تحليل مقدرة العملية الإنتاجية الخاضعة للتوزيع الطبيعي لخريطة المراقبة للمتغيرات

Abstract EN

We tried through this study, which was carried out at sotrifet-tiaret institution in Tiaret, demonstrating the extent to which the institutions are able to meet the outputs of the industrial process and their suitability to the required specifications, this is in order to gain customer satisfaction and maintain its market share through the quality of its products as all observations of the production process were within the upper and lower control limits of the arithmetic mean and range chart which means that it is statistically stable, but this stability does not mean that the output of the industrial process is identical to the production specifications therefore, the ability of production processes must be analyzed using the indicators of the ability that has the ability to detect defects in industrial outputs by knowing the extent to which actual performance matches the required specifications , all of these indicators were less than the correct one, which means that the institution does not have an actual ability to produce according to specifications.
