To estimate an anomaly cause of equipment simply and highly accurately.SOLUTION: An anomaly cause estimation device 1 includes: a measurement value input unit 2 that inputs a measurement value obtained from a sensor provided in equipment; an anomaly determination unit 4 that determines presence or absence of an anomaly of the measurement value; an anomaly cause estimation unit 6 that estimates an anomaly cause of the equipment by inputting the presence or absence of the anomaly of the measurement value to an anomaly event model selected from a set of anomaly event models divided in advance based on an anomaly event assumed in the equipment; and a result output unit 9 that outputs an estimation result of the anomaly cause.SELECTED DRAWING: Figure 1 【課題】設備の異常原因を簡便かつ高精度に推定する。【解決手段】異常原因推定装置１は、設備に設けられたセンサから得られる計測値を入力する計測値入力部２と、計測値の異常の有無を判定する異常判定部４と、設備で想定される異常事象に基づいて予め分割された異常事象モデルを選択したものに、この計測値の異常の有無を入力して、設備の異常原因を推定する異常原因推定部６と、異常原因の推定結果を出力する結果出力部９とを有する。【選択図】図１
