- Driving tourism development: multicriteria decision-making in Rio de Janeiro’s tourism sectorPublication . Ferreira, Fernanda A.; Coutinho, José Augusto da Fonseca Pinto; Gomes, Carlos Francisco Simões; Santos, Marcos dosAs operations stabilized after the onset of the Covid-19 pandemic, many economic sectors have gradually resumed activities, with some nearing pre-pandemic levels. Tourism is no exception, as it continues to be used as a source of resource acquisition and socioeconomic development. The purpose of this study is to promote the development of the tourism sector in the municipality of Rio de Janeiro by applying the Analytic Hierarchy Process (AHP) and AHP-Gaussian (AHP-G) multicriteria analysis methods to support potential public and/or private investments in tourism. The findings of this study will help a travel agency make a strategic decision about where to open a new branch, taking into account the sector’s potential in Rio de Janeiro. The study found that São Conrado and Ipanema are ideal neighbourhoods for establishing a new travel agency branch. Furthermore, the methodology used in this study can be used as a guideline for other organizations in the field looking to undertake similar evaluations, providing a structured approach to decision-making and investment evaluation.
- Potential challenges for the stakeholders of the tourism and hospitality sector in an increasingly digital eraPublication . Carvalho, Sandro; Sá, Carlos; Macedo, Adriana; Silva, João; Lopes, Sérgio; Ferreira, Fernanda A.; Meneses, DanielaThe tourism and hospitality sector has significantly evolved in recent years, with both public and private entities realizing its impact on local development and the country itself. Attracting tourists involves creating unique experiences, something that can be greatly enhanced through the use of the Information and Communication Technologies (ICT), especially for digital marketing and e-commerce. Actually, ICT allowed businesses to reach a wider target audience and has significantly contributed to the sector’s rapid growth. However, the use of ICT also presents risks for the various stakeholders involved. As the sector becomes highly dependent on digital platforms, it also becomes more vulnerable to cyberattacks. The widespread use of AI and IoT devices, both by individuals and in smart cities, further increases these risks. This paper examines the dangers associated with the use of ICT in the tourism and hospitality sector, from the perspective of tourists and service providers, highlighting possible privacy breaches, improper access to personal data, and fraud.
- Sequential move model for quantity and quality competition in the restaurant industryPublication . Ferreira, Flávio; Koerich, GuilhermeThis paper examines a competition in both quality and quantity between two asymmetric restaurants. The model that we consider is a Stackelberg duopoly on quantities (sequential decision-making), after a simultaneous choice of quality. Our findings indicate that the restaurant with the best reputation provides a greater variety of higher-quality food compared to its competitor. We also examine how variations in restaurants’ reputations impact market equilibrium outcomes. We demonstrate that an increase in the reputation gap between restaurants boosts the profits of both estab lishments, enhances consumer surplus, and improves social welfare. Additionally, in comparison to the scenario under the Cournot model (simultaneous decision making), small restaurant’s profits are lower under Stackelberg model, while the opposite holds for the large restaurant’s profits and for social welfare.
- Supporting digital nomads’ city choice using AHP-Gaussian and MABACPublication . Silva, Renato; Gomes, Carlos; Santos, Marcos dos; Ferreira, Flávio; Ferreira, Fernanda A.The phenomenon of digital nomadism has been gaining prominence worldwide, driven by advances in communication technologies and the growth of remote work. Choosing an ideal city to live in is a complex decision, involving multiple quantitative and qualitative factors. This study applies a hybrid multicriteria decision-making approach, combining the Analytic Hierarchy Process—Gaussian (AHP-Gaussian) for determining criteria weights and the Multi-Attributive Border Approximation Area Comparison (MABAC) method for ranking alternatives. Data were obtained from the Kaggle platform, covering 15 cost-of-living criteria for 50 cities worldwide. The AHP-Gaussian method reduces subjectivity in weight assignment, while MABAC ensures stable and reliable rankings even with variations in the dataset. The combined application of these methods allows digital nomads to make better-informed choices aligned with their personal and professional priorities. The results point to Seattle (USA) as the most suitable city among those evaluated, followed by Atlanta and Washington, both also in the USA. The study demonstrates that the hybrid approach is an effective and replicable decision support tool in contexts with similar decision-making needs.
