数字孪生成熟度模型

The research and application of digital twin have been entering a blowout period. In practice, there are three questions plaguing researchers, engineer and administrators. ①How to tell if an application is a digital twin? ②How to tell whether an existing digital twin can meet the requirements? ③How to optimize a digital twin application to meet the requirements? Unfortunately, there is still a lack of a theoretical system to answer the above questions. To this end, the digital twin maturity model was put forward to help correctly understand and practice digital twin. Six levels of digital twin maturity were established. Then 19 digital twin maturity evaluation factors were proposed for operational digital twin maturity evaluation. The application process of digital twin maturity model was illustrated in detail with two application examples toward unit-level digital twin and system-level digital twin respectively.
