On the Integration of Industrial Data and Analysis with Simulation in a Company...
Mesquita, C.; Vieira, António; Dias, L.; Pereira, Guilherme; Oliveira, José A.Nowadays, companies are constantly seeking to develop tools to increase productivity, production flexibility and the quality of their products, or to reduce costs, delays and their exposure to risks. In fact, such improvements can be achieved in the scope of product as well as of process improvement. In industrial contexts, often, such improvements can be achieved by implementing tools to access the intended in...
Empowering deaf-hearing communication: Exploring synergies between predictive a...
Adão, Telmo; Oliveira, José A.; Shahrabadi, Somayeh; Jesus, Hugo; Fernandes, Marco; Costa, Ângelo; Ferreira, Vânia; Gonçalves, Martinho FradeiraCommunication between Deaf and hearing individuals remains a persistent challenge requiring attention to foster inclusivity. Despite notable efforts in the development of digital solutions for sign language recognition (SLR), several issues persist, such as cross-platform interoperability and strategies for tokenizing signs to enable continuous conversations and coherent sentence construction. To address such i...
Assigning products in a Vertical Lift Module supermarket to supply production l...
Vieira, António Amaro Costa; Dias, Luis S.; Pereira, Guilherme; Oliveira, José A.This paper presents the development of a mathematical model for product assignment in a Vertical Lift Module (VLM), which are increasingly em-ployed in the industrial sector due to their advanced technology and efficient parts-to-picker process. Mathematical modelling plays a crucial role in address-ing the complexity of these problems and providing intelligent and innovative solutions. Despite being a tactical...
Activity based simulation - A modeling tool for new teaching-learning strategies
Pereira, Guilherme; Vieira, António Amaro Costa; Machado, Ricardo J.; Ferreira, Bruno Lourenço Silva; Dias, Luis S.; Oliveira, José A.Teaching and learning Discrete Event Simulation (DES) at universities within the context of undergraduate studies in industrial and engineering management is not thoroughly covered in the literature. In fact, most strategies tend to solely address commercial tools, resulting on too much focus on syntax, semantics and getting used to the interface of a particular tool, rather than on simulation fundamental conce...
Stakeholder Management in University-Industry Collaboration Programs: A Case Study
Fernandes, Gabriela; Capitao, Marlene; Tereso, Anabela Pereira; Oliveira, José A.; Pinto, Eduardo B.Poor stakeholder management repeatedly comes up as one of the main reasons for unsuccessful projects. This issue takes a higher dimension when we look at the inter-organizational context, where traditional stakeholder management practices may be insufficient. This paper investigates stakeholder management applied to the context of collaborative research and development (R&D) programs between university and indu...

Thermal stability and decomposition kinetics of NdNiO3− δ at 1 bar of O2
Bassou, A. A.; Machado, P. J.; Gomes, M. M.; Manjunath, B.; Vilarinho, R.; Silva, Bruna Andreia Nogueira Airosa; Oliveira, José A.; Almeida, B. G.Despite the interest in rare-earth nickelates for applications, their processing under 1 bar of oxygen pressure is still challenging. In this work, we report the co-precipitation synthesis, thermal stability and thermally driven decomposition of NdNiO3 phase, in order to determine the synthesis parameters towards a pure perovskite phase. We concluded that using a 1% molar excess of Nd during preparation and pos...
Supply chain data integration: a literature review
Vieira, António Amaro Costa; Dias, Luis S.; Santos, Maribel Yasmina; Pereira, Guilherme; Oliveira, José A.Supply chains (SCs) are dynamic networks subject to uncertainties and risks that may occur anywhere, anytime, and whose consequences affect the entities that comprise such SC, possibly affecting others. In fact, there are several examples wherein the occurrence of certain events resulted in considerable costs. Thus, it is important to ensure that SCs can apply preemptive measures, rather than just react to disr...
Are simulation tools ready for big data? Computational experiments with supply ...
Vieira, António Amaro Costa; Dias, Luis S.; Santos, Maribel Yasmina; Pereira, Guilherme; Oliveira, José A.Peer-review under responsibility of the scientific committee of the International Conference on Industry 4.0 and Smart Manufacturing. The need and potential benefits for the combined use of Simulation and Big Data in Supply Chains (SCs) has been widely recognized. Having worked on such project, some simulation experiments of the modelled SC system were conducted in SIMIO. Different circumstances were tested, in...
Bypassing data issues of a supply chain simulation model in a big data context
Vieira, António Amaro Costa; Dias, Luis S.; Santos, Maribel Yasmina; Pereira, Guilherme; Oliveira, José A.Peer-review under responsibility of the scientific committee of the International Conference on Industry 4.0 and Smart Manufacturing. Supply Chains (SCs) are complex and dynamic networks, where certain events may cause severe problems. To avoid them, simulation can be used, allowing the uncertainty of these systems to be considered. Furthermore, the data that is generated at increasingly high volumes, velocitie...
