This article includes the definition of the concept of the quality and how to reach it through the use of some statistical methods for the quality control. The most important of methods is the control charts for the quantitative data of the control chart of the mean and the control chart for the range. Random samples were taken from the free market for the sale of Cement in Zliten and by using certain measures of calculating the weight of the bag of Cement produced. Reliable control charts to control the weight of the Cement bag produced are obtained, and ensured that production conforms to the required specifications in the future. It was found that the process of weighing the bag of Cement produced is in accordance with the specifications set, and that the production process is going as it should be and it is in the case of statistical control. Therefore, these charts are adopted in the future to control the quality in terms of the weight of the Cement bag. Therefore, we recommend that the responsible authorities use these charts in the future by taking samples of production and calculation the mean and the range and drawing their charts to make the appropriate decision in that the production process under control or out of control. |
