An enhanced nonparametric quality control chart with application related to industrial process
Scientific ReportsIn various practical situations, the information about the process distribution is sometimes partially or completely unavailable. In these instances, practitioners prefer to use nonparametric charts as they don’t restrict the assumption of normality or ...

WSEAS TRANSACTIONS ON MATHEMATICSIn the past, the control chart served as a statistical tool for detecting process changes. The Exponentially Weighted Moving Average (EWMA) control chart is highly effective for detecting small changes. This research introduces the Extended Exponentially Weighted Moving Average (Extended EWMA) control chart for the Autoregressive and Moving average ...

Average Run Lengths of an Optimal Method of Detecting a Change in Distribution
The Annals of Statistics, 1987 The author, Ann. Stat. 13, 206-227 (1985; Zbl 0573.62074), gave a second- order asymptotically optimal solution to the classical change point problem. In the present paper, he dicusses asymptotic operating characteristics of this and related procedures. Asymptotic expressions for the expected stopping times are obtained.

Investigating Effect of Autocorrelation on Monitoring Multivariate Linear Profiles
International Journal of Industrial Engineering and Production Research, 2012 Profile monitoring in statistical quality control has attracted attention of many researchers recently. A profile is a function between response variables and one or more independent variables.

An efficient MEWMA chart for Gumbel's bivariate Pareto distribution
Journal of Taibah University for ScienceControl charts play a vital role in process monitoring to ensure the product's desired standards. Due to rapid improvements in data collection methods, multivariate charts are preferred over univariate charts.

Linear Profile Monitoring in the Presence of Non-Normality and Autocorrelation
International Journal of Industrial Engineering and Production Research, 2010 In an increasing number of practical situations, the quality of a process or product can be effectively characterized and summarized by a profile. A profile is usually a functional relationship between a response variable and one or more explanatory ...
