Process Capability Evaluation for a Non-normally Distributed One [PDF]
Engineering and Technology Journal, 2013 The common process capability indices (PCIs) Cp, Cpk, Cpm are widely used in practice. The use of these PCIs is based on the assumptions that process is in control and its output should be normally distributed.

ADJUSTING OFF – CENTERING PROCESS FOR A BLOW MOLDED PLASTIC PRODUCT BY USE OF WINQSB SOFTWARE
Journal of Engineering, 2023 In most manufacturing processes, and in spite of statistical control, several process capability indices refer to non conformance of the true mean (µc ) from the target mean ( µT ), and the variation is also high.

A process capability index for zero-inflated processes
International Journal of Engineering, Science and Technology, 2022 The proportion of zero defect (ZD) outputs is as an integral characteristic of a zero-inflated (ZI) process or high quality process. Different ZI processes can almost equally satisfy the same USL of number of defects but they can produce substantially different proportions of ZD products.

A New Non-parametric Process Capability Index [PDF]
2018 IEEE International Conference on Prognostics and Health Management (ICPHM), 2018 Process capability index (PCI) is a commonly used statistic to measure ability of a process to operate within the given specifications or to produce products which meet the required quality specifications. PCI can be univariate or multivariate depending upon the number of process specifications or quality characteristics of interest.
