30: Activity UpdateDigitalFromPhysical

For now, all that is done here is the assignment of a dummy time stamp. In reality, an entire synchronisation of relevant data and information would occur. Note that this update cycle need not involve only automated "sensors" or initially only «digital» information, although eventually the information must be converted to a «digital» form for writing to the «digital»

@Entity :

Webel Twin Pattern: The sensor/actuator twinning control loop can involve automated devices (SensorDevice and/or ActuatorDevice) and or humans (SensorHuman and/or ActuatorHuman).

This concludes the slides for the acquisition case. Note that some of these Activities are also used for the creation (build, make) case as we'll see next .

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

Notes

[POLICY]{STRICT} Webel Twin Pattern: A PotentialPhysicalAsset is «digital», not «physical». It is used to acquire (an existing) or create (build, manifest, make) an «physical» ActualPhysicalAsset, which is a special case of «physical» PhysicalEntity.

[POLICY]{STRICT} Webel Twin Pattern: A «digital» DigitalEntity (a.k.a. @Entity) encapsulates strictly geometrical, spatial, and material aspects of a «physical» PhysicalEntity only. BY DEFINITION of this pattern it DOES NOT encapsulate processes!

[POLICY] Webel Twin Pattern: Once a PotentialPhysicalAsset has been integrated with a real, existing (has mass) ActualPhysicalAsset under twinning control, its job is done forever (although it may be kept as an historical tracking record).

[POLICY]{STRICT} 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.

[POLICY]{STRICT} Webel Twin Pattern: An ActualPhysicalAsset is an asset that is also a «physical» PhysicalEntity.

[POLICY]{STRICT} Webel Twin Pattern: The sensor/actuator twinning control loop can involve automated devices (SensorDevice and/or ActuatorDevice) and or humans (SensorHuman and/or ActuatorHuman).

Snippets (quotes/extracts)

Traditionally, industry has created digital twins by retrospectively mapping, scanning, surveying, digitising or developing a digital copy of a real world object.
