Author(s)
Deogratias Kibira, Guodong Shao
The applications of digital twins continue to grow with the volume and variety of data collected. These data support the modeling of function, behavior, and structure of a physical element. However, successfully building a digital twin requires data

A Human-centered Framework to Update Digital Twins

July 13, 2023
Author(s)
Peter O. Denno, Deogratias Kibira
Developing a digital twin (DT) involves establishing (1) a predictive capability (a model) relevant to the application, (2) means to collect data from the physical counterpart, and (3) means to apply the collected data to the model. Ideally, with these
