About Digital Twins, agents, and multiagent systems: a cross-fertilisation journey

Digital Twins (DTs) are rapidly emerging as a fundamental brick of engineering cyber-physical systems, but their notion is still mostly bound to specific business domains (e.g. manufacturing), goals (e.g. product design), or application domains (e.g. the Internet of Things). As such, their value as general purpose engineering abstractions is yet to be fully revealed. In this paper, we relate DTs with agents and multiagent systems, as the latter are arguably the most rich abstractions available for the engineering of complex socio-technical and cyber-physical systems, and the former could both fill in some gaps in agent-oriented engineering and benefit from an agent-oriented interpretation -- in a cross-fertilisation journey.Comment: Digital Twin, Agent, Multiagent system, Cyber-physical system;16 pages; accepted and presented at EMAS2022 (workshop of AAMAS: https://emas.in.tu-clausthal.de/2022/#accepted
