Approximation Formulas for the Lower Confidence Limits of Process Capability Indices

Abstract

The process capability indices are very often used in the activities of quality control.Especially, in the processes of Japanese manufacturing industries, a lot of researchers and / or workers often evaluate those indices to check whether their processes are satisfactory or not.Assuming the population distribution of the quality characteristic IS normal one N (jJ., (J 2) with mean jJ. and variance (J 2, the process capability indices are defined as follows:(i) when there is only the upper specification limit Su CPU = Su -jJ. 3 (J (ti) when there is only the lower specification limit SL CPL = jJ.-
