Abstract
The development of a virtual metrological CT for numerical measurement uncertainty determination at the Institute of Manufacturing Metrology (Friedrich-Alexander-University Erlangen-Nuremberg (FAU), Germany) using the software aRTist 2 by the BAM German Federal Institute for Materials Research and Testing is described. The virtual metrological CT uses a Monte-Carlo approach for numerical measurement uncertainty determination. Results demonstrating that numerical uncertainty determination according to GUM Supplement 1 and in accordance with uncertainty determination according to guideline VDI/VDE 2630 Part 2.1 is possible for selected measurement tasks are presented.
Zusammenfassung
Die Entwicklung eines virtuellen metrologischen CTs (VMCT) zur numerischen Messunsicherheitsbestimmung am Lehrstuhl für Fertigungsmesstechnik der Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) wird beschrieben. Das VMCT basiert auf der Software aRTist 2 der Bundesanstalt für Materialforschung und -prüfung. Das virtuelle metrologische CT benutzt einen Monte-Carlo-Ansatz zur numerischen Messunsicherheitsermittlung. Ergebnisse, die für ausgewählte Messaufgaben die Möglichkeit einer numerischen Messunsicherheitsbestimmung nach GUM Supplement 1 und in Übereinstimmung mit nach der Richtlinie VDI/VDE 2630 Blatt 2.1 bestimmten Messunsicherheiten demonstrieren, werden vorgestellt.

Acknowledgment
The developments benefitted from thesis works by dedicated students who are listed as authors of the relevant publications of the institute quoted in the bibliography. The Division 8.3 (Radiological Methods) at the BAM German Federal Institute for Materials Research and Testing which developed aRTist 2 not only supported the developments by providing a modified version of aRTist 2, but was also very supportive in providing information and through helpful discussions.
