An integrated PROMETHEE II-Roadmap model: Application to the recovery of residu...
Alves, Adriana S.F.; Nunes, Leonel J.R.; Matias, João C.O.; Espadinha-Cruz, P.; Godina, RaduRural fires are currently one of the main global disasters, and Portugal is among the countries that have suffered from them for decades. These fires pose economic, environmental, and social threats to the country. A primary cause of rural fires is the burning of biomass to clear agroforestry residues. Thus, combating rural fires requires more effective forest management, particularly the removal of forest resi...
Diagnosis and TQM Strategies for Improving the Organizational Efficiency of a C...
Pimenta, Eliana; Pimentel, Carina; Godina, Radu; Azevedo, Susana Garrido; Matias, João C. O.Total Quality Management (TQM) is useful in both the industrial and service sectors. The purpose of this study was to increase profitability at a manage-ment consulting company by applying and improving internal operational excel-lence. This was accomplished using a case study. In order to overcome the prob-lems, a prioritized plan of actions was developed by identifying the main sources of improvement. TQM str...
Boosting additive circular economy ecosystems using blockchain: An exploratory ...
Ferreira, Inês A.; Godina, Radu; Pinto, António; Pinto, Pedro; Carvalho, HelenaThe role of new technologies such as additive manufacturing and blockchain technology in designing and implementing circular economy ecosystems is not a trivial issue. This study aimed to understand if blockchain technology can be an enabler tool for developing additive symbiotic networks. A real case study was developed regarding a circular economy ecosystem in which a fused granular fabrication 3D printer is ...
Improvement of the Logistics Flows in the Receiving Process of a Warehouse
Vaz de Oliveira, Afonso; Oliveira Pimentel, Carina M.; Godina, Radu; de Oliveira Matias, João Carlos; Palavra Garrido, Susana M.Background: The present work is related to a project developed in a company dealing with the security and communication systems, fire alarms, and electronic displays sector, located in the district of Aveiro. This work aims to improve the logistics flow of material reception in the warehouse of a company by using case study research methodology. Methods: Initially, there were too many queues at reception and hi...
Influence of Orchard Cultural Practices during the Productive Process of Cherri...
Gaspar, Pedro Dinis; Godina, Radu; Barrau, RuiThis study describes the influence of orchard cultural practices during the productive process of cherries on the environmental impact in terms of energy, air, soil and water through a “farm to market” Life Cycle Assessment (LCA). The results were used to identify the orchard cultural practices that contribute significantly to the environmental impact and to find solutions to reduce those impacts, serving as be...
Life-Cycle Assessment of Dairy Products - Case Study of Regional Cheese Produce...
Nunes, Óscar Soares; Gaspar, Pedro Dinis; Nunes, José; Quinteiro, Paula; Dias, Ana Cláudia; Godina, RaduNowadays, there is a growing promotion to label products ecologically in European markets. Knowing that daily products have relevant environmental impact associated with their production, it is of utmost importance to analyse all the related production processes for a better understanding of each process impact. The present study analysed the potential environmental impacts of a Portuguese regional product, the...
Viability of Creating an Offshore Wind Energy Cluster: A Case Study
Junqueira, Helena; Robaina, Margarita; Garrido, Susana; Godina, Radu; C.O. Matias, JoãoRenewable energies play an important role in combating fossil fuels. The offshore wind sector is one of the fastest growing sectors in recent years and has attracted interest from investors and researchers, although the process is more complex and investments more expensive than onshore. Industry clusters have competitive advantages and a good opportunity for growth in the renewable energy sector. Considering t...
A comprehensive review of industrial symbiosis
Neves, Angela; Godina, Radu; Azevedo, Susana G.; Matias, João C.O.Industrial symbiosis, which allows entities and companies that traditionally be separated, to cooperate among them in the sharing of resources, contributes to the increase of sustainability with environmental, economic and social benefits. Examples of industrial symbiosis have grown over the years with increasing geographic dispersion. Thus, through a comprehensive review of previous studies, this work aims to ...
Improving airflow and thermal distribution in a real data centre room through C...
Macedo, Diogo Gonçalves Costa e Silva de; Gaspar, Pedro Dinis; Silva, Pedro Dinho da; Godina, RaduA Data Centre is a physical space that groups together computer equipment such as servers, storage arrays, among other equipment. It can be used for storage, processing and data protection. The majority of data centres operate 24 hours a day, and must provide the user with guarantees in terms of security and performance. Energy consumption is therefore permanent and the level of assistance and maintenance high....
Parametric study by means of 3D CFD to improve the airflow pattern and temperat...
Macedo, Diogo Gonçalves Costa e Silva de; Godina, Radu; Gaspar, Pedro Dinis; Silva, Pedro Dinho da; Covas, Miguel TrigueirosThe processing efficacy and energy efficiency of data centers (DC) is directly related with the cooling performance of the air-conditioning systems. The cooling effectiveness depends on airflow pattern and temperature distribution. This paper presents the parametric study of three-dimensional (3D) computational fluid dynamics (CFD) models to improve these technical characteristics. In this case study the most s...
