The GO0DMAN Cyber-Physical System (CPS) architecture integrates production and quality control, in multi-stage production lines, towards the improvement of product quality and addressing the requirements of zero-defects manufacturing (ZDM). For this purpose, the system architecture will use a distributed and decentralized approach based on Multi-Agent Systems (MAS) principles.
MASThe MAS will comprise a society of distributed, autonomous and cooperative intelligent agents representing the production components disposed along the multi-stage production system, in some cases having a direct association to a physical resource, e.g. a welding robot, a quality control station or a sensor, but in other cases representing logical entities, such as data analytics and self-learning tools. Even the products being produced along the line will have associated an intelligent agent, which transforms a passive product into an intelligent product, with capabilities to gather and store data from its historical production process and the current operation data from its in-house sensors, supporting the reasoning for real-time decision-making.

Each stage and resource disposed along the line has associated an intelligent agent, forming a multi-agent system, which collects, stores and processes data in a distributed manner. This on-line gathered data will be enriched with pre-analytical algorithms enabling the rapid reaction to critical situations, and particularly the earlier identification of anomalies, deviations and patterns leading to condition changes or defects, and the application of proper mitigation strategies for self-adaptation and optimization according to several criteria. These agents are able to interact among each other according to some coordination patterns aiming to share their knowledge and capabilities, and consequently capable to implement inter-stage coordination policies towards the ZDM strategies. Particularly, the integration of process and quality control aiming at the implementation of feedback control loops for preventing the occurrence and/or propagation of defects is achieved by the interaction among these types of agents.
