Maintenance on manufacturing equipment is categorized into periodic maintenance (PM) and breakdown maintenance (BM).
Usually, PM is performed more frequently (conservatively) than the actual occurrences of breakdowns.
BM aims to resolve an unpredicted or unexpected breakdown and may have a greater effect than PM on the schedule or yield rate of the manufacturing process. Especially if the process is of a serial type, a breakdown on a particular piece of equipment may result in the halting of the entire process.

- The causal factors of processing faults are determined in real time.
- Abnormal operation patterns are detected on the basis of the already learned normal operation patterns.
