Information Technology Digital Twin Capability Maturity Model

1 Scope

GB/T 46237-2025 is the Chinese national standard covering grading how far a digital twin has actually got - from a static model through the connected, synchronised and predictive levels to one that acts back on the physical asset, with the criteria for each level and the assessment method. Most things sold as digital twins sit at the lower levels. First edition, in force from 1 May 2026. Issued on 5 October 2025, it has been in force since 1 May 2026.

This document outlines the structure of the digital twin capability maturity model, specifying maturity levels, capability domains, and capability requirements. This document applies to the planning, construction, and evaluation of digital twin systems.
