Abstract:

In operating industrial facilities, alarm systems are configured to notify operators about any abnormal situation. The industrial standards (EEMUA and ISA) suggest that on average an operator should not receive more than six alarms per hour. This is, however, rarely the case in practice as the number of alarms each operator receives is far more than the standard.

There exist strong industrial needs and economic benefits for better interpreting and managing the alarms, and redesigning the alarm systems to reduce false and nuisance alarms, and increase the alarm accuracy. In this talk, we plan to summarize our recent work in this new area, targeting a quantitative and data based approach, called “alarm analytics,” and presenting a new set of tools for alarm visualization, performance evaluation and analysis, and rationalization design, thereby to help industrial processes to comply with the new standards. Topics to be discussed include

• How to present alarm information from a unit/plant/area?

• How to quantify and improve alarm accuracy and alarm chattering?

• How to study and cluster historical alarm floods?

• How to capture connectivity and causality from process and alarm data?

• What is recent development on advanced alarm monitoring?

The tools have been tested with real industrial data and used by process engineers in Canada and elsewhere.
