PROBLEM TO BE SOLVED: To provide a dynamic state monitoring device and the like which presents detailed information with respect to the dynamic state of a machine plant to a user.SOLUTION: A dynamic state monitoring device 1 comprises: time series data acquisition means which acquires time series data including detection value of a sensor; a data mining learning unit 161 which learns a normal model indicating a normal range of a feature vector; an anomaly measure calculation unit 162c which calculates an anomaly measure indicating an abnormality degree of the feature vector on the basis of the normal model; and display control means in which a plurality of scatter charts by combination of two sensors among a plurality of sensors is displayed in a matrix form. The display control means displays a mark corresponding to size of the anomaly measure at a position corresponding to the detection values of two sensors in each of the scatter charts to create the plurality of scatter charts.SELECTED DRAWING: Figure 4 【課題】機械設備の動態に関するきめ細かな情報をユーザに提示する動態監視装置等を提供する。【解決手段】動態監視装置１は、センサの検出値を含む時系列データを取得する時系列データ取得手段と、特徴ベクトルの正常範囲を示す正常モデルを学習するデータマイニング学習部１６１と、正常モデルに基づいて、特徴ベクトルの異常度合いを示す異常測度を算出する異常測度算出部１６２ｃと、複数のセンサのうち、二つのセンサの組合せからなる複数の散布図を行列形式で配置して表示する表示制御手段と、を備え、表示制御手段は、それぞれの散布図において二つのセンサの検出値に対応する位置に、異常測度の大きさに対応する印を表示することで複数の散布図を作成する。【選択図】図４
