Abstract: An anomaly determination method, in a production management system that manages a production line including first, second, and third production devices, includes: obtaining, from among first, second, and third operating status data of the first, second, and third production devices, respectively, at least the first and third operating status data; when it is determined that the second operating status data was not obtained, predicting a dummy operation timepoint corresponding to a planned production quantity of the second production device, and generating dummy operating status data including the planned production quantity and the dummy operation timepoint; performing anomaly determination processing on production processes as a whole based on the first and third operating status data and the dummy operating status data; and outputting determination result information representing a result of the anomaly determination processing to display the determination result information on a display device included in the production management system.

Abstract: An information processing method includes: calculating a probability density distribution of a work time that is at least part of a setup time, based on production performance data read from storage, the setup time being time taken for a setup work that is performed between lots; determining whether the work time is anormal, based on the probability density distribution; and outputting a result of the determining.
