“…In their literature review, the evolution process of digital twins was divided into four stages: the digital twin concept was introduced and focus was directed on R&D in the first stage (Information Monitoring Model, 1985-2002, connected to a web browser and applied to multinational companies in the second stage (Digital Simulation, 2003-2014, connected to devices for effective virtual-physical data transmission in the third stage (IoT Implementation, 2014-2016), and real-time simulation, optimization, and defect detection using artificial intelligence and machine learning in the fourth stage (Decision-Making Tools, 2017-present) [11]. Kukushkin et al collected digital twin papers from 1993 to 2022 and analyzed LDA, machine learning-based topic modeling, and Bidirectional Encoder Representations from Transformers (BERTopic) [12]. Consequently, the digital twin papers' keywords were Industry 4.0, Internet of things, machine learning, simulation, cyber-physical systems, modeling, digitalization, deep learning, optimization, etc.…”
