Data collection for global monitoring and trend analysis in the GRACE multi-agent system. In IEEE International Conference on Industrial Technology (ICIT‘13). Cape Town: IEEE. p.1240-1245. ISBN 978-1-4673-4567-5978-1-4673-4567-5http://hdl.handle.net/10198/9102Multi-agent systems (MAS) paradigm is a suitable approach to implement distributed manufacturing systems addressing the emergent requirements of flexibility, robustness and responsiveness. In such systems, the distributed agents have a local view of the system environment being the global data collection a complex and critical issue to provide the functionalities of the ISA-95 standard, such as dynamic scheduling, maintenance management and quality assurance. This paper describes the data collection mechanisms in a multiagent system that supports the global monitoring over the time and the trend analysis to perform self-adaptation and selfoptimization. The proposed approach was developed and tested in an industrial washing machines production line.engMulti-agent systemsData collectionconference object
