Conventional process capability indices (PCIs) are usually determined under the assumption that quality characteristics follow a normal distribution. If a process does not follow a normal distribution, however, conventional PCIs do not provide valid measures of process capability, especially in terms of...
A solid, rigorous, yet comprehensible analysis of process capability indices, this work bridges the gap between theoretical statisticians and quality control practitioners, showing how an understanding of these indices can lead to process improvement. 我来说两句 短评 ··· 热门 还没人写过短评呢...
The capability indices Cp, CPU, CPL, k and Cpk are presented and related to process parameters. These indices are shown to form a complementary system of measures of process performance, and can be used with bilateral and unilateral tolerances, with or without target values. A number of ...
This module discusses the process capability indices that are commonly used asbaseline measurementsin theMEASUREphase and in theCONTROLphase. Theconcept of process capabilitypertains only to processes that are in statistical control. There are two types of data being analyzed: ...

Process capability indices Cp, Cpk, and Cpm are still nowadays widely used in industry鈥攖hanks to their easy formulation and implementation. This paper aims to give new mathematical insights in order to support their use in decision-making via hypothesis testing. The minimum sample size usually ...
The literature on process capability indices for discrete data is rather limited. In this paper, we propose transformation techniques for Poisson and binomial data. The transformed data are approximately independent and normally distributed. Therefore, the practitioner is able to compute the usual ...
