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...
Dynamic monitoring of key-performance indicators in industrial environments
Pereira, Arnaldo; Petrali, Pierluigi; Pagani, Arnaldo; Barbosa, José; Leitão, PauloManufacturing companies generate huge amounts of relevant data that, potentially, can help the decision makers to monitor and supervise the health status of the shop-floor. Many problems are present that prevent this monitoring, namely the identification of which data should be collected, how to execute this collection or how this data should be analysed and displayed to the user. This paper deals with the last...
Multiagent system integrating process and quality control in a factory producin...
Leitão, Paulo; Rodrigues, Nelson; Turrin, Claudio; Pagani, ArnaldoManufacturing companies are currently forced to reconsider their production processes by adopting more flexible, robust, and adaptive systems, aiming to improve their competitiveness. Multiagent systems (MASs) technology is suitable to address this challenge by providing an alternative way to design these complex systems based on the decentralization of the control functions over distributed entities. This pape...
Intelligent products: the grace experience
Leitão, Paulo; Rodrigues, Nelson; Barbosa, José; Turrin, Claudio; Pagani, ArnaldoProduct intelligence is a new industrial manufacturing control paradigm aligned with the context of cyber-physical systems and addressing the current requirements of flexibility, reconfigurability and responsiveness. This paradigm introduces benefits in terms of improvement of the entire product׳s life-cycle, and particularly the product quality and customization, aiming the customer satisfaction. This paper pr...
Multi-agent system for integrating quality and process control in a home applia...
Leitão, Paulo; Rodrigues, Nelson; Turrin, Claudio; Pagani, ArnaldoA current trend in manufacturing is the deployment of modular, distributed and intelligent control systems that introduce adaptation facing unexpected deviations and failures, namely in terms of production conditions and product demand fluctuation. The integration of quality and process control allows the implementation of dynamic self-adaptation procedures and feedback control loops to address a large variety ...
Implementation of a methodology for consideration of product quality within dis...
Foehr, Matthias; Jäger, Tobias; Turrin, Claudio; Petrali, Pierluigi; Pagani, Arnaldo; Leitão, PauloThe present paper deals with the questions how product quality can be influenced within product manufacturing and how production control can be optimized for increasing product quality. It focuses on discrete manufacturing processes and presents a methodology to gather and analyze relevant influences on product quality and a multi-agent architecture for flexible and quality focused production control. It will b...
Adaptation of functional inspection test plan in a production line using a mult...
Rodrigues, Nelson; Leitão, Paulo; Foehr, Matthias; Turrin, Claudio; Pagani, Arnaldo; Decesari, RobertoThe multi-agent systems technology is a proper approach to implement distributed manufacturing systems exhibiting adaptation and flexibility. This paper proposes a multi-agent based solution for the adaptation of the functional test plan in a production line producing washing machines, aiming to increase the process productivity and product quality. The global adaptation mechanism is embedded on the multiagent ...
Methodology for consideration of system quality within manufacturing
Foehr, Matthias; Jäger, Tobias; Turrin, Claudio; Petrali, Pierluigi; Pagani, Arnaldo; Leitão, PauloThe present paper deals with the question how system quality can be influenced within its engineering and manufacturing. It focuses on discrete manufacturing by system of systems and presents a methodology to gather and analyze relevant influences on system quality within a MPFQ-model. The model is based on four main elements: Materials, Processes, Functions and Quality. The paper brings together functional des...
GRACE ontology integrating process and quality control
Leitão, Paulo; Rodrigues, Nelson; Turrin, Claudio; Pagani, Arnaldo; Petrali, PierluigiMulti-agent systems paradigm is a suitable approach to implement distributed manufacturing systems addressing the emergent requirements of flexibility, robustness and responsiveness. In such systems, an ontology is a crucial piece to provide a common understanding on the vocabulary used by the intelligent, distributed agents during the exchange of shared knowledge. This paper describes the design of an ontology...
