In the quality management of labor insurance shoes, in order to control the quality of labor insurance shoes and the quality of production processes, to understand the quality status and dynamics of each batch of products and each process, it is necessary to investigate and study the quality of labor insurance shoes and production processes. Real quality data and related materials, through a large amount of data to understand and grasp the objective quality of the entire plant. The so-called comprehensive quality management of shoe quality management should try to use data to speak rather than subjective speculation. It is necessary to make inferences and judgments based on the data, and then take countermeasures, formulate measures, and implement effective control. All of this is based on field investigations. There are two ways to do this kind of investigation: one is to conduct all inspections one by one, one by one, one by one; the other is to see all through partial understanding, that is, through the observed local phenomenon, Grasping the essence of things, this is the simple and basic principle of the quality control of labor insurance shoes. The basic feature of this method is to replace the population with a representative partial (partial). It is not a full inspection of a batch of products or processed parts, but a systematic sampling check. That is, from the entire object to be investigated, a certain proportion is randomly drawn according to specifications, patterns, and colors, and it is inspected and measured, and a batch of data is measured, and processed, sorted, grouped, calculated, and displayed to predict the overall population. Quality status. This method is based on the theory of mathematical statistics, and is the specific application of the principle of mathematical statistics in the quality management of labor insurance shoes.
