摘要：According to an embodiment, an operation apparatus includes a featurewaveform extraction unit (13) which extracts a feature waveform before and after achange time point at which the operating state of an instrument changes. The operationapparatus includes an operation unit (14) which performs an operation for decomposingfeature waveforms into one or more frequency components. The operation apparatusincludes an instrument feature database unit (15) which stores frequency featuresrepresenting operating states of a predetermined instrument. The operation apparatusincludes a harmonic weighted-distance calculator (16) which calculates a weighteddistance, on polar coordinates, between an operation result and a feature stored in theinstrument feature database unit (15), the weighted distance being calculated for eachoperating state. The operation apparatus includes an operating state estimation unit (17)which estimates operating states of an instrument, based on the weighted distance.
