Digital Twins Taxonomy Draws the Line Between a Model and a Twin
An interactive field guide and classifier for distinguishing simulations, digital models, digital shadows, digital twins, and adaptive twins.
Field notes
The atlas separates coupling from other descriptive dimensions, so a system can be classified by its data relationship before claims about personalization or maturity are considered. Its ladder runs from offline simulation through one-way digital shadow to two-way digital twin and adaptive twin, while the diagnostic uses six signals including representation, counterpart, observation, influence, and identity. Biomedical examples treat clinician-authorized intervention as a possible governed return path.
