Process capability indices for non-normal distribution
Capability Indices for Non-Normal Distribution using Gini’s Mean Difference as Measure of Variability
... ABSTRACT This paper investigates the efficiency of Gini’s mean difference (GMD) as a measure of variability in two commonly used process capability indices (PCIs), i.e., Cp and Cpk. A comparison has ...
