EXPERTUNE (2004) Establishing a Basis for Performance

To get a useful historical perspective from performance monitoring, several key items must be
established. Loop health must be defined in terms of performance metrics and then a method for
combining these metrics in a useful way must be set up.
The first step is for the plant to choose the metrics that will make up loop health. This may vary
somewhat depending on the loop type. Once these metrics are chosen, a method for combining the
metrics to arrive at a single health number must be decided. This method defines the baseline of
performance for every loop. Different categories of loops will have a different basis for performance.
For example, flow temperature, pressure, and level may all have a different basis of performance. Also
the plant may want the basis of performance to be based on historical metrics or a time when the plant
was running well.
