DIGITAL TWIN IN THE FACTORY: A REALITY MADE POSSIBLE

By using digital twin technology, manufacturers can monitor, simulate, and optimize the performance of their assets in real-time, as well as test new scenarios and solutions before implementing them in the real world - By K.A. Gerardino.

DIGITAL TWIN IN THE FACTORY: A REALITY MADE POSSIBLE

Imagine a factory where you can monitor and control every aspect of the production process, from the machines' design and performance to the product's quality and efficiency. How about a factory where you can test and optimize different scenarios, such as changing the layout, adding new equipment, or adjusting the parameters, without affecting the actual operations? Now, try and visualize a factory where you can detect and prevent problems before they cause downtime, waste, or defects. This is not a fantasy, but a reality made possible by digital twin technology.

Digital twin in a factory is a concept that involves creating a virtual representation of a physical asset, such as a machine, a process, or a building, using data from sensors or other sources. By using digital twin technology, manufacturers can monitor, simulate, and optimize the performance of their assets in real-time, as well as test new scenarios and solutions before implementing them in the real world. Digital twins in factories can help improve efficiency, quality, safety, and innovation in manufacturing systems. In this paper, we will explore the benefits and challenges of the digital twin in factories and some real examples of how it is applied in different industries.

Before we begin, let us go back to history when the digital twin concept first started. According to some sources, the idea of digital twin technology was first voiced in 1991, with the publication of Mirror Worlds, by David Gelernter. However, Dr. Michael Grieves (then on faculty at the University of Michigan) is credited with first applying the concept of digital twins to manufacturing in 2002 and formally announcing the digital twin software concept. He proposed the digital twin as the conceptual model underlying product lifecycle management (PLM). The term “digital twin” was later popularized by John Vickers of NASA in a 2010 Roadmap Report. NASA used digital twin technology to simulate systems in space, such as the Apollo 13 mission in 19703. Since then, digital twin technology has evolved and expanded to various domains and industries, thanks to the advancement of sensors, the Internet of Things (IoT), cloud computing, and artificial intelligence (AI).

Digital Twin in your Factory
Digital twin technology is a powerful tool that can help you improve your factory’s performance, efficiency, and innovation. By creating a virtual replica of your physical assets and systems, you can monitor and control them in real-time, test and optimize different scenarios, and predict and prevent problems. But how can you implement digital twin technology in your factory? What are the steps and benefits of using this technology?

First, you need to acquire data from your physical assets and systems using sensors, operational data, maintenance history, and other sources. This data should be accurate, reliable, and consistent to reflect the current state and condition of your assets.

Second, you need to develop a digital twin by integrating this data into a virtual model of your asset using a digital twin solution. The digital twin should be able to simulate the behaviour and performance of your asset under different scenarios and conditions. You can use various tools and platforms to create and manage your digital twins, such as Resonai, Facilio, or Hitachi Lumada.

Third, you need to boost the capabilities of your digital twin by adding more data layers and analytics to support new use cases. You can use artificial intelligence and advanced modelling techniques to enable your digital twin to provide predictions, prescriptions, and optimizations for your asset. You can also connect your digital twin with other digital twins to create a network of interconnected assets and systems.

Fourth, you need to monitor and control your digital twin by using dashboards, visualizations, and alerts. You can use your digital twin to track the performance and health of your asset, detect and prevent problems, test, and optimize solutions, and implement changes in real-time. You can also use your digital twin to learn from the past, understand the present, and anticipate the future.

Difficulties in Applying Digital Twin Technology
The digital twin is a powerful technology that can create a virtual copy of a real-world component in the manufacturing process. By using inputs from sensors, data analytics, and simulation, the digital twin can help optimize performance, reduce costs, and improve quality. However, implementing and maintaining a digital twin is not without challenges.

Data quality and availability: A digital twin requires a large amount of data from various sources, such as sensors, machines, products, and processes, to create an accurate and realistic model of the factory. However, data quality and availability may vary depending on the factory’s infrastructure, connectivity, and security. Poor data quality and availability can affect the reliability and validity of the digital twin and its simulations.

Data processing and storage: The digital twin also requires a high level of data processing and storage capacity to handle the complex and dynamic data streams from the factory. This may pose a challenge for some factories that lack the necessary hardware, software, and network resources to support the digital twin. Moreover, data processing and storage may incur additional costs and energy consumption for the factory.

Data privacy and security: Digital twin technology involves collecting and sharing sensitive data from the factory, such as intellectual property, trade secrets, and personal information. This may raise concerns about data privacy and security, especially when the data is transmitted over the internet or stored in the cloud. Data breaches, cyberattacks, or unauthorized access may compromise the confidentiality, integrity, and availability of the data and the digital twin. Therefore, digital twin requires robust data protection mechanisms and policies to ensure data privacy and security.

Interoperability and standardization: Digital twin requires interoperability and standardization among different data sources, formats, protocols, platforms, and systems to enable seamless data exchange and integration. However, interoperability and standardization may be challenging due to the diversity and complexity of the factory’s components and processes. Moreover, there may be a lack of common definitions, frameworks, methodologies, and metrics for developing and validating digital twins across different industries and domains. Therefore, the digital twin requires harmonization and coordination among different stakeholders and organizations to ensure interoperability and standardization.

Skills and expertise: A digital twin requires skills and expertise in various fields, such as engineering, computer science, mathematics, statistics, artificial intelligence, machine learning, data science, and domain knowledge. However, skills and expertise may be scarce or unevenly distributed among the factory’s workforce. Moreover, digital twins may require continuous learning and training to keep up with the rapid changes and innovations in technology. Therefore, the digital twin requires investment in human capital development and education to ensure skills and expertise.

Examples of Companies Using Digital Twin
Digital twin technology is widely used in various industries, such as manufacturing, aerospace, healthcare, and energy. Here are some examples of real-life scenarios in the factories using digital twin technology:
