PROBLEM TO BE SOLVED: To provide a sensor assignment device capable of easily assigning a sensor to a diagnostic model, and a sensor diagnostic device.SOLUTION: A sensor assignment device according to one embodiment comprises: a measurement value storage part; a creation part; a calculation part; and a selection part. The measurement value storage part stores measurement values of plural sensors. The creation part creates plural sets of the sensor and argument, by assigning the sensor to each argument of a sensor diagnostic function having plural arguments. The calculation part calculates an evaluation value based on the value of the diagnostic function which is obtained by calculating with substitution of the measurement value stored in the measurement value storage part, for every set created by the creation part. The selection part selects at least one set from the plural sets, on the basis of the evaluation value of each set, calculated by the calculation part. 【課題】診断モデルに対してセンサを容易に割当てることができるセンサ割当て装置及びセンサ診断装置を提供する。【解決手段】一実施形態に係るセンサ割当て装置は、計測値記憶部と、生成部と、算出部と、選択部とを備える。計測値記憶部は、複数のセンサの計測値を記憶する。生成部は、複数の引数を有するセンサの診断関数の各引数に対して、センサを割当て、引数とセンサとの組合せを複数生成する。算出部は、生成部により生成された複数の組合せの各々について、計測値記憶部に記憶された計測値を代入して計算される診断関数の値に基づき評価値を算出する。選択部は、算出部により算出された各組合せの評価値に基づいて、複数の組合せの中から少なくとも１つの組合せを選択する。【選択図】図１
