What is Digital Twin?
A digital twin is a digital representation 
of a physical object, process or service. 
A digital twin can be a digital replica of 
an object in the physical world, such as 
a jet engine or wind farms, or even 
larger items such as buildings or even 
whole cities.

Replicate processes
The digital twin technology can be used 
to replicate processes in order to collect 
data to predict how they will perform.

How it perform?
A digital twin is, in essence, a computer 
program that uses real world data to 
create simulations that can predict how 
a product or process will perform. 
These programs can integrate the 
internet of things (Industry 4.0), artificial 
intelligence and software analytics to 
enhance the output.

Machine learning
With the advancement of machine 
learning and factors such as big data, 
these virtual models have become a 
staple in modern engineering to drive 
innovation and improve performance.

Strategic technology 
trends
In short, creating one can allow the 
enhancement of strategic technology 
trends, prevent costly failures in physical 
objects and also, by using advanced 
analytical, monitoring and predictive 
capabilities, test processes and services.

How does a digital 
twin work?
A digital twin begins its life being built 
by specialists, often experts in data 
science or applied mathematics. 
These developers research the physics 
that underlie the physical object or 
system being mimicked and use that 
data to develop a mathematical model 
that simulates the real-world original in 
digital space.

How does a digital 
twin work cont.
The twin is constructed so that it can 
receive input from sensors gathering 
data from a real-world counterpart. This 
allows the twin to simulate the physical 
object in real time, in the process 
offering insights into performance and 
potential problems.

Physical counterpart
The twin could also be designed based 
on a prototype of its physical 
counterpart, in which case the twin can 
provide feedback as the product is 
refined; a twin could even serve as a 
prototype itself before any physical 
version is built.

Digital twin vs. 
simulation
The terms simulation and digital twin are 
often used interchangeably, but they are 
different things. 
A simulation is designed with a CAD 
system or similar platform, and can be 
put through its simulated paces, but 
may not have a one-to-one analog with 
a real physical object.

Digital-twin use 
cases
The digital-twin examples we highlighted 
above – the car and the cargo vessel – 
provide a sense of potential use cases. 
Objects such as aircraft engines, trains, 
offshore oil platforms, and turbines can 
be designed and tested digitally before 
being physically produced.
