Abstract

This paper presents a way to assess processes where more quality characteristics are observed. The method used concerns multivariate capability indices supported by graphical methods. The emphasis is placed on thorough testing of conditions that validate such procedure. The methodology is illustrated on metallurgical data related to a casting which is assessed by two quality characteristics – ultimate tensile strength (X1 in pascals) and yield strength (X2 in pascals).

Keywords: Metallurgy, capability, normality, homogenity, outliers, centralization, process stability.
