A SOA-based architecture for empowering future collaborative cloud-based industrial automation

The last years we are witnessing of rapid advances in the industrial automation domain, mainly driven by business needs towards agility and supported by new disruptive tech- nologies. Future factories will rely on multi-system interactions and collaborative cross-layer management and automation ap- proaches. Such a factory, configured and managed from archi- tectural and behavioural viewpoints, under the service-oriented architecture (SOA) paradigm is virtualized by services exposed by its key components (both HW and SW). One of the main results of this virtualization is that the factory is transformed into a ”cloud of services”, where dynamic resource allocation and interactions take place. This paper presents a view on such architecture, its specification, the main motivation and considerations, as well as the preliminary services it may need to support.Validerad; 2012; 20121016 (jerker
