Assignee: NEC CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 16:
17. A non-transitory computer-readable storage medium storing a program executable by an information processing apparatus to:
identify a predetermined time width in which the time-series data matches a specified label;
divide the time-series data in the predetermined time width in which the time-series data matches the specified label by a shorter time width than the predetermined time width to generate a plurality of division time-series data;
classify, by using a generator, a state of each of the plurality of division time-series data as anomalous or non-anomalous, by:
calculating a similarity degree between each of the division time-series data and each a plurality of pre-classified division time series data;
assigning the state of each of the division time-series data as anomalous or non-anomalous in accordance with the pre-classified division time series with which the each of the division time-series data has a highest similarity degree; and

for each of the plurality of division time-series data of which the state has been classified as anomalous, determine that the manufacturing facility is in an anomalous state in a corresponding time width,
wherein division of the time-series data to generate the plurality of division time-seris data provides for increased accuracy in detecting that the manufacturing facility is in the anomalous state.
