To identify impacts caused by updating models for each site, corresponding to input at each site.SOLUTION: Concerning a pre update model and an update candidate model each, an index model MA and an index model MB indicating relations between input (evaluation data) and evaluation for output thereof are generated, a difference model MI indicating a change in the indices to the input is generated on the basis of a difference between the index model MA and the index model MB, actual input data from each on-site operation device to which the pre update model to be updated is applied is obtained, and an impact level corresponding to each of the on-site actual input data is identified on the basis of the obtained actual input data and the difference model MI.SELECTED DRAWING: Figure 11 【課題】モデル更新による影響を、各現場での入力に応じて、現場毎に特定する。【解決手段】更新前モデル及び更新候補モデルの各々について、入力（評価データ）とその出力についての評価との関係を示す指標モデルＭＡ及び指標モデルＭＢを生成し、指標モデルＭＡと指標モデルＭＢとの差分から、入力に対する指標の変化を示す差分モデルＭＩを生成しておき、更新対象の更新前モデルが適用されている現場の運用装置の各々から実入力データを取得し、取得した実入力データと差分モデルＭＩに基づいて、各現場の実入力データに応じた影響度を特定する。【選択図】図１１
