DTMN a Modelling Notation for Digital Twins.

Modelling and developing digital twin solutions is a growing and promising trend followed by enterprises with the ambition to improve decision-making and accelerate risk assessment and production time. However, as a current emerging trend, there is no recognised standard nor a unique solution that provides support for all the characteristics of a digital twin. This article builds upon the result of a literature review that we conducted to extract the main characteristics attributed to Digital Twins. The identified characteristics guided the proposal of a Digital Twin Modelling Notation (DTMN). In this work we present the DTMN meta-model supported by a graphical modelling notation. This modelling notation can be used as a starting point to design and reason about Digital Twin solutions.
