Introduction to Statistical Process Control
Statistical Process Control Statistical Process Control is a process control tool based on mathematical statistics.It analyzes and evaluates the production process, discovers timely signs of systemic factors based on feedback information, and takes measures to eliminate their impact so that the process remains in a controlled state affected only by random factors, in order to achieve the purpose of controlling quality.
In the production and manufacturing process of enterprises, we often need to collect production data, then process the data, and finally present the processed data, dispatch instructions or decisions in the form of reports and data screen, giving reasonable and scientific decision-making suggestions to the leadership.
This project mainly uses Windows 10 + Visual Studio 2019 + Windows Form Application (.Net Framework) to implement Six Sigma mode data decision-making and Chart report module display, mainly for continued learning and research.
