استخدام مقدر RMCD الحصين في لوحة السيطرة Hotelling T2 للسيطرة النوعية على الإنتاج : دراسة تطبيقية

Abstract EN

In this study, we used the T² statistic, which is based mainly on the estimator of the computational medium and the common variance matrix of the sample there are outliers in the sample, Can greatly affect the estimated values and therefore used the method of appreciation of the fortified high-efficiency because of its great immunity against the existence of abnormal values in the data, A comparison between the control chart Hotelling T² robust and the control chart Hotelling T² classical to get to the best way, Through practical application of the sample data of the study.

The simulation results showed that the control chart (RMCD) was more efficient than the classical control chart in detecting deviations from the average production process
