Introduction
What is the Digital Twin and how can it help us?
What services can be
provided (by whom and to
who) through (or adopting,
or developing) the digital
twin concepts?
Our focus is long-life capital equipment

Apply Service Dominant Logic in the assessment
Consider technical and business hierarchies

Discussion
What is the digital twin and how can it help us?
The Digital Twin supports many actors and provides
advice to help them to make reliable decisions
- System level – component to business ecosystem
- Lifecycle phase – BOL, MOL, EOL
- Management level – operational, tactical, strategic
- Timeframes – live, daily, weekly, monthly, annually
The Digital Twins role is to provide decision making advice or support

Closing
Conclusions
The Digital Twin is currently
‘all things things to all
people’
It’s main role is to support
better decision making
The Digital Twin is a representation of a machine or a business
Simulation approaches depend on the questions being asked
The Digital Twin should contain the current and past states
A family of Digital Twins are required rather than a single twin

Closing
Recommendations
How to innovate Smart
Services based on a family of
Digital Twins (some of whom
may not want to talk to each
other) that can provide solid
decision making advice
Learn to design, build and test Digital Twins
Learn to build families of Digital Twins
Learn to connect the different dimensions and layers
Learn to understand the fundamental data and information
