Research and Application of SPC in Process Quality Control of Tobacco Industry

Statistical process control (SPC) technology is a modern process quality management technology integrating production technology and scientific management. It uses the principle of probability theory of mathematical statistics and applies statistical methods to monitor each stage of the production process. It can find the abnormal situation in the production process in time and take measures to improve it in time, so as to achieve the purpose of improving and ensuring the quality. In the tobacco industry, SPC is introduced for process quality control, and Plato, three-phase control chart, columnar bubble chart and other quality control tools are used to monitor, analyze and judge whether the cigarette production process is in a stable and controllable state, and measure and record the process quality, so as to effectively control and manage the quality process, and ultimately greatly improve the production quality management level.
