Implementation of statistical process control methods as a way to reduce production costs and improve product quality

Abstract

The article analyzes various situations of building a quality assurance system at an enterprise. The article includes the analysis of influence of various factors on the decision-making on the principles of building a quality assurance system, the conclusion about the need to build the quality assurance system aimed not at preventing the assembly of parts with deviations but on creating a process producing parts without deviations. The stages of implementation of the statistical process control system are considered. Moreover, the article analyzes the characteristics of measuring methods and tools that can be included into the quality assurance system, and examines the various process states allowing making a conclusion about the possibility of their controllability. The example of a comprehensive solution of the statistical process control system is given.
