Comparison

Digital twin (DT) can be considered as ‘‘a digital informational construct of a physical system as an entity on its own.” [Grieves, Vickers, 2016] ‘‘Twin” here implies that this digital informational construct would be linked to the physical system throughout its entire lifecycle. The concept of DT intersects with traditional modeling and simulation. Different researches focus on different perspectives of DT in order to highlight the innovative nature of this concept. [Shao and Helu, 2020] summarized some of these perspectives based on the proposed definition, relevant viewpoint (i.e., product, process, or system), fidelity of the digital representation (i.e., complete or partial representation), and temporal integration (e.g., real-time or offline) of a digital twin. This analysis is represented in the current comparison.
