Problems solved by technology

[0002] Improving the pass rate of industrial production line products is an important topic of concern in the industry. The main difficulty lies in the inability to accurately control the parameters of each process machine in the production line to maximize the pass rate of products.
[0003] At present, machine control in the industrial field is basically operated according to manual experience, and there are too many machine parameters, and it is impossible for humans to confirm which machine parameters have a great impact on the pass rate, resulting in the inability to predict the impact of the current operation on the product pass rate, or the machine. The control needs to be carried out by operators with certain experience, and different operators will have different operation methods, which cannot be unified, resulting in unstable product qualification rate

Embodiment 1

[0025] Based on the method of improving product qualification rate based on multidimensional decision tree group, the current working conditions are combined with historical data to give suggestions for improving product qualification rate.

[0026] For realizing above-mentioned technical effect, described method comprises:

[0027] S10 collects the basic working conditions that affect the product qualification rate on the production line, and the basic working conditions include equipment parameters and environmental parameters;

[0028] S20 is to construct different decision trees and form a group of decision trees by using production factors as classification standards, wherein the production factors include relatively fixed product categories, models, raw material materials, and the like. Historical data is stored under the decision tree, and the historical data includes historical basic working conditions and one-to-one corresponding product qualification rates.

[0029]...

Embodiment 2

[0033] On the basis of Embodiment 1, the S10 includes S11: find out the main influencing factors in the basic working conditions, that is, calculate the degree of influence of each influencing factor on the product qualification rate and the reliability of the degree of influence. Vectorization and discretization training tools can be used to discretize historical data. Discretization algorithms provide multiple algorithms for selection, such as LBG, K-Means, Mean-Shift, DBSCAN and other clustering algorithms, and then use the information gain rate of information theory Calculate the degree of influence of the basic working conditions on the product qualification rate, and then calculate its reliability according to the TTest algorithm. At the same time, the step S50 includes: the optimization suggestion includes providing the influence degree of a single basic working condition or a combination of basic working conditions in any dimension on the product qualification rate and ...

Embodiment 3

[0036] On the basis of Embodiment 1 or 2, after the decision tree is matched, the current basic working conditions and the actual measured product productivity constitute a dynamic empirical knowledge vector, and the machine learning model iteratively learns the dynamic knowledge vector to support Dynamic growth of decision trees.

[0037] The machine learning model also has a dynamic experience knowledge vector iterative learning function, that is, the machine learning model fine-tunes the value of the basic working conditions on the basis of the existing historical data, and analyzes the influence of the data trend of each basic working condition on the pass rate , learn the fine-tuned product pass rate, so that it can learn a better experience beyond the experience of manual adjustment.

Abstract

The invention discloses a method for improving the product qualification rate based on a multi-dimensional decision tree group. The method is characterized by taking a production factor as a classification standard to construct different decision trees so as to form a multi-dimensional decision tree group; providing multi-dimensional optimization suggestions, including highest qualification rate configuration suggestions; determining the influence factors which have great influence on the product qualification rate can according to the influence degree of the influence factors; performing auxiliary decision making, so as to improve the product qualification rate, reduce correction, and improving work efficiency improvement; or directly giving the suggestions that the configuration is changed at least under the condition of higher qualification rate. The method supports real-time data updating and dynamic growth of the decision trees; basic working conditions can be finely adjusted through machine learning, so that the productivity change after fine adjustment can be learned; and at the same time, due to the fact that the number of equipment parameters is large, the decision tree group needs large space while the decision tree group and the machine learning module can be switched in different memory spaces, and needed data can be flexibly dispatched or learned in the corresponding memory space.
