The Control Over The Quality of The Brick Properties in The Factories (Alqadissyah Brick Factory – Case Study)

Abstract

It is important to confirm the production (bricks) with factory private stratification throw the quality monitoring for the continues production process in the factory after we know a limits of the factory production so when there is any deviation from these limits indicate the index that an operation process is out of the control and we must do the correction that for reproduction around the factory’s quality limits .A control charts for proportion was used in this search for application it to the efflorescence characteristic of bricks ,Alqadissiah brick factory was chosen us a case study , throw of drawing control chart for efflorescence characteristic proportion, it is shown that the upper limit is 43.62%, that mean 43.62% from production be in (meddle efflorescence ) and may not be upper than this .when the points is showing we find there inside the limits ,that mean the production process is under control and that after drawing second chart by neglect four points (three of there)are outside limit because order causes related to put up a new water system to filter water that using in the knead, and (first point) was taken before put up a new water system...
