To provide an operation condition presentation method and an operation condition presentation device capable of presenting an operation condition having high influence on a quality before completion of manufacturing of a final product.SOLUTION: An operation condition presentation method includes: a quality prediction step of predicting a defect occurrence probability score of a product when the product is manufactured by an actual operation condition and a preset operation condition by inputting an actual operation condition until a manufacturing midway process of the product and a preset operation condition being set as a standard condition to processes thereafter; an influence level calculation step of calculating a relative influence level of the preset operation condition to the defect occurrence probability score when the defect occurrence probability score exceeds a prescribed value; an operation condition retrieval step of retrieving, on the basis of the relative influence level, a preset operation condition allowing the defect occurrence probability score to be the prescribed value or smaller; and an operation condition presentation step of presenting the retrieved preset operation condition.SELECTED DRAWING: Figure 4 【課題】最終製品の製造が完了する前に、品質への影響の高い操業条件を提示することができる操業条件提示方法および操業条件提示装置を提供すること。【解決手段】操業条件提示方法は、品質予測モデルに対して、製品の製造途中工程までの実績操業条件と、その後の工程について標準条件として設定された設定操業条件とを入力することにより、実績操業条件および設定操業条件で製造した場合の製品の欠陥発生確率スコアを予測する品質予測ステップと、欠陥発生確率スコアが所定の値を超える場合に、欠陥発生確率スコアに対する設定操業条件の相対的影響度を算出する影響度算出ステップと、相対的影響度に基づいて、欠陥発生確率スコアが所定の値以下となるような設定操業条件を探索する操業条件探索ステップと、探索した設定操業条件を提示する操業条件提示ステップと、を含む。【選択図】図４
