An Approach for Improving Alarm Prioritization Analysis.
Abstract:
A new function-based approach for alarm prioritization is proposed that has significant
advantages over the traditional annunciation methods. In this new approach, alarms are
considered to be health indicators of a plant function. Instead of individually prioritizing
each alarm, the function-based approach identifies the importance, to the plant, of the
loss of each plant function. Alarms associated with each function then inherit the
function's priority in the plant's operation.
This paper outlines the opportunity for enhancements to current alarm prioritization
approaches, discusses the basis for organization of plant functions, describes the
proposed prioritization approach, and summarizes advantages and our initial experience.
In addition, the application of common off-the-shelf database technology, used to provide
a design environment for supporting this approach, is described.
