Summary:To improve control accuracy of equipment of a control target plant.SOLUTION: An operation control support device comprises: a control value prediction model construction unit 121 which generates a control value prediction model 221 for calculating a prediction control value 222, which is a prediction value of a control value, on the basis of actual measurement data 211 and actual control data 212; a prediction control value calculation unit 122 which calculates the prediction control value 222; a result value prediction model construction unit 131 which generates a result value prediction model 231 for calculating a prediction result value 232, which is a prediction value of a result value, on the basis of the actual measurement data 211, the actual control data 212, and actual result data 213; a prediction result value calculation unit 132 which calculates the prediction result value 232; and a correction unit 141 which calculates a corrected prediction control value 251 by correcting the prediction control value 222 on the basis of the calculated prediction result value 232, and outputs the corrected prediction control value 251 to a plant P.SELECTED DRAWING: Figure 1 【課題】制御対象プラントの機器の制御精度を向上させることを課題とする。【解決手段】実績計測データ211と、実績制御データ212とを基に、制御値の予測値である予測制御値222を算出するための制御値予測モデル221を生成する制御値予測モデル構築部121と、予測制御値222を算出する予測制御値算出部122と、実績計測データ211と、実績制御データ212と、実績結果データ213とを基に、結果値の予測値である予測結果値232を算出するための結果値予測モデル231を生成する結果値予測モデル構築部131と、予測結果値232を算出する予測結果値算出部132と、算出された予測結果値232を基に、予測制御値222を補正することで補正済み予測制御値251を算出し、補正済み予測制御値251をプラントPへ出力する補正部141と、を有することを特徴とする。【選択図】図1
