Applying the Nonparametric Approach to Build Process Control Charts

Abstract

The procedure for constructing quality control charts based on a nonparametric test is considered. Control charts based on mean, Wilcoxon-Mann-Whitney test, Ansari-Bradley test, standard deviation for real data were built. Comparison of nonparametric control charts with parametric ones made it possible to draw a conclusion about the possibility and effectiveness of using nonparametric control charts on practice.
