Double EWMA‐Based Polynomial Quality Profiles Monitoring
Quality and Reliability Engineering International, 2016 Profile monitoring is useful whenever the quality is described by a relationship between a response and one or more of explanatory variables. It is conventional to refer to this relationship as Quality Profile. Despite the fact that there are numerous examples of the polynomial quality profiles in industrial practice, only few Phase II techniques are ...

An adaptive multivariate functional EWMA control chart
Journal of Quality TechnologyIn many modern industrial scenarios, the measurements of the quality characteristics of interest are often required to be represented as functional data or profiles. This motivates the growing interest in extending traditional univariate statistical process monitoring (SPM) schemes to the functional data setting. This article proposes a new SPM scheme,

New extended exponentially weighted moving average control chart for monitoring process mean
HeliyonIn this article, we develop a new control chart based on the Exponentially Weighted Moving Average (EWMA) statistic, termed the New Extended Exponentially Weighted Moving Average (NEEWMA) statistic, designed to recognize slight changes in the process ...
