Multivariate Statistical Methods for Total Quality Measurement
نویسنده
چکیده
In this paper, a brief outline of the evolution of the statistical techniques for the measurement of quality is firstly sketched. At the same time, the need for multivariate procedures is justified from both methodological and application points of view and a proposal of non parametric control charts is shown. The attention is then focused on visualising and monitoring quality. The peculiar features of Non Symmetrical Data Analysis methods are shown to fit the demands arising when monitoring quality of multivariate industrial processes. Some research perspectives are finally enhanced.

Multivariate Process Capability Indices (MPCI) show how well a manufacturing process can meet specifica-tion limits when quality characteristics enclose a relative correlation. Process capability is an important and commonly used metric for assessing and improving the quality of a production process. When quality charac-teristics of a product are correlated then an attractive comes close to MPC...
