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.

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.
