Digital Twin NEWS! -ISO-IEC-JTC1-SC41-IoT has launched its Digital Twin framework standardisation at its Nov. Plenary. -Edge Computing & Networking, from VLSI to AI and back, in real time when needed, is essential in this endeavour, with specifications from ETSI (ETSI-ISG-MEC: Multi-Access Edge Computing), 3GPP and One M2M supporting this goal. Cyberphysical systems benefit highly of Digital Twins for optimised fault-tolerant operation, verification and validation, simulation, in particular. -Combining functionalities tightly is a must: software, efficient/secure and sustainable data handling, computing and networking may have to be jointly managed, and possibly integrated at every node of a system using fully Digital Twins.
Speed and energy efficiency are available from VLSI chips integrating two functional layers as the IMX500 from Sony: -Data layer: interfacing to the real world (analogue to digital sampling, and digital to analogue rendering, "data I/O" layer)
-Processing layer ("logic" layer) e.g. with AI algorithms to build or prepare decisions from the data acquired, and conversely to manage and implement decisions into the physical world.
Use cases include smart city functionalities, cognitive design/manufacturing, autonomous systems/vehicles.
What is your view on Digital Twin, in what role is it best positioned? Design? Operation? Fault correction? Other?

Many thanks for all valuable contributions. Could I ask for adding software strategies in digital twins? Human usability (as VR/AR...)? Real time aspects? Complexity versus understandability and therefore level of detail in Digital Twin representation of Physical Original? Cyberphysical aspects?
I agree with Mustafa Aljumaily for adding digital twins use for different fields link
Also i agree with Renaud Di Francisco for adding link in soft ware srategies in digital twins
Dear Renaud Di Francesco,
I would like to recommend this article about "Digital Twin in the IoT":
Roberto Minerva, Gyu Myoung Lee, Noel Crespi: „Digital Twin in the IoT Context: A Survey on Technical Features, Scenarios, and Architectural Models“; Proceedings of the IEEE, June 2020, DOI: 10.1109/JPROC.2020.2998530

This article is very professionally written, very informative, and has a long reading list.
Best regards

Digital Twin is a software analogue of a physical device that simulates internal processes, technical characteristics and behavior of a real object under the influence of interference and the environment.
The digital twin is used at all stages of the product life cycle, including development, manufacturing and operation. Already at the stage of preliminary design using software for system / simulation modeling, it is possible to create variations of the system model of the product being developed to evaluate and select the best technical solution. Further, at the technical design stage, the model obtained at the previous stage can be refined and refined using more accurate system models of elements, which can be obtained on the basis of the results of multivariate numerical calculations converted into a reduced order model - ROM-model. This multiphysics accurate system model allows to take into account and optimize the interaction of all elements, taking into account operating modes and environmental influences.
Ansys, Inc. offers its original concept of the Digital Twin based on the comprehensive use of numerical modeling technologies. Leading companies have used numerical simulation in the past to create virtual prototypes of complex technical devices and systems containing mechanical, electronic, and embedded software components, as well as to create simplified reduced-order models embedded in algorithms designed to control the operation of a wide variety of industrial equipment. But today the Internet of Things allows information from sensors connected to the device to be transmitted to the Digital Twin as boundary conditions in near real time.
