Assistance for the determination of Measurement Uncertainty Analysis. Development of a prototypical implementation within the existing framework

Master's Thesis from the year 2015 in the subject Computer Science - Applied, grade: 2, University of Applied Sciences Coburg, language: English, abstract: The project shall contribute to the further development of a prototypical implementation for an assistance solution supporting measurement uncertainty analysis within the existing framework. The main tasks in this project will be:

Familiarisation with the topic of measurement uncertainty analysis and the handling of software GUM Workbench®, definition of an design outline for the user support during measurement uncertainty analysis, including an analysis of required supporting function and the subsequent definition of a possible system structure, selection of one aspect in the process and development of a draft for an adequate support solution, containing elements to enable partial automation or increase of efficiency for the process step as well as explanatory information for the users, prototypical implementation and testing of the defined elements within the outlined framework.

In the "Guide to the Expression of Uncertainty in Measurement" (GUM), jointly issued by ISO and BIPM, a standard procedure for the determination of measurement uncertainty is defined. Yet, although this document is supported by many international organisations and the consideration of measurement uncertainty is of high importance in many fields of application, ranging from industrial quality control to scientific research, still often the determination of measurement uncertainty is omitted.

This is mainly due to difficulties of the metrologists to apply the general rules of the GUM to the task at hand. To ease this task and support the determination of measurement uncertainty, the software GUM Workbench® performs all required mathematical evaluations based on a model of the measurement. Additionally, a concept for an assistance system as well as a graphic modelling editor has been developed to facilitate the definition of a suitable model.

But, the existing concepts are not yet fit for practical testing under industrial conditions.
