The Internet of Things (IoT), machine learning, and other forms of industrial AI are converging and being leveraged to effectively collect, analyze and take action upon production line data. Nowhere is this truer than in industrial digital twin use cases that are driving tangible ROI for the business.


Digital twin use cases and examples

Digital twin technology has actually been around for some time. NASA developed an early digital twin to simulate conditions on Apollo 13, and today utilizes a digital twin to monitor the entire Space Center.

While manufacturing can’t boast digital twin examples as dramatic as rescuing stranded astronauts, applying digital twin technology to both products and the manufacturing process itself is solving painful business problems and yielding quantifiable improvements for the industrial sector.


What is a Digital Twin?

By 2021, half of large industrial companies will use digital twins.

     – Gartner

A digital twin is a virtual representation of a physical system that simultaneously stands as an entity on its own. This digital copy is a ‘twin’ of information embedded in the physical system, as much as the physical parts.

With the advent of IoT, a digital twin can collect data continuously from sensors and mutually pass information with the physical counterpart throughout the system’s life-cycle.  Everything from manufacturing processes to sensor input, to external management software can be fed into, and organized inside, the digital twin.

Digital twins aggregate data, making it easy to identify patterns in historical events, spot root causes, and optimize line processes.


This capacity for aggregating data from and around a physical product or system, as well as functioning as a digital stand-in, opens the way for a broad range of digital twin use cases.

Digital Twin Use Cases: Production Processes and Product Performance

Imagine the following example:

A chemical manufacturing plant produces half a billion dollars worth of finished goods a year. Each line contains highly specialized and expensive machines, along with carefully detailed ‘recipes’ of raw materials and machine settings used to produce the end product.

Now imagine a digital copy of the production lines in the factory, including sensor data collected from production line machines (typically stored in a data historian); ERP data of the raw materials, production orders, and recipes; and quality management system data, among others.

The manufacturer needs to continually optimize production yield by reducing unplanned machine downtime, reducing the amount of ‘scrap’ produced in each production run, and minimizing costly production quality faults.

Normally, process engineers collect and analyze mountains of data, slowly narrowing down which information can help them. Only after an exhaustive research would they – perhaps – start noticing correlations that can help them optimize this complex system of assets and instructions.

Now add the Digital Twin:

Effective digital twin software will ingest data from relevant IT and OT sources and display it on a virtual copy of the plant line. Process engineers, QA teams and others can understand the data in the context of the machines, the raw materials, and the entire production line environment.

If the digital twin system is coupled with root cause analysis tools, it will even point out which variables need urgent attention, speeding up root cause investigations and optimization processes.

Monitoring production line and individual machine health

Digital twins are first and foremost the EKG monitors of manufacturing – they visualize and track your production line’s pulse.

Skilled operators can notice something wrong with a machine just by touching its surface or listening to its vibrations. The digital twin takes that intuition a step further by showing how the problem is reflected through data, helping investigation teams identify problems in assets more quickly and even mitigate the same problem in the future.

In addition, all of this insight is available remotely. Engineers can troubleshoot equipment remotely via the digital twin, reducing incident resolution times more quickly and accurately than through viewing the data on historians, MES or quality management software alone.

Why? Because of the importance of context.

Using digital twins to understand data in context

Production line data is stored in different systems: some data is saved in data historians, some in ERP, MES and quality systems; some is stored manually, and some is processed automatically.

When data isn’t aggregated and organized in a digestible way, it’s useless for reaching accurate and actionable insights.

Take the example of a production line which yields 10,000 bricks per batch, with 1.5% scrap at the end of the process. Over time, each batch produces more waste and smaller yields.

To identify the source of the issue, an engineer first needs to pinpoint the step of the process where they are losing throughput by monitoring machine downtime.

But reviewing downtime data from different sources is time-consuming and makes it difficult to spot correlating indicators. A digital twin gives a more integrated view of environmental factors, individual machines, and how they interact to affect the operational quality and asset performance.

That engineer, viewing downtime on a digital twin, can quickly and accurately pinpoint the root cause of the problem (e.g. low temperature in an oven) and the chain of events that lead to scrap.

Digital Twin Use Cases for OEMs: Control and Visibility

A digital twin of individual assets – for example, a packaging machine – drives business benefits that span the entire product life cycle:

  • Product Development – Engineers, designers, and developers create digital prototypes, then run simulations to test the product’s usability. OEMs can cut development and production costs by reducing bugs before the product hits the shelf.
  • Setup via digital twin: Products can be activated from remote service centers, reducing service costs for consumers.
  • Post-production troubleshooting  – When all data about a live product’s behavior is captured in a digital twin, it’s easy for engineers to troubleshoot reported errors in the product.

The Future of Digital Twins

Digital Twin use cases are as varied as manufacturers are innovative. As AI technologies advance, digital twins will be adapted to deliver even more exciting applications for industrial manufacturing.
