Abstract

The invention discloses a method for obtaining a control chart of a product. The method comprises the following steps: obtaining an iteration function value corresponding to a target product; when the number of iterated operations does not reach the preset number of iterated operations, adjusting a preset constraint expectation weight lifting matrix criterion according to the number of iterated operations to obtain an adjusted constraint expectation weight lifting matrix criterion; using the adjusted constraint expectation weight lifting matrix criterion and a preset constraint condition to process the iteration function value to obtain an updating point function value; and performing iterative operation by using the updated point function value until the updated number of iterated operations reaches a preset number of iterated operations, and obtaining a control chart of the target product according to the iterative function value of the last iterative operation. The invention further discloses a product control chart obtaining device, terminal equipment and a storage medium. By using the method provided by the invention, the iteration function value of the last iteration operation is improved, and the technical effect of improving the accuracy of the control chart of the product is realized.

Description

technical field [0001] The present invention relates to the technical field of product data processing, in particular to a method, a device, a terminal device and a storage medium for obtaining a control map of a product. Background technique [0002] "Statistical Process Control" is one of the most popular and effective quality improvement methods today. Statistical process control technology mainly refers to the use of Shewhart's process control theory, that is, the control chart to monitor the various stages of the product in the production process, that is, the quality characteristics of the process, and analyze the trend of the quality characteristics according to the point distribution on the control chart. Preventive measures to ensure that the production process is in a state of statistical control, so as to achieve the purpose of improving and ensuring quality. [0003] The "mean-standard deviation" control chart has been widely used in the analysis of the mean val...
