If you do not specify both LSL and USL, the variable _CP_ is assigned a missing value. The process capability index C pk is computed as If you specify only USL, the index C pk is computed as You can ...

Process capability indices (PCIs) have long served as crucial metrics in assessing the performance and quality of manufacturing processes. Recent advances in statistical estimation techniques have not ...

Standard capability indices such as C pk are generally considered meaningful only if the process output has a normal (or reasonably normal) distribution. In practice, however, many processes have ...

This study examines the use of process capability index results to establish sampling strategies for new product cleaning and to minimize the risk of insufficient cleaning. muuraa/shutterstock.com ...

The approach presented in this study uses process capability index results to establish sampling strategies for use with new product cleaning and to efficiently reduce the risk of insufficient ...
