The Research on Statistical Process Control (SPC)

Abstract

With the intense competition in the market, the quality level directly determines the enterprises’ existence and development. Quality management has become the core of enterprise management. In fact, concerning the variation of the qualities, there are some disciplines to follow. We can analyze the reason of the variation and improve the quality management. In this respect, statistical process control (SPC), with less input, quick returns and easy operation, has become the top priority. But during the practical course of statistical process control (SPC), we may encounter many problems. This paper analyzed the detailed process of control chart x  R and control chart X-Rs implementing in an electrochemical CO production company, using some statistical tools to deal with the data, and then according to the data and key factors, find out the weak parts in the production. We think we can achieve effective quality control, which would help the improvements of the quality in return.
