Smarter SCADA Alarming

One afternoon at a waste water treatment facility, an alarm goes off when the water pressure gets too high in one of the tanks. The alarm is set at priority level 4, which means “critical,” but it doesn’t stand out because almost every other alarm at the facility is set at that level. Besides, the operator can’t acknowledge it right away because he’s dealing with several other alarms that went off a few minutes earlier – which he doesn’t yet realize are just “nuisance alarms.”
