摘要

The digital twins (DTs) concept offers a promising approach for digitally representing their physical counterparts, referred to as physical twins (PTs). Throughout the PT life cycle, DTs are paired via feedback loops, enabling continuous data circulation that provides unique opportunities beyond traditional simulations. However, we can observe the lack of a systematic, methodological approach to the design and development of DTs. Consequently, we ran a qualitative visual research study with 19 industry and academic experts to aggregate and merge the current approaches to designing DTs. Our results suggest that the DT design is a non-finite process that evolves in parallel with the PT. The expert study also allowed us to identify 17 key components of the DT design process, including 4 unique and crucial elements that were only mentioned by a handful of experts. We also contrasted the resulting DT design method with a range of well-established design methodologies. The result of the latter process suggests that an appropriately modified and amended Waterfall design method can serve as a high-level approach to DT design.
