Možnosti praktického využití metod profile monitoringu

Abstract

In many applications, process or product quality is best characterized and summarized by a functional relationship between a response variable and one or more explanatory variables. Profile monitoring is used to understand and control the stability of this relationship over time. At each sampling stage, a set of data points are observed, which can be represented by a curve (or profile). In some calibration applications, the profile can be adequately represented by a simple linear regression model, while in other applications more complex models are required. The purpose of this paper is to review research on the use of control charts to monitor profiles, process and product quality.
