Title:
PREDICTION DEVICE, CALCULATION DEVICE, MANUFACTURING DEVICE, AND MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/004880
Kind Code:
A1
Abstract:
The present invention reduces variation in performance of a polymer being manufactured. This prediction device (10A) is for predicting a performance value indicating performance of a polymer in a polymerization tank after raw materials are added therein when manufacturing the polymer. The prediction device is provided with: an acquisition unit (111) that acquires, as a prediction observation value, an observation value observed as a value related to manufacturing of a polymer in current manufacturing of the polymer; and a prediction unit (112) that, by using a relation between an observation value obtained in past manufacturing of a polymer of the same kind as the polymer and a performance value of the polymer at a predetermined timing in the past manufacturing, predicts the performance value of the currently manufactured polymer at the predetermined timing from the prediction observation value acquired by the acquisition unit.
