Large industrial companies set to embrace digital twins by 2021, says Bentley Systems

Keith Bentley 11 AUgAs digital twins advance beyond BIM and GIS, more than half of all large industrial companies expected to use digital twins in some form by 2021, according to Keith Bentley, founder and chief technology officer, Bentley Systems

What is a digital twin?

The term “digital twin” is commonly used now, and infrastructure professionals are beginning to intuitively understand what a digital twin is and what it does. Bentley did not invent the term or concept of a digital twin. In fact, the term did not even originate from the infrastructure industry. I believe that the concept of digital twin is quite simple. If you have a physical asset and a digital asset that would represent everything in the physical asset, you could join them together, using the digital one for understanding what is happening with the physical asset in the real world.

The one problem, however, is that assets change all the time. Even with a large-scale infrastructure asset, while the entire asset probably does not change all that much, some part of the asset changes every day.

A digital twin must connect from the physical world to the digital world. If you have a digital twin and it does not reflect the current state in the real world, not only is it not going to be valuable, but it could be dangerous. This connection also means that the reverse can be true: the digital world needs to connect to the physical world, allowing you to change the digital representation in preparation for changes that you plan to make to the physical asset.

When thinking about how things change over time, a digital twin is about marrying the two worlds and keeping them in sync. That idea makes a digital twin different from what has been talked about before. While digital twins must have that dimension of time, they must also have context. If you have sensors out in the real world that are telling you what is happening, you should be able to visualise that data with your digital twin. Things like reality capture, such as what Bentley’s ContextCapture provides, should be a part of the digital twin

Value of a digital twin

The value of a digital twin will grow and multiply when connections are formed. The more of them that are formed, the greater the value is. Digital twins provide opportunities, such as opportunities to improve the processes that exist today. They can help you with costs, safety, resilience, and even your carbon footprint. 

However, digital twins provide not only the opportunity to change the design process, but to also change the business process. If industry professionals can improve their metrics—such as cost efficiency and safety—they are creating value. If that added value can be ascribed to the person who made it possible, the industry has a selfish motive: improving the bottom line for the asset’s entire lifecycle.

Digital twin offers flexibility

While no one knows what a digital twin is going to be five years from now, it will certainly be connected to more systems than are possible today. The industry wants the flexibility to change as requirements change and as things become possible that were not before. In software terms, and what we at Bentley believe, that means being open. 

Infrastructure professionals want the flexibility to be able to take data and combine it with other data sources, send it to other systems, or give it to another vendor to have them write some software. While that does not mean that you should start becoming programmers, you should have the flexibility to do that if you choose.

What’s next?

Not everything is going to be perfect. It is not all going to work the first time. With software development, you need to be agile and work within the cycle of build, measure, learn. For Bentley, this cycle is ongoing and repeats every three weeks. Even if you build something, you run it, you test it, and you see whether your hypothesis is being satisfied. If it is not, you adjust. That cycle repeats so quickly, allowing you to react to whatever works and stop doing whatever does not work.
