This thesis proposes that a baggage handling system (BHS) environment can be defined and coupled to a whole life cycle cost (WLCC NPV) model. The results from specific experiments using the model can be used as the basis by which to commercially compare BHS flight build types of any capacity, and BHS geographical location. The model examined the three flight build types(i): Fully automatic build2; (ii) Semi-automatic build, and(iii); Manual build. The model has the ability to calculate a bag flow busy hour rate, and to replicate the baggage flow characteristics observed within real BHS operations. Whole life cycle costs (WLCC NPV) results are produced, and these form the basis by which the comparison of BHS types is made. An overall WLCC NPV scatter diagram was produced, which is a summation of each of the test sensitivities. The assumptions and limitations of the analysis are provided. It is proposed that the results, conclusions and recommendations shall be of value to airports, airlines, and design consultants.

Summary Aim: The aim with the study was to explore the work conditions of the Ground staff performing unloading and loading from an HTO perspective, and to identify areas for improvement. Research questions: 1. Which factors are important for the work performance? 2. To what degree do the employees follow the work instructions regarding the use of the equipment on the ramp? 3. Which recommendations can be provided to improve work performance at ramp operations and minimize risks for accidents? Background: Ramp operations have, according to Studic et al., (2017), repeatedly been estimated as one of the areas with the highest, still increasing, safety risks. Passenier, Sharpanskykh and de Boer (2015) also confirms how the work within the ramp operations, and performance of unloading and loading, is an area with high risks of injuries and deaths. Methods: The study was conducted with a qualitative research approach and Descriptive Case study design (Baxter & Jacks, 2008). Results: Five categories were found; time pressure, “safety mindset”, education, culture and equipment. The findings also showed that the employees prioritize the safety of the aircraft rather than their own safety. Conclusions: Out of the five factors, time pressure and equipment are the factors in the environment which the respondents have to work in line with to make it function in the environment.

Peruvian Airport Company (en adelante PAC) es la empresa a la cual se le ha adjudicado la concesión del mantenimiento, ampliación y administración del Aeropuerto Internacional Kuntur (en adelante AIK). De acuerdo con el contrato de concesión y el Plan de Desarrollo mínimo para la modernización de la infraestructura aeroportuaria, PAC está obligado a cumplir con hitos de inversión y mejoras obligatorias relacionadas con el incremento de las operaciones aeroportuarias. Para poder cumplir con ello, se busca que para el año 2022 el sistema actual incremente su capacidad de procesamiento de equipajes de 1,735 a 3,229 equipajes/hora en horario de máxima demanda. Mediante la implementación del programa “Mejoras en el sistema de transporte de equipajes” se busca ampliar y mejorar el sistema actual y evitar “cuellos de botella” y picos de demanda que podrían generar reclamos por parte de las aerolíneas y multas por incumplimiento de parte del organismo regulador (OSITRAN – MTC). Este programa está conformado por cuatro proyectos: Upgrade del sistema de máquinas de rayos X, Mejoras en el sistema de transferencia, Trabajos de Infraestructura y Ampliación e instalación de fajas transportadoras. El proyecto objeto de estudio del presente trabajo de investigación, es la Ampliación e instalación de fajas transportadoras en las zonas 01 a la 07 y deberá ser ejecutado en 453 días, desde el 06/02/2017 hasta el 31/10/2018. Se proyecta un valor actual neto de U$ 1,679,821 utilizando la tasa de retorno WACC de 9.26% y un presupuesto de $. 4,744,521. / Peruvian Airport Company (PAC) is the company that has been awarded the maintenance, expansion and administration of Kuntur International Airport (AIK). In accordance with the concession contract and the Minimum Development Plan for the modernization of airport infrastructure, PAC is obliged to comply with investment milestones and mandatory improvements related to the increase airport operations. In order to comply with this, the current system should process approximately 3,229 bags/hour during peak demand hours by 2022; however, it currently only processes 1,735 bags/hour. The implementation of the "Improvements in the baggage transport system" program seeks to expand and improve the current system and avoid "bottlenecks" and spikes in demand that could lead to airline claims and fines for non-compliance by the regulatory body (OSITRAN – MTC). This program involves four projects: Upgrade of the X-ray machine system, Improvements in the transfer system, Infrastructure Works and Expansion and installation of conveyor belts. The project under study covers only the supervision of the expansion and installation of conveyor belts in zones 01 to 07 and should be implemented in 453 days, from 06/02/2017 to 29/10/2018. A net present value of $1,679,821 is projected using WACC return rate 9.26% and a budgeted amount of $. 4,744,521. / Trabajo de investigación

<p>The purpose of this master thesis has been to develop a baggage handling process at Stockholm Skavsta Airport that is cost-efficient, in order to prepare for the expected expansion of the airport. When developing the new process it was a directive to examine the possibilities of using radio frequency identification, RFID, technology and also that the required investment for the new process should have a payback time of no more than two to three years. The current process contains a completely manual sorting activity, which is both costly in terms of personnel and creates some mishandling of baggage due to the human factor. Our recommendation is a baggage handling process that use automatic sorting through RFID technology that eliminates the mishandling of baggage and reduce the personnel costs and at the same time have a payback period of less than three years. The main cost driver is the RFID tag costs and therefore our process is a so called closed-loop system, where the tags are reused several times and require very little work in between uses. The proposed physical layout consists of a drawing of the physical layout of the baggage sorting hall, a description of the RFID system, and the required information system software.</p>

This researcher describes the characteristics of place...physical, cultural and human...of a small Kentucky county and looks at the incidence of disease and dying that occurred in that place in the last half of the nineteenth century. The impact of death on particular subsets of the general population was given a closer evaluation. Very young, females and the slave/Black communities were investigated individually. The overall site and situation of all aspects of Trimble County, Kentucky were viewed in an effort to support the notion that it is the manner in which man interacts with this environment that causes disease and death and that is not the environment itself that destroys human life.

Zur schnellen und sicheren Gepäckabfertigung ist eine Automatisierung der Gepäckprüfung zweckmäßig. Es wird eine mehrstufige Prüfung des Gepäcks durchgeführt. In der ersten Stufe werden vom Gepäckstück mehrere Röntgendurchstrahlungbilder angefertigt. Bei einem Teil der Gepäckstücke wird ein kritischer Bereich festgestellt, welcher mit einer zweiten Maschine genauer untersucht werden muss. Aus diesem Grund muss durch die zweite Maschine anhand nur eines weiteren Röntgendurchstrahlungsbildes erkannt werden, wo sich der kritische Bereich nach dem Transport durch das Förderband befindet. Zur Lösung dieses als Positionswiederfindung bezeichneten Problems wurde ein Verfahren entwickelt, welches auf einer Beziehung zwischen den Momenten der Grauwertverteilung des Durchstrahlungsbildes und den Momenten der Schwächungskoeffizentenverteilung des Objektes beruht. Das Verfahren wurde anhand von simulierten Beispielen getestet. / Automatic explosive detection is advantageous for fast and secure baggage control. The baggage is controlled by a multi level system. In level 1 the baggage will be inspected by a multi view x-ray radiography machine. The machine divides the baggage into secure and rejected bags and finds in the rejected bags a critical region for further inspection by a level 2 machine. For this reason the level 2 machine has to identify by only one additional x-ray view the new position of the critical region of the bag after the transport to the level 2 machine. To solve this problem a method was developed, which uses a relation between the moments of the grey-value of x-ray scan and the moments of the x-ray attenuation coefficient of the inspected object. The method was tested with simulated scans.

Utilizando dados sobre o preço de passagens aéreas vendidas divulgados nos Microdados da ANAC, estimo regressões sob diferentes especificações de efeitos fixos e variáveis de controle para avaliar o impacto da cobrança da taxa de bagagem sobre tarifas. Na especificação que julgo mais adequada para lidar com possíveis endogeneidades, encontro uma redução média de R$ 14,85 no preço da tarifa. Em seguida, realizo estimativas da demanda por passagens aéreas em um modelo logit e do efeito da taxa de bagagem sobre a valoração do consumidor / The main objective of this dissertation is to study the impact of baggage fees adoption on the level of airline tickets prices and the behavior of consumers. Using microdata on the price of airline tickets published by ANAC (the Brazilian airlines regulator), I estimate regressions under different specifications of fixed effects and covariates to evaluate the impact of baggage fee adoption on prices. In the specification that I argue as the most appropriate to avoid possible endogeneities, I find an average reduction of R$14.85 in the price of airline tickets. Next, I develop estimates of the demand for airline tickets under a logit model and the effect of baggage fee adoption on consumer’s utility.

A large part of people's lives are spent in indoor spaces such as office and university buildings, shopping malls, subway stations, airports, museums, community centers, etc. Such kind of spaces can be very large and paths inside the locations can be constrained and complex. Deployment of indoor tracking technologies like RFID, Bluetooth, and Wi-Fi can track people and object movements from one symbolic location to another within the indoor spaces. The resulting tracking data can be massive in volume. Analyzing these large volumes of tracking data can reveal interesting patterns that can provide opportunities for different types of location-based services, security, indoor navigation, identifying problems in the system, and finally service improvements. In addition to the huge volume, the structure of the unprocessed raw tracking data is complex in nature and not directly suitable for further efficient analysis. It is essential to develop efficient data management techniques and perform different kinds of analysis to make the data beneficial to the end user. The Ph.D. study is sponsored by the BagTrack Project (http://daisy.aau.dk/bagtrack). The main technological objective of this project is to build a global IT solution to significantly improve the worldwide aviation baggage handling quality. The Ph.D. study focuses on developing data management techniques for efficient and effective analysis of RFID-based symbolic indoor tracking data, especially for the baggage tracking scenario. First, the thesis describes a carefully designed a data warehouse solution with a relational schema sitting underneath a multidimensional data cube, that can handle the many complexities in the massive non-traditional RFID baggage tracking data. The thesis presents the ETL flow that loads the data warehouse with the appropriate tracking data from the data sources. Second, the thesis presents a methodology for mining risk factors in RFID baggage tracking data. The aim is to find the factors and interesting patterns that are responsible for baggage mishandling. Third, the thesis presents an online risk prediction technique for indoor moving objects. The target is to develop a risk prediction system that can predict the risk of an object in real-time during its operation so that the object can be saved from being mishandled. Fourth, the thesis presents two graph-based models for constrained and semi-constrained indoor movements, respectively. These models are used for mapping the tracking records into mapping records that represent the entry and exit times of an object at a symbolic location. The mapping records are then used for finding dense locations. Fifth, the thesis presents an efficient indexing technique, called the $DLT$-Index, for efficiently processing dense location queries as well as point and interval queries. The outcome of the thesis can contribute to the aviation industry for efficiently processing different analytical queries, finding problems in baggage management systems, and improving baggage handling quality. The developed data management techniques also contribute to the spatio-temporal data management and data mining field. / Doctorat en Sciences de l'ingénieur / info:eu-repo/semantics/nonPublished
