A Modelling Concept for Practice-Oriented Evaluation of Measurement Uncertainty
Keywords: modelling concept, measurement uncertainty, modularisation, cause-and-effect chain, computer aided modelling
The development of a mathematical model for the description of a measurement that accounts for all relevant influences and imperfections is an integral and indispensable part of modern uncertainty evaluation. In practice, modelling is a difficult problem. Here, a general approach to modelling is recommended based on a detailed analysis and a modular design of the measurement system under consideration. This cause-and-effect chain of the measurement is represented by a graphical model which allows for incorporating all influencing quantities involved and their functional relationships. Afterwards, the mathematical model can be derived from the graphical model. This modelling concept can be supported by software. For that purpose a graphical editor is described and its automatic generation of the model equation is discussed.
