Using statistical methods results of acceptance testing of products from autoclave cellular concrete of the enterprises of the Belgorod region were analyzed according to the measured compressive strength and density. It was found that when these indicators conform the regulations, their oscillations reach the frontiers of normal statistical distribution. It is shown that statistical methods can serve as a tool to control the quality of products and for finding problems in the production process with identifying the most important of them. The most expected causes of quality deterioration were identified. Recommendations for enterprise to bring the investigated process under the stable conditions were given. Thus it was shown that it is not always correct to judge the stability of manufacturing prosess only by output of quality products with a minimum level of defects. As an important tool for adjustment of production activities may be the use of statistical methods of quality management that can improve the efficiency of industrial enterprises. |
