A Short Introduction to Digital Twins
Figure 2: Digital Twins bridge the Design and Applications (Yo-i Information Technology) 3
shown in Figure 3 as a vertical expansion that
describes the increase in composition from a
single to many entities.

As the scale and scope of a composite digital
twin increase, it may expand horizontally
from a composite assembly to a more
complex composite system. The coloring in
Figure 3 shows how a composite digital twin
system is made up of multiple composite
digital twin assemblies.
The level of abstraction of a digital twin is
such that it is sufficient for the requirements
of a specific application or use case. A
discrete digital twin is a single entity that
provides value without needing to be broken
down further. Assembling discrete digital
twins to create a composite digital twin is
