EWMA Dispersion Control Charts for Normal and Non-normal Processes

Process monitoring through control charts is a quite popular practice in statistical process control. This study is planned for monitoring the process dispersion parameter using exponentially weighted moving average (EWMA) control chart scheme. Most of the EWMA dispersion charts that have been proposed are based on the assumption that the parent distribution of the quality characteristic is nor...

Fast initial response features for EWMA Control Charts

The exponentially weighted moving average (EWMA) control chart became very popular during the last decade. It is characterized by simple handling and good performance. It turns out, however, that the most popular EWMA scheme with fixed-width control limits – the asymptotic control limits are taken and do not change over time – detects early changes rather slowly. For the competing CUSUM chart t...

Comparison of single EWMA-type control charts based on Economic- statistical design

Abstract A single exponentially weighted moving average (EWMA) chart is effectively used for monitoring the process mean and variance simultaneously. In this paper, three single EWMA-type control charts including sum of square EWMA (SS-EWMA), maximum EWMA (MaxEWMA), and EWMA-semicircle (EWMA-SC) charts are compared under Lorenzen and Vance’s cost model integrating Taguchi’s loss function. The o...

Multivariate variability monitoring using EWMA control charts based on squared deviation of observations from target

Recent research works have shown control statistics based on squared deviation of observations from target have the ability to monitor variability in both univariate and multivariate processes. In the current research, the properties of the control statistic t S that has been proposed by Huwang et al. (Journal of Quality Technology 2007; 39: 258-278) are first reviewed and three new t S -based ...

Detection of Denial-of-QoS Attacks Based On χ Statistic And EWMA Control Charts

In this paper, we describe a method of detecting denial of Quality of Service attacks on DiffServ networks. Our approach focusses on real time and quick detection, scalability to large networks, and a negligible false alarm generation rate. Sensors sample QoS parameters like bit rate, packet dropping rate, and jitter of specific Virtual Leased Line (VLL) flows at predefined strategic points in ...
