Monitoring of time between events with a double generally weighted moving average control chart

Quality and Reliability Engineering International, 2018
AbstractMonitoring of time between events (TBE) instead of the number of events is used in high‐quality processes where the events occur rarely. This article presents a double generally weighted moving average control chart with a lower time‐varying control limit to monitor the TBE (regarded as DGWMA‐TBE chart).

PERAMALAN HARGA SAHAM NVIDIA DENGAN METODE DOUBLE MOVING AVERAGE

Jurnal Ilmiah Informatika Komputer
The movement of NVIDIA's stock price greatly affects investment decisions, so accurate forecasting is very important to influence investment decisions. This research will apply the data mining process for forecasting NVIDIA stock prices using the Double Moving Average method with the application of order 2 and order 3 models.

Development and Evaluation of Control Charts Using Double Exponentially Weighted Moving Averages

International Journal of Quality & Reliability Management, 1992
The double exponentially weighted moving average (DEWMA), which is known in the literature as Brown′s one‐parameter linear method for forecasting is proposed as a control tool for process monitoring and detecting shifts in the process mean. Obtains a closed‐form expression for the asymptotic standard deviation of the proposed DEWMA control statistic ...

Quantitative Analysis on the Bullwhip Effect in a Supply Chain Using Double Moving Average and Double Exponential Smoothing Forecasts

2008 International Symposiums on Information Processing, 2008
In this paper, the bullwhip effect in a multistage supply chain has been analyzed using double moving average and double exponential smoothing forecasts. We find out that double exponential smoothing and double moving average forecasts can sometimes have a variance reducing effect on the supply chain.
