abstract="Digital Models/Shadows/Twins/...have been given numerous definitions and descriptions in the literature. There is no consensus on terminology, nor a comprehensive description of workflows nor architectures. In this paper, we use the catch-all ``Digital T'' (pronounced ``Digital Twinning'') to refer to all concepts, techniques, architectures, ...related to the ``twinning'' paradigm. In this paradigm, virtual instances, known as twins, of a System under Study (SuS) are continually updated with the SuS's health, performance, and maintenance status, over its entire life-cycle. Digital T can be used for monitoring, analysis, optimization, and adaptation of complex engineered systems, in particular after these systems have been deployed. Digital T makes full use of both historical knowledge and of streaming data from sensors. Following Multi-Paradigm Modelling (MPM) principles, this paper proposes to explicitly model construction/use workflows as well as architectures and deployment of Digital T. Applying product family modelling allows for the de-/re-construction of the different Digital T variants in a principled, reproducible and partially automatable manner. Two small illustrative cases are discussed: a Line-Following Robot and an Incubator. These are representative for respectively an Automated Guided Vehicle and an Industrial Convection Oven, both important in an industrial context.",
