Process yield, the percentage of processed product units passing inspection, is a standard numerical measure of process performance in manufacturing industry. Based on the expression of process yield, Boyles (1994) presented a yield-measure index, S<SUB align="right"><SMALL>pk</SMALL></SUB>, for normally distributed processes. In...</small></sub>

Process capability analysis is arguably one of the most important engineering decision-making tools. The purpose of this research is to create a nonparametric exponentially weighted moving average (EWMA) capability control chart for monitoring S-type short-term process capabilities. Simulations...
