Proposed Virtual Architecture by using Multi-Agent Systems

Digital Twins are images from the physical world that when passed to the digital world can be simulated to study behaviors that have not yet been realized. The implementation of a digital Supervisory System in Industry 4.0 requires an active and reactive control in flexible manufacturing systems. In this sense, in this paper an architecture of a Digital Supervisory System is proposed, organized in a multi-agent environment, related to cooperation, coordination and negotiation among the agents. For communication the Publisher/Subscriber communication paradigm with the MQTT (Message Queuing Telemetry Transport) protocol is used for the organization and distribution of data among the devices. The modeling technique used in the architecture is based on PFS (Production Flow Schema) and coloured Petri Net.
