PROBLEM TO BE SOLVED: To provide a management apparatus capable of identifying whether an abnormality results from a sensor or the other device if the abnormality occurs to a plant or system including a sensor.SOLUTION: A management apparatus 10 includes: a first calculation unit 101; and an abnormality determination unit 102. The first calculation unit calculates a second physical quantity indicating a state of an observation target on the basis of a first physical quantity that is a physical quantity relating to the observation target. The abnormality determination unit determined whether a first sensor 30 is abnormal on the basis of comparison of the second physical quantity measured by the first sensor 30 with the second physical quantity calculated by the first calculation unit 101. 【課題】センサを備えるプラントやシステムで異常が発生した場合、その異常がセンサに起因するのかその他に起因するのかを特定することができる管理装置を提供する。【解決手段】管理装置１０は、第一の算出部１０１と、異常判定部１０２とを備える。前記第一の算出部は、観測対象に係る物理量である第一の物理量に基づいて、前記観測対象の状態を示す第二の物理量を算出する。前記異常判定部は、第一のセンサ３０が計測する前記第二の物理量と前記第一の算出部が算出した第二の物理量との比較に基づいて、前記第一のセンサが異常であるか否かを判定する。【選択図】図１
