Root-cause analysis

“Why did Line 2 stop three times last week?”

Root-cause analysis correlates events across MES, quality, maintenance and process data to trace a stoppage or defect back to the change that actually caused it.

Questions it answers

“Why did Line 2 stop three times last week?”

“Which upstream change is behind this scrap spike?”

“Are these two defects really the same problem?”

How it works

1.
Aligns stoppages, alarms, quality events and process changes on a shared timeline.
2.
Ranks candidate causes by correlation strength and recurrence.
3.
Lets engineers drill from a symptom to the signal and shift where it started.

Outcomes
