Empirical evidence on the impact of secondary slot trading on route-level efficiency: a study of London´s heathrow airport
No full textThe existing airport slot allocation system, burdened by rising demand and limited infrastruc ture, promotes anti-competitive practices and economic inefficiencies. It allows incumbent air lines to operate inefficient "ghost flights" to retain slots, thereby deterring new entrants and
keeping slot mobility low. This master's thesis investigates a market-based alternative. Employ ing quantitative analysis, it examines the effects of secondary slot trading on the efficiency of
specific routes at London's Heathrow Airport from the summer of 2016 to the winter of 2019.
The research indicates that secondary slot trading results in greater route-level concentration
and potentially smaller aircraft sizes, suggesting negative competitive implications. Yet, it also
points out that such trading significantly expands route networks, revealing a complex balance
between market dynamism and the risk of monopolization, with further research needed to refine slot trading mechanisms

The Impact of Artificial Intelligence (AI) Replacement in Marketing - Integrating Contemporary Service Theories to Explore Stakeholder Dynamics
No full textA thesis submitted in partial fulfillment of the requirements for the degree of Doctor in Information ManagementI would like to express my gratitude to FCT Portugal (reference number 2021.09496.BD) for the financial support provided for two years of my PhD program, under the project with the following DOI: 10.54499/2021.09496.BD), https://doi.org/10.54499/2021.09496.BD
10.54499/2021.09496.BDThe rapid advancements in Artificial Intelligence (AI) in services enable companies to replace human labor with technology. Companies often adopt AI as a source of competitive advantage, forgetting about its potential detrimental impact on their employees and customers. This issue is particularly critical in the service industry, where human interaction is still highly valued. This thesis examines the impact of AI on different service stakeholders according to the Consumer–Autonomous Technology–Worker (CAW) framework and the Feeling Economy paradigm, targeting AI replacement and AI aversion in the service context, with the aim to understand the most relevant and the least jarring ways of AI integration. More specifically, a set of 12 studies, including sentiment analyses and experimental design approach, indicate that AI replacement has a negative influence on service employees but also is not perceived favorably by customers. For instance, the research demonstrates that companies’ self-promotion of AI-empowered resources (vs. human-centered resources) can reduce customers’ willingness to engage with service and can be perceived as exaggeration derived from amplified self-discrepancy. Then, the thesis reveals the negative impact of AI presence in the workplace, such as increased fear of being replaced and decreased performance due to employees’ self-comparison with AI abilities. Concurrently, customers express concern over employees being replaced by AI. Next, the research proposes an alternative to AI replacement — augmentation approach — which is perceived by customers as more enjoyable and easier to use, increasing the willingness to accept the service. Finally, the thesis provides important theoretical implications and informed practices, helping to mitigate AI’s negative outcomes on companies, employees, and customers.https://doi.org/10.54499/2021.09496.B

Integração Energética na rede de BFW do Steam Cracker
No full textA Repsol Polímeros pretende proceder à eletrificação dos compressores de Etileno e Propileno no Steam Cracker (SC). Este projeto terá impacto na distribuição e consumo de vapor, sendo que corrobora com a redução de caudal de vapor expandido pelas turbinas de expansão para a rede de condensados.
Os objetivos são estudar o impacto da temperatura da Boiler FeedWater (BFW) no consumo de fuel gas (FG) e emissões de dióxido de carbono (CO2) nas fornalhas e aquecer a corrente importada de água desmineralizada (AD) – a 25°C – através de métodos de integração energética.
A simulação da rede de condensados (antes e após eletrificação) foi feita no Aspen Hysys (AH), a análise Pinch no Aspen Energy Analyzer (AEA) e o efeito da temperatura da BFW na fornalha no Spyro.
Concluiu-se a necessidade de importar mais 50t/h de AD. O estudo revelou um aumento no consumo de FG de 1,8% (consumo de mais 3,2ktFG/ano) e um aumento de 1,3% na emissão de CO2, igual a 10,5ktCO2/ano gerando custos anuais de 2,3M€.
No âmbito do aquecimento da corrente de AD, evidenciaram-se viáveis e rentáveis propostas como: a análise Pinch ao trem de Quench Oil (QO) com excesso de vapor no futuro onde se concluiu a necessidade de um novo permutador de calor (PC); o revamping da fornalha com aquisição de um novo bundle; revisão do dimensionamento da válvula de controlo do desarejador; reaproveitamento das purgas das caldeiras com aquisição de um novo PC e, destacando-se como mais promissora, a proposta de reaproveitamento do E9101, utilizando uma corrente de processo, Quench Water (QW), com um investimento de 135k€, um VAL de 1,3M€ e um PRC de 6,2 meses.
Estudou-se a otimização do aeroarrefecedor após eletrificação, reduzindo 61% das emissões de CO2 e uma poupança de 525k€/ano. O trem de QO foi otimizado alterando o tipo de utilidade quente gerada, sendo possível prescindir de um kettle e prevenção de 48 Mcal/h de energia dissipada pelas válvulas redutoras.
A combinação das propostas recomendadas, juntamente com o projeto de eletrificação, prevê uma redução de 32% das emissões de CO2 e 23% do consumo de FG no SC, representando uma poupança de 24M€ anualmente que, comparativamente com as metas da empresa, ambiciona reduzir 30% de emissões totais de CO2 até 2030.Repsol Polímeros plans to electrify the ethylene and propylene compressors in the Steam Cracker (SC). This project is expected to impact the distribution and consumption of steam, thereby reducing the steam flow expanded by the expansion turbines into the conden sate network.
The objectives of this study are to assess the impact of Boiler Feedwater (BFW) temper ature on fuel gas (FG) consumption and carbon dioxide (CO2) emissions in the furnaces, and to explore energy integration methods to heat the imported demineralized water (AD) stream, which is initially at 25°C.
The condensate network, both before and after electrification, was simulated using As pen HYSYS (AH), while Pinch analysis was conducted in Aspen Energy Analyzer (AEA). The effect of BFW temperature on the furnace performance was evaluated using Spyro. The analysis concluded that an additional 50tph of AD would need to be imported. The study also revealed a 1,8% increase in FG consumption, amounting to an additional 3,2 ktpy, and a 1,3% increase in CO2 emissions, equivalent to 10,5 ktpy, resulting in annual costs of €2,3 million.
In terms of heating the AD stream, several viable and cost-effective proposals were identified. These include a Pinch analysis of the Quench Oil (QO) train with excess steam in the future, which indicated the need for a new heat exchanger (PC); revamping the furnace by purchasing a new bundle; resizing the deaerator control valve; reusing boiler blowdowns with the purchase of a new heat exchanger (PC) and the most promising proposal, reusing E9101 by employing a process stream, Quench Water (QW). The latter proposal requires an invest ment of €135 000, with a net present value (NPV) of €1,3 million and a payback period (PRC) of 6,2 months.
Additionally, the optimization of the air-cooler post-electrification was studied, lead ing to a 61% reduction in CO2 emissions and savings of €525 000 per year. The QO train was optimized by changing the type of hot utility generated, eliminating the need for a kettle, and preventing energy dissipation by the reducing valves.
The combined implementation of the recommended proposals, alongside the electrifi cation project, is projected to achieve a 34% reduction in CO2 emissions and a 23% reduction in FG consumption in the SC, resulting in annual savings of €24 million. These outcomes align with the company's goal of reducing CO2 emissions by 30% by 2030
