Statistical Process Control for Autocorrelated Data on Grid
Assumptions of normality and independence are key assumptions made in the development and use of control charts. However for much industrial data, the assumption of independence is hard to justify. Control charts for the sample mean and sample standard deviation are obtained, when the observations are taken over a grid on a two-dimensional surface. It is assumed that the observations follow an ...
متن کاملThe GLRT for statistical process control of autocorrelated processes
This paper presents an on-line Statistical Process Control (SPC) technique, based on a Generalized Likelihood Ratio Test (GLRT), for detecting and estimating mean shifts in autocorrelated processes that follow a normally distributed Autoregressive Integrated Moving Average (ARIMA) model. The GLRT is applied to the uncorrelated residuals of the appropriate time-series model. The performance of t...

متن کاملModel Building for Autocorrelated Process Control: an Industrial Experience
We show that many time series data are governed by Geometric Brownian Motion (GBM) law. This motivates us to propose a procedure of time series model building for autocorrelated process control that might consist of two steps. First, we test whether the process data are governed by GBM law. If it is affirmative, the appropriate model is directly given by the properties of that law. Otherwise, w...
متن کاملDeveloping New Multivariate Process Capability Indices for Autocorrelated Data
Traditionally, the process capability index is developed assuming that the process output data are independent and follow normal distribution. However, in most environmental cases, the process data have more than one quality characteristic and exhibit property of autocorrelation. We propose two novel multivariate process capability indices for autocorrelated data, NMACp and NMACpm for the-nomin...
