Exponentially weighted moving average acceptance charts

Quality and Reliability Engineering International, 2000
A description of acceptance charts, which use subgroup averages, was published by Freund in 1957 (Industrial Quality Control 1957; (October): 13–23). The purpose of these charts is to evaluate a process in terms of whether or not it could be expected to satisfy product tolerances.

Hybrid Exponentially Weighted Moving Average Chart Using Exponential Distribution

Journal of Computational and Theoretical Nanoscience, 2017
In this manuscript, a new hybrid exponentially weighted moving average chart using the exponential distribution is given. The complete structure of the proposed control chart is given. A Monte Carlo simulation is given for the proposed control chart. The necessary measurements to show the performance of the proposed chart are also given.

The Exponentially Weighted Moving Average

Journal of Quality Technology, 1986
The Shewhart and CUSUM control chart techniques have found wide application in the manufacturing industries. However, workpiece quality has also been greatly enhanced by rapid and precise individual item measurements and by improvements in automatic dynamic machine control.

Forecasting Sales by Exponentially Weighted Moving Averages

Management Science, 1960
The growing use of computers for mechanized inventory control and production planning has brought with it the need for explicit forecasts of sales and usage for individual products and materials. These forecasts must be made on a routine basis for thousands of products, so that they must be made quickly, and, both in terms of computing time and ...

Exponentially Weighted Moving Average (EWMA) with Irregular Updating Periods

Journal of the Operational Research Society, 1993
Summary: This paper shows how to modify the smoothing constant for use in an Exponentially Weighted Moving Average system, when data has to be combined either across a number of periods, or is available from only a fraction of a normal forecast review interval.

Inference for asymmetric exponentially weighted moving average models

Journal of Time Series Analysis, 2019
The exponentially weighted moving average (EWMA) model in ‘Risk‐Metrics’ has been a benchmark for controlling and forecasting risks in financial operations. However, it is incapable of capturing the asymmetric volatility effect and the heavy‐tailed innovation, which are two important stylized features of financial returns.

Feedback adjustment using exponentially weighted moving average schemes

Journal of Al-Rafidain University College For Sciences ( Print ISSN: 1681-6870 ,Online ISSN: 2790-2293 ), 2021
In this study, we discuss the use of exponentially weighted moving average (EWMA) schemes in feedback adjustment for process improvement. By application the different measures of dispersion yield different optimal values. In particular it is suggested that a robust statistic based on the median is more appropriate than the usual mean of square error ...
