Role of digital technologies to enhance the human integration in industrial cyb...
Piardi, Luis; Leitao, Paulo; Queiroz, Jonas; Pontes, JoseaneIn the digital transformation era, and particularly in Industry 5.0, humans play an active role in industrial cyber-physical systems (CPS) since they are the most flexible piece in such automated systems. However, their integration is not easy and constitutes a relevant challenge, presenting different requirements according to the activities they execute and the related integration levels, i.e., Human -in -the ...
Titanium based dry electrodes for biostimulation and data acquisition
Conselheiro, Raul; Lopes, Claudia; Azevedo, Nelson; Leitao, Paulo; Agulhari, Cristiano; Veloso, H.; Vaz, F.; Gonçalves, João Lucas; Franco, TiagoWet electrodes rely on conductive electrolyte gel for proper perfor- mance, usually presenting high setup time and being disposable or requiring time-consuming cleaning methods. Skin irritation and signal quality deterioration are some of the problems that may occur with these electrodes. Therefore, to overcome these drawbacks, 3D printed bases using Fused Deposition Modelling (FDM) with Polylactic acid (PLA), ...
Multi-agent system specification for distributed scheduling in home health care
Alves, Filipe; Rocha, Ana Maria A. C.; Pereira, Ana I.; Leitao, PauloNowadays, scheduling and allocation of resources and tasks becomes a huge and complex challenge to the most diverse industrial areas, markets, services and health. The problem with current scheduling systems is that their management is still done manually or using classical optimization methods (usually static, time-consuming) and centralized approaches. However, opportunities arise to decentralize solutions wi...
Deployment of a smart and predictive maintenance system in an industrial case s...
Alves, Filipe; Badikyan, Hasmik; Moreira, António H. J.; Azevedo, João; Moreira, Pedro Miguel; Romero, Luís; Leitao, PauloIndustrial manufacturing environments are often characterized as being stochastic, dynamic and chaotic, being crucial the implementation of proper maintenance strategies to ensure the production efficiency, since the machines’ breakdown leads to a degradation of the system performance, causing the loss of productivity and business opportunities. In this context, the use of emergent ICT technologies, such as Int...
Augmented reality system for multi-robot experimentation in warehouse logistics
Limeira, Marcelo A.; Piardi, Luis; Kalempa, Vivian Cremer; Schneider, André; Leitao, PauloThe application of tools as augmented reality has been developing innovative solutions for the industrial scenario. In this context, this work presents an industrial plant of a warehouse, where augmented reality is used to represent virtual loads to be transported by multiple small mobile robots. The results promote an application developed in ROS, with virtual and real objects sharing the same environment, pro...
Distributed scheduling based on multi-agent systems and optimization methods
Alves, Filipe; Rocha, Ana Maria A. C.; Pereira, Ana I.; Leitao, PauloThe increasing relevance of complex systems in dynamic environments has received special attention during the last decade from the researchers. Such systems need to satisfy products or clients desires, which, after accomplished might change, becoming a very dynamic situation. Currently, decentralized approaches could assist in the automation of dynamic scheduling, based on the distribution of control functions ...
A lightweight dynamic monitoring of operational indicators for a rapid strategi...
Leitao, Paulo; Rodrigues, Nelson; Ferreira, Adriano; Pagani, Arnaldo; Petrali, Pierluigi; Barbosa, JoséIn the era of the 4th industrial revolution, manufacturing companies are digitally transforming their businesses, processes and factories to address the current market demands. Among several opportunities, the dynamic monitoring of strategical indicators assume a crucial importance for the rapid awareness of the adaptation and optimization of a manufacturing process. In particular, the analysis of the effect th...
Implementation of a multi-agent system to support ZDM strategies in multi-stage...
Barbosa, José; Leitao, Paulo; Ferreira, Adriano; Queiroz, Jonas; Geraldes, Carla A.S.; Coelho, João PauloThis paper describes the development of a multiagent system (MAS) to support the implementation of zero-defect manufacturing strategies in multi-stage production systems. The MAS infrastructure, combined with on-line inspection tools, data analytics and knowledge generation, constitutes a suitable approach to integrate process and quality control in multi-stage environments. This will allow the early detection ...
