Since the effort of modelling as well as quantifying the measurement uncertainties depend on the number of influencing quantities considered, the aim of this study is to determine relevant influencing quantities and to remove irrelevant ones from the dataset. Design/methodology/approach In this work, it was investigated whether the effort of modelling for the determination of measurement uncertainty can be reduced by the use of feature selection (FS) methods. For this purpose, 9 different FS methods were tested on 16 artificial test datasets, whose properties (number of data points, number of features, complexity, features with low influence and redundant features) were varied via a design of experiments. Findings Based on a success metric, the stability, universality and complexity of the method, two FS methods could be identified that reliably identify relevant and irrelevant influencing quantities for a measurement model. Originality/value For the first time, FS methods were applied to datasets with properties of classical measurement processes. The simulation-based results serve as a basis for further research in the field of FS for measurement models. The identified algorithms will be applied to real measurement processes in the future.}, language = {en} } @article{Weigand1994, author = {Weigand, Christoph}, title = {Optimal Production Schedule for a K Products Single Machine Problem}, series = {Economic Quality Control. 9 (1994)}, journal = {Economic Quality Control. 9 (1994)}, isbn = {0940-5151}, pages = {91 -- 101}, year = {1994}, language = {en} } @article{Weigand1991, author = {Weigand, Christoph}, title = {Optimale Maschinenjustierung}, series = {Technische Hochschule / Bibliothek: Wissenschaftliche Zeitschrift. 37 (1991)}, journal = {Technische Hochschule / Bibliothek: Wissenschaftliche Zeitschrift. 37 (1991)}, isbn = {0043-6917}, pages = {167 -- 175}, year = {1991}, language = {de} } @article{Weigand1991, author = {Weigand, Christoph}, title = {A Solution to the Scheduling Problem Taking into Account Quality}, series = {Operations research '91 : extended abstracts of the 16th Symposium on Operations Research held at the University of Trier at September 9 - 11, 1991 / [GM{\"O}OR].
