- Contribution of wine tourism by the implementation of an urban vineyard in a Portuguese Historic Hotel: Challenges, perspectives, and impactsPublication . Jordão, António; Barroco, Cristina; Gonçalves, TiagoWine tourism is essentially tourism in rural areas linked to wine and vineyards. However, the dissemination of viticultural heritage and wine culture with the aim of contributing to a greater connection between tourists and wine sector, even in urban environments, is an option that has been increasing in some countries. In fact, wine tourism involves a wide ecosystem of actors, which can include the hotels located in the center of the cities. In addition, inside of some cities, it could be possible for some hotels to implement small-scales vineyards. These places could represent an agricultural, historical, and cultural heritage with enormous value which could also be used for tourist purposes. Thus, the main goal of this work is to present the experience and the technical challenges during the implementation of an urban vineyard in a Portuguese Historic Hotel located in the center of the city of Viseu. In addition, the activities related with wine tourism centered on the urban vineyard are shown. The strategy for the recovery of green spaces and the hotel's communication policy are also presented and discussed.
- Enhancing Organizational Data Integrity and Efficiency through Effective Data LineagePublication . Silva, Carlos; Abbasi, Maryam; Martins, Pedro; Silva, José; ANTUNES VAZ, PAULO JOAQUIM; Mota, DavidIn the era of exponential data growth and the growing reliance of organizations on data-driven decision-making, understanding the origin, transformation, processing, and destination of data has become crucial. Unfortunately, data arriving at organizations is often incorrect or structured differently, leading to analytical errors and compromising data integrity. Without well-documented data mapping and lineage, organizations risk making strategic decisions based on flawed or inaccurate data. Consequently, the implementation of a robust Data Lineage solution has emerged as a vital component for organizational success. Such a solution not only enables error identification, but also facilitates cost reduction by pinpointing inefficient data processing points and driving efficiency improvements. However, finding the right Data Lineage solution tailored to an organization’s specific requirements remains a challenge. Therefore, it is imperative to select and implement a suitable solution that aligns with each organization’s needs.
- Health and well-being tourism: analysis of motivational factors through spa experiencesPublication . Ferreira, Jéssica; Carvalho, Cláudia; Antunes, Joaquim; Costa, João; Fonseca, Inês; Fonseca, CátiaThe increase concern about health and disease prevention and the average life expectancy increase, in developed countries, are factors that have played an important role in changing the tourist demand for health and wellness destinations segments of great importance, with a significant impact on the economy and employment in the regions (Ministry of Economy, 2021). Thus, the objective of this work is to study the motivations of tourists who seek thermal spaces, so that the managers of thermal organizations are able to respond to the new demands of the market. Based on the knowledge of the different motivations, spa organizations will be able to adjust their offer to the demand needs.
- A Hybrid Strategy for Oven Optimization in Aerospace Manufacturing: Lean Principles and Mathematical ModellingPublication . Pereira, M. Teresa; Pereira, Marisa G.; Ferreira, Fernanda A.; Silva, Francisco G.; Guimarães, AndréAdopting the Lean philosophy is essential for reducing costs and increasing productivity in industrial environments, where equipment efficiency plays a pivotal role. This study focuses on optimizing the use of an oven, a critical equipment, in the aircraft parts manufacturing process, in a company producing composite components for aerospace applications. A mathematical model based on the classic two-dimensional knapsack problem was developed to address inefficiencies in space utilization and workflow inconsistencies. The model was implemented to determine the optimal parts’ allocation, maximizing oven occupancy while ensuring efficient workflows. The study introduces a hybrid strategy that combines a structured allocation system with vertical shelving units to streamline part storage and improve the kiln-loading process. Extensive experiments validated the model’s performance, demonstrating its ability to support Lean principles by enhancing productivity and reducing costs in the aeronautical industry. This work underscores the importance of mathematical modelling for optimizing manufacturing processes and meeting the increasing demands of modern production environments.
- A Importância Da Soldadura De Termoplásticos: Um Estudo De Comparação De Processos Com Caraterísticas DistintasPublication . Trindade, Adelino; Guimarães, AndréTrês dos processos de soldadura mais utilizados na ligação de termoplásticos modernos foram analisados e comparados neste trabalho, concretamente a soldadura por gás quente (HGW), a soldadura por raio laser (LBW) e a soldadura por fricção (FSW). Os processos referidos foram utilizados na soldadura de vários materiais termoplásticos distintos, dando foco em apenas três desses materiais, tais como: polipropileno (PP), polietileno (PE) e policloreto de vinil (PVC). A qualidade obtida nas diferentes soldaduras foi avaliada recorrendo a uma análise visual, bem como através de ensaios de resistencia a tracção. Foram também realizados ensaios de dureza de Vickers ás juntas soldadas, que revelaram algumas alterações microestruturais. O estudo efetuado teve como finalidade melhorar o conhecimento dos mecanismos envolvidos na execução dos processos de soldadura utilizados e na análise da resistência das juntas soldadas.
- Industry 4.0 - Assessment of Digital Readiness of Manufacturing Companies in PortugalPublication . Guimarães, André; Reis, Pedro; Charrua-Santos, FernandoThe Portuguese industrial culture is going through some challenges and difficulties in the new phase of digitalization, using the development of several technologies that provide digital solutions aligned with Industry 4.0 (I4.0). To evaluate the digital readiness for I4.0 of industries companies, namely small, medium and large companies, a IMPULS model was used, which allowed quantifying and qualifying their level of readiness to implement I4.0 technologies, considering different dimensions and subdimensions. It is found that not all companies have the same pace and facility in adopting and implementing these technologies, where business strategies are not integrated with I4.0, resulting in the absence of an accurate selfassessment on the real maturity level achieved. Therefore, it is of great importance to understand how companies are facing different challenges and difficulties in the digital transition. This work aimed to assess the level of digital readiness to I4.0 of manufacturing companies in Portugal, in global and dimensional terms for each region. The overall assessment level is low (beginner) and the Smart Infrastructure and Data-driven Services dimensions are weak (outsider).
- Industry 4.0 in Portugal - Economic Sectors MaturityPublication . Pedro Reis; Guimarães, André; Reis, Pedro; Cardoso, Antonio J. MarquesAssessing digital maturity is critical to successfully implementing Industry 4.0 in companies. This study evaluates the digital maturity of Portuguese companies across different regions and sectors using the Shift2Future tool, a self-assessment model adapted to the Portuguese context. The model assesses six dimensions: Strategy and Organization, Smart Infrastructure, Smart Operations, Smart Products, Data-Driven Services, and Human Resources, on a Likert scale from 0 to 5. Data was gathered from 610 companies across sectors like automotive, ceramics, and metalworking through a questionnaire conducted between 2022 and 2023. Using STATA 18.0 software, the analysis included Pearson correlation and Exploratory Factor Analysis (EFA). The results indicate that companies in the North and Lisbon & Tagus Valley regions exhibit higher digital maturity. Traditional sectors like ceramics and glass show lower maturity due to technological and cultural challenges. This study evaluates the digital maturity of Portuguese businesses and suggests ways to improve their Industry 4.0 competitiveness.
- Intelligent Electric Vehicle Charging ControllerPublication . Gonçalves Cardoso, Filipe; Rosado, J.; Silva, Marco; Teixeira, C. J. Coelho; Agreira, C. I. Faustino; Caldeira, Filipe; Baptista, Pedro; Barreto, Francisco; Pereirinha, Paulo G.Abstract—For domestic consumers, electricity tariffs usually have two components: one is related to the maximum available current/total power (billed in C/day) and the other concerns to the energy consumption (C/kWh). The main switchboard current is usually limited, according to the contracted power level, by way of automatic switches. To avoid main switchboard tripping by current limit violation, Electric Vehicle (EV) owners may decide to increase their contracted power (and the energy bill) or to adopt charging strategies that limit the global consumption (EV plus house needs) to the contracted current/power. In this paper, an Intelligent Electric Vehicle Charging Controller (IEVCC), allowing to use the contracted power to the maximum extent, is presented. A set of user configurable parameters can be used to define the controller behavior, in order to prevent a full switch-off. Two versions are described: a single user version that can be used at private houses and a mesh version that can be used in multi apartment buildings, providing information about consumed energy, time of use, costs and past bills.
- The Paradox Between Concept Knowledge and Digital Maturity Level for Industry 4.0: The Portuguese CasePublication . Guimarães, André; Pereira, Rosivaldi; Pereira, Maria Teresa; Reis, Pedro; Cardoso, Antonio J. MarquesThis study investigates the paradox between theoretical knowledge of the Industry 4.0 (I4.0) concept and the actual level of digital maturity observed in Portuguese industrial companies. Specifically, it examines whether companies’ awareness of I4.0, geographic location, and size influence their capacity to adopt and integrate digital technologies. Data were collected from a sample of 450 companies through a structured self-assessment questionnaire developed in collaboration with the Shift2Future consortium. The instrument evaluated the degree of familiarity with the I4.0 concept and the stage of digital maturity across different dimensions. The statistical analysis applied ordinal logistic regression models and chi-square tests to assess three hypotheses related to the potential influence of concept knowledge, regional distribution, and company size. The results reveal no statistically significant relationship between the tested variables and the level of digital maturity, suggesting that individual factors do not primarily drive digital advancement. Instead, the findings indicate that broader structural and strategic dimensions, such as leadership commitment, participation in support programs, availability of qualified human resources, and alignment with national and European digitalization agendas, are more decisive in determining companies’ digital readiness. These results challenge common assumptions in the literature, which often posit a direct relationship between company characteristics and technological integration. The study highlights the limited predictive power of isolated variables and highlights the importance of a systemic and integrated approach to promoting digital transformation. The findings contribute to academic and policy discussions by identifying the need for more comprehensive frameworks considering the complex interplay of internal capabilities and external enablers. Future research should expand this approach by including longitudinal and sector-specific analyses and qualitative data to explore internal organizational dynamics, leadership behaviour, and employee digital literacy. The data gained can support designing more effective and inclusive digital transition strategies for industrial firms in Portugal and similar European contexts.
- Perception of the image of thermal spas in PortugalPublication . Teixeira, Francisca; Fassarela, Ana; Sousa, Alda; Costa, João Pedro; Antunes, JoaquimThe image of destinations is of great importance in the process of developing tourism for a location, acting not only as a way of differentiating itself from its potential competitors, but, mainly, as an attempt to provide economic support for the sustainable development of the destination (Chagas, 2009). The spa sector in Portugal assumes a growing importance in regions with low population density, where most of the resorts are located, as it is sometimes the main employer in the region (Hofer, et al. 2012; Costa & Antunes, 2022). Thus, the main objective of this study is to evaluate the determinants of the image of a thermal destination in Portugal, in order to improve or (re)position the image of the destination efficiently.
