Randomized trial evaluates new CUSUM control charts for monitoring location and scale parameters, suggesting enhanced performance in various distributions.

Key Points

This paper aims to develop and evaluate two nonparametric CUSUM control charts for detecting shifts in location and scale parameters.
Developed two Phase II CUSUM control charts using Lepage-type statistics.
The first chart combines van der Waerden and Ansari–Bradley tests, while the second combines van der Waerden and Mood tests.
Evaluated performance based on average run length under four different distributional models.
The CUSUM chart using van der Waerden and Mood tests consistently outperforms its competitors in all considered distributions.
Statistical design factors, especially reference values, significantly affect chart performance.
Demonstrated practical applications in a hard-bake manufacturing process and customer service time process.
