Digital twins are virtual replicas of physical assets that allow for monitoring, simulating, and optimizing processes to improve efficiency and make decisions.
Immersive technology has advanced significantly in the last decade, driven by innovations in the Internet of Things (IoT), artificial intelligence (AI), and real-time data analytics. These developments have led to digital twins, digital transformation tools that are redefining sectors within Industry 4.0. By improving operational efficiency, reducing costs, and delivering strategic insights, digital twins provide a complete digital view of processes and assets.
Imagine having a digital replica of your assets that allows you to foresee and solve problems before they even happen. This level of foresight and control is no longer science fiction. Digital twins enable companies to predict outcomes, make data-driven decisions, and continuously optimize critical processes, directly impacting the business economy by reducing maintenance costs and downtime. Industries such as manufacturing, construction, healthcare, and smart cities are adopting this technology as a strategic and, in many cases, indispensable investment.
Definition of the Digital Twin
A digital twin is a virtual replica of a physical object, system, or process that simulates its behavior in real time through data. This technology allows monitoring, analyzing, and improving the performance of the replicated object using accurate simulations and data obtained from the device or system in operation.
In essence, the digital twin is not just a static representation but a dynamic tool that adapts and learns over time, enabling businesses to optimize efficiency and foresee problems before they occur.
To put it into perspective, imagine a manufacturing plant where each machine and each process is monitored through a digital twin. With every new data point, the system predicts failures before they arise, optimizes workflow, and ensures smooth, uninterrupted operations. Digital twins allow companies to act in the present while planning for the future.
Digital Twin vs. Metaverse: Are They the Same?
Although digital twins are often associated with technologies such as virtual reality (VR), augmented reality (AR), and extended reality (XR), their purposes are different.
While VR and AR create immersive environments to simulate or expand reality, the digital twin goes further by replicating real-time behavior and condition of a physical object. This enables companies not only to visualize but also to interact and optimize the operation of their systems in a controlled virtual environment.
Types of Digital Twins: Application Examples
When we talk about "types of digital twins," we are referring to the level of complexity and intended use.
Component Digital Twins
There are virtual representations of one or several individual parts.
They monitor single pieces and allow for predictive maintenance, detecting signs of wear before they cause downtime.
Ideal for large structures with multiple critical components, where anticipating degradation and preventing failures is essential.
For example, a component twin might represent each bearing in a production line, allowing operators to track wear and replace it before it disrupts operations.
Asset Digital Twins
Secondly, asset or product digital twins represent a set of individual parts functioning as a unified whole.
They represent entire machines or systems and are used to optimize performance and lifecycle management.
They help identify and solve issues more efficiently, boosting productivity and lowering maintenance costs.
Following the earlier example, an asset twin could be a complete assembly machine, providing insights into performance issues and enabling configuration adjustments.
System Digital Twins
They represent one or more interconnected assets working as a unified structure.
They analyze how different assets interact to improve coordination and efficiency.
These twins are particularly useful in scenarios where synchronization between components is critical to avoiding bottlenecks.
For example, a digital twin of an entire production line makes it possible to visualize interactions between machines and detect potential bottlenecks before they escalate.
Process Digital Twins
Process twins provide a bird’s-eye view of entire workflows, supporting real-time, data-driven decision-making.
They simulate entire workflows, allowing the optimization of complex processes.
They facilitate real-time decision-making and forecasting of issues in large-scale systems.
For instance, a process twin could replicate the full production workflow, from raw materials to the finished product, allowing for real-time adjustments that minimize waste.
Benefits of Digital Twins in Industry 4.0
Digital twins allow organizations to simulate different scenarios and analyze real-time data with the objective of optimizing processes and making data-based decisions.
Thanks to predictive models, digital twins anticipate problems and facilitate preventive maintenance, reducing interruptions and associated costs.
They also foster innovation by validating new ideas in a controlled environment, lowering risks when implementing changes. Additionally, they optimize the use of resources and help minimize environmental impact, contributing to more sustainable operations that remain adaptable in rapidly changing markets.
Application of Digital Twins
Digital twins are proving their value across numerous industries, from manufacturing to the design of smart cities. Here are some practical applications:
Manufacturing and machine tool: Digital twins enable predictive maintenance and improve operational efficiency. Allows monitoring wear of critical tools in real time, reducing downtime and improving work accuracy. According to McKinsey, their adoption can reduce operational costs by up to 30%.
Construction: In the construction and architecture industry, digital twins optimize building design, prevent costly issues, and improve sustainability through simulations.
Steel Industry: Digital twins can monitor equipment in high-temperature environments, optimizing furnace use and reducing wear on critical parts. They help anticipate failures, reduce maintenance costs, and improve safety at work.
Smart Cities: Digital twins are fundamental in the design of smart cities, allowing real-time monitoring of traffic, energy and water consumption, and other critical urban systems.
Maritime Industry: In shipping, digital twins support vessel monitoring and route simulation, optimizing fuel consumption and improving operational safety.
Energy: Digital twins allow advanced management of energy networks and resources, identifying opportunities for better distribution and reducing equipment wear. They also support maintenance planning, reducing unexpected failures while improving energy efficiency and sustainability.
Best Practices for Implementing a Digital Twin in Your Company
Successfully implementing a digital twin requires clear planning and a modular approach. It is essential to define specific objectives and select complementary technologies such as IoT and AI that maximize the value of the solution.
Integrating the digital twin with existing systems ensures seamless data synchronization and provides a unified operational view. With a strategic approach, businesses can unlock the full potential of this transformative technology.
Real-World Examples of Digital Twins
Digital Twin in the Manufacturing Sector
DIMECO specializes in the manufacturing and supply of automated production lines for metal processing.
In this case, we applied our Digital Twin platform TOKII to create a graphical representation of the HMI of their production lines, as well as to calculate loop and production speed.
Digital Twin in the Maritime Industry
VICINAY MARINE is a leader in the design, innovation, production, and supply of chains and mooring lines for the wind and naval industries.
Their challenge was to integrate and organize over 20 years of data, which had been scattered across different applications and accessed through tools that were neither intuitive nor interactive.
Digital Twin in Construction
TEICON is an engineering and construction company focused on innovation and Industry 4.0.
They use our TOKII digital twin solution for their construction projects to manage maintenance tasks and technical information of all machinery from a single control point.
