Analysis of Costs at the Production of Finishing Works with Guaranteed Quality Level

Abstract

The aim of the work is to analyze the cost of finishing works. Object of research is paint application process on building products and design. Information is provided on the results of the cost analysis in the process of painting the surface of building products and structures, depending on the level of defectiveness at each stage of the process. Recommendations are given to improve the efficiency of the painting process, the application of statistical methods for managing product quality to the analysis of the process for obtaining paint coatings with specified properties. Determined, that in terms of the number of standard deviations and the level of defectiveness, the greatest attention is required by the surface cleaning operation, the priming of the cleaned surface and hardening of weak bases, as well as application of putty on the surface. Thus, consideration of economic costs on each stage of the process will allow the enterprise to find reserves for increasing production efficiency. The real way to reduce financial losses is to increase the number of standard deviations of quality indicators in the tolerance field, which is recommended by the six sigma methodology. To successfully reduce the cost of correcting defects, it is necessary methodology “six sigma”, statistical methods of control and quality management of products, carry out preventive and corrective actions, as well as to evaluate failures leading to a decrease in profits, regardless of the reasons for their being caused.
