This Month's Tip : Simple KIPs for Alarm Management

The following key performance indicators (KPI) are used by EEMUA (Engineering Equipment and Materials Users Association) to measure system performance.

  1. Average alarm rate

    This is the total number of alarms sent to the operator during the period of the analysis, divided by the time range covered by the data. EEMUA suggests that an average alarm rate of 1 alarm per 5 minutes is "manageable", while a rate of less than 1 alarm per 10 minutes is "very likely to be acceptable".

  2. Maximum alarm rate

    This is the worst case load during any ten minute period. It is calculated by splitting the alarm journal into consecutive ten minute time slices and taking the maximum. EEMUA suggests that in a 10 minute interval following a major plant upset, having less than 10 alarms is "manageable", but having more than 20 alarms is "hard to

  3. Percentage of time during which alarm rates are outside acceptability target

    This is the proportion of the time that the alarm system is outside the alarm rate target. EEMUA suggests that a rate exceeding 1 alarm per 2 minutes (or 30 alarms per hour) is "over-demanding".
