PRODUCTION SYSTEM, PRODUCTION LINE ANALYSIS METHOD, LEARNING DEVICE, INFERENCE DEVICE, LEARNED MODEL, AND LEARNED MODEL GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/233745
Kind Code:
A1
Abstract:
The present invention comprises: a key performance indicator calculation unit that calculates, on the basis of device data related to a production history of each production device (101), a value of a key performance indicator which is a criterion for determining whether the operation state of a production line (20) is acceptable; and a stop factor calculation unit (302) that calculates, on the basis of device data including the device state of each production device (101), a value of a plurality of stop factors which affect a decrease in the key performance indicator. The stop factor calculation unit (302): calculates the value of the key performance indicator and the value of the stop factors as values per unit time with respect to values of the same type and of the same time in relation to production on the production line (20); and calculates the value of a non-summed stop factor for which the value of the stop factors has not been calculated on the basis of the device data including the device state of each production device (101). An operator can quantitatively ascertain what is the cause of a decrease in the key performance indicator, and to what degree this cause affects a decrease in a production KPI.
