To appropriately determine the necessity of update of a diagnosis model in an anomaly sign diagnostic device.SOLUTION: An anomaly sign diagnostic device 100 is provided with: a sign detection unit 116 that, based on operation data D2 in which a state of a to-be-monitored facility 200 is acquired and a diagnostic model D3, determines presence or absence of an anomaly sign of the to-be-monitored facility 200, and generates anomaly sign alert data D6 indicating an occurrence of an anomaly sign when a determination result is positive (D5="1"); and a model update control unit 120 that, based on the operation data D2 corresponding to the anomaly sign alert data D6, determines whether or not the anomaly sign alert data D6 is reliable and, based on a result of the determination, determines the necessity of update of the diagnostic model D3.SELECTED DRAWING: Figure 1 【課題】異常予兆診断装置において、診断モデルの更新の要否を適切に判定できるようにする。【解決手段】監視対象設備２００の状態を取得した稼働データＤ２と、診断モデルＤ３と、に基づいて、前記監視対象設備２００の異常予兆の有無を判定し、判定結果が肯定（Ｄ５＝"１"）である場合に、異常予兆の発生を示す異常予兆アラート・データＤ６を生成する予兆検知部１１６と、前記異常予兆アラート・データＤ６に対応する前記稼働データＤ２に基づいて、前記異常予兆アラート・データＤ６が信憑性を有するか否かを判定し、その判定結果に基づいて前記診断モデルＤ３の更新の要否を判定するモデル更新制御部１２０と、を異常予兆診断装置１００に設けた。【選択図】図１
