Overall Controller Effectiveness (OCE) Calculator

How much can you profit from improving controller performance?

While manufacturers invest millions in control infrastructure, few quantify the relative performance of those investments and fewer achieve suitable ROI.

Like OEE, Overall Controller Effectiveness (OCE) is a composite metric for objectively evaluating PID control loop performance. OCE considers how often a facility’s controllers operate: in automatic, within acceptable error, and without physical constraints.

We’ve benchmarked over 150 production facilities and tens of thousands of PIDs using OCE. Our OCE Calculator shows how your facility’s performance compares – and how much more there is to gain from optimization. Enter your data below to see.

Distributions for OCE and the associated metric inputs are based on statistical analysis of PID loops from more than 150 production facilities. Potential savings are calculated at 65% of a typical investment of $10,000 per PID control loop (i.e., hardware, software, implementation, etc.). Likely savings is estimated at 60% of the potential savings achieved within six (6) months based on historical performance.
