Stomach cancer elective surgery morbidity and mortality at 90-Day (Hold Study)
Neves-Marques, Claudia; Abulazayem, Mohamed; Wong, Geoffrey Yuet Mun; Maldonado, Ricardo David; Viswanath, Yirupaiahgari; Boddy, Alex; Donohoe, ClaireBACKGROUND: Data on multinational 90-day mortality and morbidity rates after surgery for gastric cancer is limited in the literature. This study aimed to understand the 90-day mortality and morbidity outcomes among patients undergoing elective gastric cancer surgery, as in the GASTRODATA Registry, and to identify associated risk factors. METHODS: We conducted an international prospective study on patients aged ...
Microservices architecture to enable an open platform for realizing zero defect...
Lopes, Rui Pedro; Ibrahim, Ahmed; Barbosa, José; Leitão, PauloThe market's demand for high-quality products necessitates innovative manufacturing approaches that emphasize flexibility, adaptability, and the reduction of defects. Traditional systems are currently evolving towards embracing I4.0 technologies, including data collection, processing, analytics and digital twin, aiming for zero-defect manufacturing quality. This paper introduces an open platform, compliant with...
Fairness in Designing Decision-Making Processes with Multi-Agent Systems and Hu...
Vieira, Gustavo; Zeiner, Herwig; Paletta, Lucas; Fernandes, Rui; Rosse, Higor; Sabiri, Khadija; Paz, Juan F De; Barbosa, JoséThis paper explores the integration of Human Factors (HF) into Multi-Agent Systems (MAS) to enhance fairness in decision-making processes in Industry 5.0 environments. We contribute with a human-centred perspective in the development of MAS by integrating the physiological aspects of workers in the manufacturing industry. This culminates in the measurement of human resilience. This paper presents an automotive ...
Monitoring and prediction of maintenance operations for aircraft engines repair
Mendonça, Leonardo; Pires, Flávia; Duarte, Miguel; Barbosa, José; Leitão, PauloAccurately estimating the hours required for maintenance, repair and overhaul (MRO) operations in the aviation sector frequently depends on the experience and personal judgment of engineers, can lead to introducing errors, increased operating costs, and time-consuming decision-making. This work presents the development of a cost-effective application to monitor and predict MRO operations in an aeronautical comp...
Enhancing predictive accuracy in aircraft engine mro using clustering and simil...
Mendonça, Leonardo; Pires, Flávia; Barbosa, José; Duarte, Miguel; Leitão, PauloIn the aircraft engine Maintenance, Repair, and Overhaul (MRO) process, effective task planning relies heavily on the expertise of lead engineers. However, when predictive models are used to assist decision-making, issues with incomplete, unbalanced, and inconsistent data can lead to errors in the planning task. Therefore, reliable predictions are crucial for optimising the operational efficiency. This paper pr...
Real-time rule-based monitoring tool to achieve zero defect manufacturing
Costa, Jullo; Oliveira Júnior, Alexandre de; Barbosa, José; Alves, Gleifer; Borges, Andre; Garcia, Gisela; Pires, Rui; Leitão, PauloThe demands of innovative production systems are shifting from mass production to the creation of smaller quantities with a focus on high quality. To achieve these evolving demands, Zero Defect Manufacturing has emerged as a key paradigm. This approach requires an innovative architectural monitoring tool where real-time data is continuously gathered and analysed to predict defects and assess their potential imp...
Alignment of ADACOR holonic architecture with RAMI4.0 and industry 5.0 principles
Barbosa, José; Leitão, PauloThe ADACOR holonic architecture introduced an adaptive reconfigurable manufacturing control approach that promotes a balance between centralized and decentralized control, reducing the reliance on a pure central node and enhancing the robustness, responsiveness and fault tolerance. In the digital transformation era, it is crucial to understand the alignment of ADACOR with Industry 4.0 and Industry 5.0 principle...
Design of an ISO 23247 Compliant Digital Twin for an Automotive Assembly Line
Melo, Victoria; Barbosa, José; Mota, Gonçalo; Prieta Pintado, Fernando De la; Leitão, PauloThe integration of Industry 4.0 (I4.0) technologies is transforming various society sectors, and particularly the manufacturing sector, promoting a digital transformation that fosters smart and interconnected systems. The Digital Twin (DT) acts as a key component in the digital transformation landscape and its integration with I4.0 technologies paves the way for the implementation of Zero Defect Manufacturing s...
Exploring digital twin dynamics: an analysis of structure configurations
Melo, Victória; Barbosa, José; Pires, Flávia; Prieta Pintado, Fernando de la; Leitão, PauloDigital twin (DT) is an important technology to support the realization of the digital transformation, connecting the physical asset to its virtual copy and fostering real-time monitoring, simulation, and decision-support. However, the benefits of DT depend on its intended purpose and application, which is impacted by the design structure configuration that is used for its implementation. This paper discusses t...
