SysML Block Definition Diagram (BDD)

Webel Twin Pattern: DigitalTwin: The multiplicity of 'digitalEntity:@Entity' and 'physicalEntity:PhysicalEntity' MUST be [1] when the DigitalTwin is in the state Attached, the @Entity is in the state Bound, and the PhysicalEntity is in the state Exists.

31: Case: Create a new physical asset using a «digital» @Entity initially as a digital "template"

SysML Activity Diagram

Webel Twin Pattern: An ActualPhysicalAsset is an asset that is also a «physical» PhysicalEntity.

Webel Twin Pattern: A DigitalTwin and PhysicalEntity must both be 'attached' to Sensors and/or Actuators under management of the DigitalTwin before the twinning control loop is fully entered.

Webel Twin Pattern: Not every twinnable PhysicalEntity is worth treating as an asset.

Webel Twin Pattern: A DigitalTwin (even a "process twin" or "finance twin"), always, without exception, BY DEFINITION HERE either directly or indirectly involves at least one existing or anticipated PhysicalEntity (even if only via another DigitalTwin)!

Webel Twin Pattern: A DigitalEntity (a.k.a. «digital» @Entity) used as a digital variant must not be directly bound to a «physical» PhysicalEntity (may not directly actuate/sense/affect)

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.
