Countermeasure recommendation device and countermeasure recommendation method

A countermeasure recommendation device, comprising:

• a data acquisition unit configured to collect a plurality of pieces of facility data from a manufacturing facility, and assign a label to each piece of the facility data based on facility setting data, wherein each assigned label identifies a facility process, and wherein the facility setting data includes a required time for completion of the facility process;
• a countermeasure detection unit configured to, based on the facility data, create countermeasure record data including a type of a countermeasure performed on the manufacturing facility, a characteristic amount indicating an effect of the countermeasure, a time point at which the countermeasure is performed, and a countermeasure execution time, wherein the countermeasure detection unit is further configured to:
• acquire the facility data for a duration starting a predetermined amount of time before the time point and ending a predetermined amount of time after the time point,
• extract a blank period from the acquired facility data, wherein the blank period is a period in which the facility data has no value larger than a maximum value of the required time of the facility process,
• correct the time point of the countermeasure record data based to an end point of the extracted blank period;
• a countermeasure recommendation unit configured to calculate the characteristic amount from a predetermined number of latest facility data, extract the characteristic amount of the countermeasure record data similar to the calculated characteristic amount, and select the countermeasure related to the extracted characteristic amount;
• and
• a countermeasure presentation unit configured to present the countermeasure selected by the countermeasure recommendation unit in a visualized state.
