Immersive technology is advancing at a rapid pace, driven by innovations in the Internet of Things (IoT), Artificial Intelligence (AI), and real-time data analytics. This convergence has given rise to digital twins, one of the most transformative tools of the digital era.

Digital twins have become fundamental pillars of digital transformation within Industry 4.0. Their ability to create accurate virtual replicas enables organizations to improve operational efficiency, reduce costs, and gain valuable strategic insights through a comprehensive digital view of their physical processes and assets.

Today, multiple industries are adopting this technology as a strategic investment to boost efficiency, advance sustainability, and strengthen their competitive position in the market.

The origin of the “digital twin” and its historical evolution

Although the modern term “digital twin” gained popularity in recent decades, its essence dates back to space exploration, with NASA being a pioneer in applying similar concepts during the Apollo 13 mission in 1970.

After the explosion of one of the spacecraft’s oxygen tanks, NASA engineers used ground simulators and exact replicas of the vehicle to virtually recreate the conditions of the damaged spacecraft. This allowed them to analyze the cause of the failure and develop and validate real-time solutions, which proved crucial to ensuring the astronauts’ safe return. This intervention is widely recognized as the first practical application of what we now call a digital twin.

Decades later, in 2002, Michael Grieves formalized the theoretical concept within the context of Product Lifecycle Management (PLM) during a presentation at the University of Michigan. Later, in 2010, John Vickers of NASA officially coined the term digital twin to describe, more concretely and operationally, this dynamic connection between the physical world and its virtual replica, continuously fed with real-time data.

Definition of a Digital Twin

A digital twin is a virtual replica of a physical object, system, or process that simulates its behavior in real time using data. This technology enables monitoring, visual analytics, and performance optimization of the replicated element through accurate simulations and data gathered from the real system in operation.

In essence, a digital twin is not a static representation, but a dynamic tool that adapts and learns over time, enabling companies to anticipate failures, explore improvements, and iteratively adjust operations. Imagine a manufacturing plant where every machine and process is monitored through its digital twin: with each new data input, the system can predict anomalies, adjust parameters, and maintain uninterrupted workflow continuity.

Digital twins empower companies to act in the present while planning for the future.

As SAP Signavio points out, digital twins provide organizations with the visibility and understanding needed to plan, test ideas, prioritize initiatives, forecast risks, and manage complexity. In doing so, they help reduce uncertainty in strategy execution and support better-informed decision-making.

Types of Digital Twins: Application Examples

When we talk about “types of digital twins”, we refer to different categories used to organize them by scale, level of detail, and scope of application. These classifications have been shaped by common user needs and help determine what level of digital twin is best for each project. Typically, three main types are distinguished:

Types of digital twins, examples of asset twin, process twin and system twin for industry

Product/Asset Digital Twin

A product digital twin represents an individual physical asset or a family of products, incorporating its geometry, structure, and physical properties, as well as its behavior over time. This type of twin makes it possible to analyze how the asset responds under different operating conditions and anticipate phenomena such as wear, failures, or degradation.

Process Digital Twin

A process digital twin models the sequence of operations that make up a production system, going beyond a single asset. It focuses on how the different stages of the process interact (cycle times, dependencies, variability, or bottlenecks) in order to analyze overall performance. This enables the simulation of scenarios, the evaluation of operational changes, and the optimization of the process as a whole.

System Digital Twins

A system digital twin integrates multiple interconnected assets and processes, such as a complete production line, a plant, or an infrastructure network. Its objective is to analyze how the different elements of the system interact and how changes in one component affect the overall behavior.

Benefits of Digital Twins in Industry 4.0

Digital twins have proven to be a key enabler of industrial digital transformation, delivering benefits that impact both operational efficiency and business strategy:

Improved operational efficiency: By virtually representing assets and processes together with their operational context in 3D, digital twins make it easier to understand how the entire operation functions. This helps identify bottlenecks, optimize operating parameters, and reduce efficiency losses in production.

  • Failure anticipation and predictive maintenance: By collecting and storing operational data in both real time and historical records, these virtual replicas create an operational information base on which different predictive models can be applied. This makes it possible to detect early signals of degradation, anticipate potential failures, and plan maintenance interventions further in advance.

  • Scenario simulation and change validation: One of the most valuable capabilities is the possibility of simulating scenarios before applying them in real operations. This allows teams to evaluate operational changes, test new configurations, or analyze different scenarios without interrupting production or assuming unnecessary risks.

  • Improved quality and waste reduction: By analyzing process behavior in context, digital twins help detect deviations before they turn into defects. This contributes to improving the stability of the production process, reducing scrap, and optimizing the use of raw materials and resources.

  • Greater analytical capability and decision-making: By combining operational data, historical information, and system context in a single environment, digital twins make it easier to understand how the system behaves over time. This helps identify trends, evaluate the economic impact of different decisions, and prioritize improvements or investments on a stronger analytical basis.

Applications of Digital Twins

Digital twins have demonstrated value across multiple sectors, from manufacturing to the design of smart cities. Below are some examples of how this technology is transforming industries:

  • Digital twins in Manufacturing: Enable the simulation and optimization of production lines, helping identify bottlenecks and maximize productivity. They support predictive maintenance by anticipating failures and reducing downtime. According to McKinsey, some factories have reduced operating costs by 5–7% by optimizing planning and eliminating bottlenecks with digital twins.

  • Digital twins in AECO: Optimize building design using AR, improve planning, efficiency, and on-site safety. They allow BIM/CAD data to be visualized in situ and even enable infrastructure layers to be displayed separately for better understanding. Once construction is complete, the twin continues to monitor and support predictive maintenance, becoming, as Innowise defines it, “the brain of the building’s entire lifecycle.”

  • Digital twins in Smart Cities: Urban digital replicas help cities manage key systems such as mobility, utilities, energy and water consumption, and waste management. As PwC highlights, in urban contexts, digital twins continuously capture information about the built environment via sensors and drones, ensuring constantly updated representations.

  • Digital twins in Energy: Allow for the virtual replication of entire energy infrastructures, from generation plants (wind, solar, offshore) to distribution networks. This enables advanced, real-time management of assets and resources, identifying improvement areas in distribution and reducing energy losses.

  • Digital twins in Education: Enable gamification of tasks into challenges and achievements, making learning more dynamic and motivating. They allow students to practice skills in safe, controlled environments and provide detailed progress tracking for more personalized education.

  • Digital twins in Telecommunications: Facilitate visual monitoring of antennas, towers, nodes, and distributed data centers. They provide real-time, detailed information about asset status, allowing for rapid detection of failures or anomalies through graphical interfaces and 3D models.

FAQs – Everything You Need to Know About Digital Twins

  • Are digital twins just 3D models?

Not necessarily. While they often include visual representations or 3D models, their real value lies in the ability to replicate the dynamic behavior of the asset. What makes a digital twin powerful is the intelligent layer: real-time data connectivity, data analysis, predictive insights, and process optimization.

  • Are digital twins only for large companies?

No. While large enterprises may gain more advantages due to bigger budgets, digital twins also create significant value for small and medium-sized businesses. They are especially useful for organizations without dedicated data analytics teams who prefer to manage information internally.

The main advantage is that they are scalable: companies can start with a single asset, machine, or process, and expand progressively to entire plants or multiple projects.

See our success stories for examples of SMEs already using digital twins for predictive maintenance and operational optimization, achieving tangible benefits from early stages.

  • Are digital twins difficult to use?

It depends on the solution. Our digital twin platform, TOKII, for example, has been designed to be as intuitive as possible, even for non-technical users. The interface is user-friendly, 3D environments and KPIs can be configured with simple clicks, and AI-powered predictions are completely no-code, no programming required.

  • What infrastructure is needed to implement digital twins?

Ideally, you need sensors and smart devices to feed the system in real time, the more complete the sensor layer, the more accurate the replica will be. Historical data is also highly valuable, as it can train predictive models and improve simulation reliability.

In cases where sufficient data is unavailable, it is possible to generate simulated scenarios as a starting point, which can then be refined with real data over time.

  • What are the disadvantages of digital twins?

The main drawback is the initial investment required. The cost of a digital twin depends on multiple factors. For very sophisticated projects, the investment can be high, but when aligned with a clear business need, it translates into savings, efficiency, and an ROI that outweighs the initial cost.
