Better operator alarms make money for YOUR plant by reducing operational variability, which contributes to a reduction in operating costs and, in cases where throughput is increased, to a reduction in the unit costs of production. The single biggest cause of poor operator alarm performance is the values at which the alarm limits are set. But search for advice on how to find correct alarm limits and the answer will be “put the limits at the boundary of where you normally operate”. For the practising engineer this advice is next to useless because he or she doesn’t have a way to locate that boundary across many hundreds of variables.

The key is an Operating Envelope or Operating Window spanning the many hundreds or even thousands of variables, some with alarms defined and some without.

In this webinar, first presented in February 2019, you will discover a simple visual method of locating the Operating Window and Envelope of any chosen set of objectives and of setting alarm limits around its boundary. You will see the usefulness of being able to see and compare Windows and Envelopes for different operating objectives and the benefits of predicting Alarm Performance with immediate feedback.
