Aeroportos da América do Sul, um no Brasil e outro na Colômbia, abrangendo os pontos de vista dos atores: Gestores de Aeroporto, Companhias Aéreas e passageiros. Assim, foi possível analisar os aspectos que esses atores valorizam, sua percepção sobre a qualidade e, ainda, proceder a uma análise de gaps. A inclusão do ponto de vista das Companhias Aéreas na avaliação da qualidade dos aeroportos representa uma contribuição à literatura, devido à pouca quantidade de trabalhos sobre o assunto e a importância dos aeroportos atenderem esses clientes. Na prática, os modelos apresentados podem ser usados pelos gestores dos aeroportos como ferramentas para a avaliação de seus serviços, análise do conflito de interesses, integração das perspectivas de passageiros e Companhias Aéreas, e identificação de oportunidades de melhoria. / This paper aims to evaluate the quality of airport services considering the Airlines perspective. Thus, this paper intends to: (i) propose a Quality Attributes-based model for services provided by the Airport operator to airlines; (ii) implement a model for the quality evaluation of those services; and (iii) evaluate the quality of the services provided to passengers and airlines. Two models were proposed and implemented, the first had a focus on airlines and the second integrated the perspectives of airlines and passengers in respect of common services. The models were built based in the literature review and the knowledge of airport and services experts. The implementation of these models was done in two South America airports, one in Brazil and other in Colombia, comprising the point of view of airport managers, airlines and passengers. Consequently, it was possible to analyze the items they value, their perception about quality attributes and also to conduct a Gaps analysis. The inclusion of airline’s point of view in the airport quality assessment represents a contribution to the literature, due to the small amount of papers on the subject and the relevance of these clients. In practice, the proposed models can be used by airport managers for assessing their services, analyzing the conflict interests and the integration between the passengers and airlines perspectives; and identifying opportunities for improvement.

No. of bitstreams: 1 Gerson Moura Duarte.pdf: 6944260 bytes, checksum: 79e21dba34c1b315c04972e1a4a5b07f (MD5) Previous issue date: 2012-02-06 / Fundo Mackenzie de Pesquisa / In the globalized era the contemporary airport is strategic since it connects one country to the global world. This study deals with the relationship between the São Paulo International Airport and the town of Guarulhos, where it is located, and the outcomes in the São Paulo metropolitan region. Studying the City Master Plan and the laws concerning land usage and occupation in the town of Guarulhos we found out that, between 1980 and 1990, the urban planning instruments were permissive to clandestine and irregular urban residential occupation in the surroundings of the airport. And that, even after it became more restrictive concerning this kind of land usage since 1990 the municipal authority did not impede, or did not have the conditions to impede, the growth in population density in zones improper for urban residential occupation and incompatible with the airport operation of the main Brazilian international airport. The Airport Master Plan, delivered in 1981, was devised by the Federal Government through the Coordinating Comission of the Airport System Project COPASP; and the Airport Development Plan, ended up in 2004, by INFRAERO, did not consider the resettlement of about 5 thousand families that lived nearby the future third landing-strip, jeopardizing the continuity of the airport implementation as designed. We understand that the contemporary airport should be considered strategic to the city, the region and the country where it is located and therefore its implementation should be shared with the territory that encompasses it. / O aeroporto contemporâneo na era da globalização é estratégico, pois, conecta um país ao mundo global. Este trabalho trata da relação entre o Aeroporto Internacional de São Paulo e a Cidade de Guarulhos que o acolheu, e os seus desdobramentos na Região Metropolitana de São Paulo. A partir do estudo dos Planos Diretores e das Leis de Uso e Ocupação do Solo de Guarulhos constatamos que, entre 1980 e 1990, os instrumentos de planejamento urbano dessa cidade foram permissivos em relação às ocupações urbanas residenciais clandestinas e irregulares no entorno do aeroporto, e que mesmo após terem se tornado mais restritivos em relação a esse uso, a partir de 1990, o poder público municipal não impediu, ou não teve condições de impedir, o adensamento populacional em zonas de usos impróprias para ocupações urbanas residenciais e incompatíveis com a operação aeroportuária do principal aeroporto internacional brasileiro. O Plano Diretor Aeroportuário, elaborado em 1981; foi realizado pelo Governo Federal através da Comissão Coordenadora do Projeto Sistema Aeroportuário COPASP; e o Plano de Desenvolvimento Aeroportuário, concluído em 2004, pela INFRAERO, não considerou o reassentamento de aproximadamente 5.000 famílias que residem nas áreas de aproximação das cabeceiras da futura terceira pista de pouso e decolagem comprometendo a continuidade da implementação desse aeródromo como fora planejado. Entendemos que o aeroporto contemporâneo deve ser considerado estratégico para a cidade, a região e o país onde está inserido e, portanto, deve ser implementado de forma compartilhada ao território que o acolhe.

Effects of CEO Changes on Senior Management Leadership Teams of U.S. Airports

LaRoche, Gale Larine 01 January 2016 (has links)
Changes in the top leadership position in U.S. airports occur frequently. The purpose of the present phenomenological study was to understand the shared, lived experiences of senior managers who work in a U.S. airport and who have undergone a change in the top leadership position. Airports are of critical importance to their local regions and communities and are economic engines for their respective regions. The results of the study may provide positive social change for airport staff and the surrounding community by drawing attention to the complexity in leadership transition. The study was grounded in organizational stress, uncertainty theory of stress, and person-environment fit theories. A purposive sampling method was used to recruit 11 participants who were senior managers at a U.S. airport and experienced a change in the top leadership position within the last 6 years. The interview data were analyzed using interpretive phenomenological reduction methods of epoche, eidetic reduction, and imaginative variation. Findings revealed that transitional leadership resulted in positive effects such as self-efficacy beliefs, commitment, and job satisfaction; it also resulted in negative effects such as disengagement, which appeared to be mediated by the active roles leaders took in meeting employee needs. Participants who valued their skills and contributions were better able to cope with changes and were more confident about their employment ability. This study contributes to positive social change by providing information for airport board members and staff to improve the process of hiring a CEO.

Travellers’ preference for parking at the Vancouver International Airport

Romank, Heather 11 1900 (has links)
Market research is becoming an increasingly important part of an airport's operational strategies as airport managers try to increase customer service and reach operational goals. This research applies conjoint analysis to investigate customer preferences for parking facilities and services at a major Canadian airport. This research will define and determine the relative importance of a set of attributes which influence business travelers' parking choice at the Vancouver International Airport. In addition, market segments for parking services will be identified. Sawtooth Software's Adaptive Conjoint Analysis and Ci2 were used in this study. A questionnaire was administered to a 36 employees among three local companies selected for data collection. Employees of these three companies represented potential local business travelers. This study was limited to the investigation of a subset of traveler (i.e. business traveler) preferences for parking at the Vancouver International Airport. More complete analysis would have to replicate the data collection procedures and target different users under different conditions (i.e. time of day, time of year, duration of stay). Results of the conjoint analysis indicated that price and distance to the terminal building account about equally for the majority of business travelers parking preference ratings (approximately two-thirds). The provision of video camera security was also an important determinant of customer preference. The provision of electronic signage providing guidance to available parking spaces did not contribute significantly to customer preference. In addition, the provision of a parkade rather than a surface lot contributed little to customer preference. Market share estimates were calculated for YVR's proposed Parkade, Main and Economy parking lots. Estimates of market shares suggested that a majority of business travelers taking an overnight journey in August preferred to park in the YVR Parkade. Market share estimates were also calculated for various service alternatives in the parkade. Comparing these additional estimates with the base service option revealed the trade-offs that business travelers were likely to make. Results anticipated approximately a 60 percent market share for the proposed parkade service despite charging a higher price ($6 per day higher than the alternative parking lots). Market share estimates predicted that the provision of video camera security and electronic signage in the parkade was significant in enabling a higher price. The predicted market share falls substantially to 28 percent if security and signage are not provided. Results also suggested that more travelers were willing to pay extra for the provision of video camera security than electronic signage in the parkade.
