Monitoring Non-Parametric Profiles using Adaptive EWMA Control Chart [PDF]
Scientific Reports, 2022 Abstract To monitor the quality of a process in statistical process control (SPC), considering a functional relationship between a dependent variable and one or more independent variables which is denoted as profile monitoring is becoming an increasingly common approach.

A Double Sampling Scheme for Process Mean Monitoring
IEEE Access, 2017 Mean control charts are effective tools for detecting mean shifts of an interesting quality variable in both manufacturing processes and service processes.

Enhancing the performance of EWMA charts [PDF]
Quality and Reliability Engineering International, 2010 Control charts are extensively used in processes and are very helpful in determining the special cause variations so that a timely action may be taken to eliminate them. One of the charting procedures is the Shewhart‐type control charts, which are used mainly to detect large shifts.

PETA KENDALI EWMA RESIDUAL PADA DATA BERAUTOKORELASI
E-Jurnal Matematika, 2019 Control charts with autocorrelation can be overcome by creating control chart with residuals from the best forecasting model. EWMA control chart is a alternative to the Shewhart control chart when detecting small shifts.

Synthetic-type control charts for time-between-events monitoring. [PDF]
PLoS ONE, 2013 This paper proposes three synthetic-type control charts to monitor the mean time-between-events of a homogenous Poisson process. The first proposed chart combines an Erlang (cumulative time between events, Tr ) chart and a conforming run length (CRL ...

On the performance of the adaptive EWMA chart for monitoring time between events
, 2020 In high-quality processes, events related to non-quality rarely occur and the times between these events (TBE) is likely to follow a skewed distribution like the gamma distribution.

A Time Truncated Moving Average Chart for the Weibull Distribution [PDF]
, 2017 A control chart of monitoring the number of failures is proposed with a moving average scheme, when the life of an item follows a Weibull distribution.

Study on Likelihood-Ratio-Based Multivariate EWMA Control Chart Using Lasso
Kvalita Inovácia Prosperita, 2021 Purpose: When applying exponentially weighted moving average (EWMA) multivariate control charts to multivariate statistical process control, in many cases, only some elements of the controlled parameters change.

Towards cross-lingual alerting for bursty epidemic events [PDF]
, 2011 Background: Online news reports are increasingly becoming a source for event based early warning systems that detect natural disasters. Harnessing the massive volume of information available from multilingual newswire presents as many challenges as ...
