Control Charts for Autocorrelated Processes : a Review
نویسنده
چکیده
One of the primary tools used in statistical quality control is the control charts. The standard assumptions that are usually cited in justifying the use of control charts are that the data generated by the in control process are independent and identically distributed. However the independency assumption is not realistic in practice. Data sets collected from industrial processes may have correlation among adjacent observations (autocorrelation). In this case control charts are modified to monitor the autocorrelated process observation. Many scientists made contributions in the area of control charts for autocorrelated data. In the present paper, a comprehensive overview for control charts for autocorrelated data is given by discussing both theoretical developments and practical experiences, and identifying research trends. Finally, historical progression in this field was emphasized and recommendations for future research are suggested.

Monitoring and Diagnosing Multistage Processes: A Review of Cause Selecting Control Charts
A review of the literature on cause selecting charts (CSCs) in multistage processes is given, with a concentration on developments which have occurred since 1993. Model based control charts and multiple cause selecting charts (MCSCs) are reviewed. Several articles based on normally and non-normally distributed outgoing quality characteristics are analyzed and important issues such as economic d...
متن کاملControl chart based on residues: Is a good methodology to detect outliers?
The purpose of this article is to evaluate the application of forecasting models along with the use of residual control charts to assess production processes whose samples have autocorrelation characteristics. The main objective is to determine the efficiency of control charts for individual observations (CCIO) and exponentially weighted moving average (EWMA) charts when they are applied to res...
متن کاملThe quality control chart for monitoring multivariate autocorrelated processes
Previously, quality control and improvement researchers discussed multivariate control charts for independent processes and univariate control charts for autocorrelated processes separately. We combine the two topics and propose vector autoregressive (VAR) control charts for multivariate autocorrelated processes. In addition, we estimateAR(p) models instead ofARMAmodels for the systematic cause...
متن کاملThe Detection of Shifts in Autocorrelated Processes with Moving Range and Exponentially-Weighted Moving Average Charts
The objective of this research is to select the appropriate control charts for detecting a shift in the autocorrelated observations. The autocorrelated processes were characterized using AR (1) and IMA (1, 1) for stationary and non-stationary processes respectively. A process model was simulated to achieve the response, the average run length (ARL). The empirical analysis was conducted to quant...
متن کاملDistribution-Free SPC Methods for Monitoring Variability of Autocorrelated Processes
We consider the problem of monitoring variability of autocorrelated processes. This paper combines variance estimation techniques from simulation literature with two statistical process control charts from statistical process control (SPC) literature. The proposed SPC methods do not require any assumptions on the distribution of the underlying process and use a variance estimate from each batch...
