Application of the methodology of readiness levels for the lean development of digital twins of complex engineering systems

Due to the complexity of full-scale object modeling and the need to use advanced computing technologies, the digital twin development process may require significant time, financial and human resources. Therefore, it is important for lean management of digital twin development to classify them by functionality, determine the current technology readiness level (TRL), and monitor its dynamics over short periods of time. A description of the life cycle stages of digital twins virtual models and adapted conditions to achieve technology readiness level are proposed. The use of the formalized TRL metric for detailed project planning by specific results reduces the development time, costs, and improves the quality of the results.
