Virtual Measurement

A virtual measurement is a quantitative result and its uncertainty, obtained primarily by computer simulation or computer-assisted measurements. Examples of virtual measurements include computational models of physical systems and visualizations of the results. The Virtual Measurement Systems Program introduces metrology constructs - standard reference computations, uncertainty quantification, and traceability - into scientific computation and computer-assisted measurement technologies. As with physical measurement systems, development of a virtual metrology infrastructure will result in predictive computing with quantified reliability. In turn, this will enable improved decision making based on results of computer simulations.

Programs/Projects:

 

Virtual Measurement System projects are organized along two principal research areas.
