Abstract: Distribution-free control charts can play a useful role in this research, as a parametric model assumption often cannot be adequately verified. For benchmarking reasons, the non-parametric EWMA-chart is included in the comparisons. However, results provide evidence in favour of using distribution-free charts in practice. In this research article we construct the non- parametric exponentially weighted moving average (EWMA) control limits for based on Kruskal-Wallis test with process capability for the data on balance with the presently available control limits.
Keywords: Control chart, Kruskal-Wallis test and Process capability.
