abstract
- The Digital Twin approach has emerged in the Industry 4.0 context to perform the design, virtual commissioning and optimization of processes and machines, considering the simulation model feed with real-time data, and articulated with AI data-driven algorithms to extract value and knowledge. The digital Twin can be seen as a way to proceed with the digitalization of production assets, covering the layers dimension defined by the RAMI 4.0 model. However, a pertinent question is related to understand the relationship between the Digital Twin concept and the other two dimensions of the RAMI 4.0 model, and particularly the way to address the distributed nature exhibited by the hierarchy levels and the life-cycle management defined by the life-cycle value stream dimension. Having this in mind, this paper aims to analyse the coverage of the Digital Twin concept according to the three dimensions of the RAMI 4.0 model, particularly considering the inherent capabilities of Multi-agent Systems to support the development of more distributed and pro-active Digital Twin ecosystems that cover the life-cycle management, facing the demands established by Industry 4.0 compliant solutions.
