Adaptive Nonparametric CUSUM Control Chart
|
Abstract:
Fixed thresholds and slow response to end of the anomalies are two shortcomings of the traditional CUSUM control chart.Three measures are taken in this paper to solve both problems.Firstly,a fixed threshold was set to eliminate outliers and simplify the detection of obvious anomalies.Secondly,the filtered data were smoothed and transformed based on the simple moving average method and the Chebyshev inequality.Lastly,an adaptive threshold was set according to the transformed results,and the decision-making p...
