Product quality prediction method and system in production and manufacturing process, medium and equipment

Abstract

The invention relates to a product quality prediction method and system in a production and manufacturing process, a medium and equipment. The method comprises the following steps: carrying out data preprocessing on acquired sample data; determining a key process; creating a key process prediction model for the key process; training and correcting the key process prediction model; performing key process prediction by utilizing the key process prediction model to obtain a prediction result of the key process; creating a whole-process prediction model of the whole process according to the prediction result of the key process; training and correcting the whole process prediction model; and predicting the product quality by using the whole-process prediction model. According to the method, thekey process in the product manufacturing process is predicted, and the prediction result of the key process is used as an input quantity for predicting the overall product quality, so that the accuracy of product quality prediction is improved, and the production and manufacturing process is controllable; and the product problem source can be traced conveniently, so that the technological processis improved.

Description

technical field [0001] The invention relates to the technical field of product quality prediction, in particular to a method, system, medium and equipment for product quality prediction in a manufacturing process. Background technique [0002] At present, in the process of industrial production, high-quality products can not only bring high profits to enterprises, but also enhance the popularity and recognition of corporate brands. pivotal role.
