| Abstract | ||
| According to the control charts as one of the statistical methods that lead to monitoring and improving the efficiency of the production process, there for we use control charts for mean and range for drawing control charts for compressive strength of bricks in al-Qadisya brick factor. The compressive strength tests are down for ten patch no .during march 2012, each patch contain ten samples, the LCL and UCL for brick compressive strength are (109.494, 140.892) kgcm2 respectively while Iraqi specification limits are 110 kgcm2 for type B that close nearly from LCL of factory limits that gives an idea for production type in the factory is most nearly from type B. By using the control charts we can follow the compressive strength of bricks inside the factory where if the results of tests are outside control chart limits we must investigate and correct the deviation. | ||
