The effect of gauge measurement capability on MC_p and its statistical properties

Abstract

Purpose

The aim of this paper is to consider the effect of gauge measurement capability on the multivariate process capability index (MC_p).

Design/methodology/approach

With respect to measurement capability, the paper investigates the statistical properties of the estimated MC_p and considers the effect of gauge measurement capability on the lower confidence bound, hypothesis testing, critical value and power of testing for MC_p at the mentioned state.

Findings

The results show that gauge measurement capabilities will notably change the results of estimating and testing the process capability index.

Originality/value

The research would help quality experts to determine whether their processes meet the required capability, and to make more reliable decisions.
