Six Sigma represents Cp of 2.0.在流程能力分析方面被广泛应用的能力指数,在数值方面它可能是从零到显示更强有力流程的无穷大之间的某个点。六个西格玛代表的是Cp=2.0。 Cpk:A process capability index combining Cp and k (difference between the process mean and the specification mean) to determine ...
CP, CPK, PP, and PPK are statistical process capability indices used to evaluate the ability of a process to consistently produce products or services within specified tolerances. These indices provide a numerical measure of process performance and are widely used in Six Sigma and other quality man...

Cp and Cpk are commonly referred to as process capability indices. They are statistical measures used in process capability analysis to evaluate the ability of a process to produce output within specified limits. First, let's understand what Cp is. Cp, or process capability, is the ratio of ...
1. Do Both CP and Cpk Calculations By comparing thepotentialcapability with the actual capability, you will understand what, if anything, you need to do to be sure you remain in spec. 2. Use the CP to Compare Different Parts of the Organization ...

Case 1 in this diagram shows a highly repeatable machine since all measurements are tightly clustered and "right on target". The average variation between each point, known as the standard deviation (written as sigma, or the Greek symbol σ), is small. However, a small standard deviation ...

In this paper, lower 100(1-)% confidence limits for Cp and Cpk were developed for autocorrelated processes. Simulation was used to generate the empirical sampling distribution of each estimator for various combinations of sample size (n), autoregressive parameter (), true index value (Cp or Cpk...
