Maintenance teams still schedule work on fixed calendars, so a line goes down between scheduled checks as often as it doesn't. Remaining useful life gets estimated by experience, not by what the sensor data is actually saying.
AI reads the sensor data continuously. Predictive models estimate remaining useful life and flag a likely failure before it happens. Agents schedule the maintenance and the spare parts it needs, so the part is on hand when the work order is. Your line runs on a schedule that matches what the equipment is actually doing, running in your own environment.
