A control apparatus monitors an amount of time that has elapsed since an article was stored at a first storage position or an amount of positional misalignment from a reference position of the article stored at the first storage position. This amount of time is a monitoring target amount, and the control apparatus monitors the monitoring target amount for each of multiple storage sections and causes a conveying apparatus to execute correction processing with a storage section in which the monitoring target amount has exceeded the set threshold as a target storage section. Correction processing is used for correcting the position of only the target article stored at a first storage position in a target storage section relative to a reference position.
