Virtual experiments and digital twins are key enabling technologies to achieve and realise European strategic policies devoted to sustainability and digitalisation within the complex framework of Industry 4.0 and the European Green Deal. To achieve digitalisation in metrology, trust in simulation results (e.g. by traceable virtual experiments and digital twins) is needed.

Uncertainty evaluation methods need to become compliant with the GUM to ensure traceability in metrological applications, where virtual experiments or digital twins are used. Furthermore, validation procedures are needed for systems with embedded virtual experiment or digital twin. In addition to this, the developed methods need to be transferable to other (metrological) applications. Within the ViDiT project, this transferability is addressed in several industrial case studies.

Besides participants from National Metrology Institutes (NMIs) and academia, there are also several industrial participants part of the ViDiT consortium. Hence, the specific needs from optical industry, metrology instrumentation manufacturers and flow meter manufacturers are directly addressed within the ViDiT project. Furthermore, the project is supported by its Stakeholder Committee.
