Title:
SYSTEM AND METHOD FOR PREDICTING PROCESS CHANGES BY REFLECTING KEY FACTORS IN COMMERCIAL CHEMICAL PROCESS
Document Type and Number:
WIPO Patent Application WO/2022/231283
Kind Code:
A1
Abstract:
The present invention relates to a system and a method for predicting process changes by reflecting key factors in a commercial chemical process, wherein key factors are selected according to process operating conditions and applied to a prediction model so that the prediction accuracy of process changes can be increased. The present invention comprises: a key factor extraction and individual tag importance backup unit that extracts yield key factors by calculating the importance for each tag, and backs up the importance data for each tag; and a yield prediction model training and yield prediction performing unit that performs yield prediction model training by using individual tag importance calculation results calculated from the backed-up importance data of the key factor extraction and individual tag importance backup unit, and performs yield prediction so as to output a yield prediction result, evaluates performance, and selects an optimal prediction model.
