ASM Alarm System Performance Benchmarking• Performed a Best-subsets (i.e., multivariate) regression forOverall Average Alarm Rate with 14 metrics (out of the morethan 30 collected)• The resulting multivariate regression model accounted foronly ~50% of the variance in the data• The factors considered significant were:– Degree of rationalization (negative coefficient)– Frequency of monitoring average alarm rate (positivecoefficient; a surprising result)– Degree of control sophistication (negative coefficient)– Frequency of monitoring worst actors (negative coefficient)– Average number of standing alarms (positive coefficient)There is no single “Silver Bullet” to alarm system performance14
