BY DEFINITION of this pattern it DOES NOT encapsulate processes! [POLICY]{STRICT} Webel Twin Pattern: It is a DigitalEntity (a.k.a. @Entity) - not the DigitalTwin that owns it - that directly «replicates» geometrical, spatial, and material aspects (only) of a single PhysicalEntity. [CONVENTION]{SUBJECT-TO-CHANGE} Webel: Convention: [MIGHT CHANGE]: An '@' prefix in a DigitalTwin model indicates a «digital» Block that maps a non-digital «mappable» Block. Related notes (backlinks) [ASSERTION]{STRONG} Webel Twin Pattern: Not every twinnable PhysicalEntity is worth treating as an asset. [POLICY]{STRICT} Webel Twin Pattern: A DigitalTwin may use one or more variantEntity:@Entity[0..*] to explore the impact of changes (optimisation studies, trade off studies) and then use them to drive the PhysicalEntity into a desired state (via its ControlSystem). Related snippets (extracts) Digital twins are dynamic, data driven, multi-dimensional digital replicas of a physical entity. They encompass potential or actual physical assets, processes, people, places, systems, devices and the natural environment. In contrast to traditional digital models, digital twins can connect with the physical ‘twin’ they model, changing alongside the physical system via real-time sensors and actuators.
