Background
Digital twins have emerged as virtual representations of physical objects, systems, or processes, embodying real-time data, advanced modeling techniques, and simulations to mirror their real-world counterparts. This technology found its roots in NASA's critical mission, the Apollo 13 mission, where NASA harnessed high-fidelity simulators controlled by digital computers. These simulators served as virtual replicas of the spacecraft, enabling rigorous testing of failure scenarios and refining critical instructions.
Over time, digital twins have evolved to encompass complex models that bridge the gap between physical and digital realms, enabling enhanced insights and predictive capabilities across industries. They enable researchers and engineers to simulate, analyze, and optimize the performance of physical assets in a virtual environment. It has gained traction in industries such as aerospace, mechanical engineering, civil engineering, chemical synthesis, sustainability, and agriculture.
About the Research
In the present paper, the authors comprehensively explore the digital twin technique. They focus mainly on the methods, protocols, and tools used to develop and deploy these technologies. The study also addresses the limitations and challenges associated with digital twins.
One key challenge was the need for accurate models that remained manageable in complexity. Digital twins are complex systems that require precise modeling to accurately represent their physical counterparts. However, managing the complexity of these models is a challenge. The researchers worked on developing methods and protocols to ensure the models were accurate while still manageable.
Another challenge highlighted was the computational expenses associated with digital twins. Creating and running simulations for digital twins could be computationally intensive, requiring significant resources. The authors explored ways to mitigate these expenses, such as using surrogate models that behaved similarly to the simulation model but were computationally more accessible.
The study also emphasized the importance of establishing universal standards for implementing digital twins. Standardization is crucial to ensure interoperability and compatibility across different fields and industries. The researchers worked towards developing these standards to facilitate the widespread adoption of digital twins.
Furthermore, the researchers emphasized the significance of human input in refining digital twin models. While advanced algorithms and simulations played a crucial role in developing digital twins, human expertise and knowledge were essential for fine-tuning these models. Researchers recognized the need to make trade-offs between model intricacy and usability, ensuring that the models were both accurate and practical for real-world applications.
Lastly, the study highlighted the importance of ensuring data quality consistency across different fields. Digital twins relied on data from various sources, and maintaining data quality was crucial for the accuracy and reliability of the models. Researchers worked on developing methods and protocols to ensure data quality consistency, including addressing data privacy and protection issues.
