Setpoints for process parameters are usually established by a combination of worst-case calculations and engineering judgment. This approach does not provide any rational basis for establishing the probability of a system failure as a function of the setpoint. The probability approach for selecting setpoints presented here offers an informative, coherent method of addressing safety evaluations and safety decisions throughout an entire plant. Admittedly, determining the load, capacity and measurement means, and standard deviations as well as their probability distributions are formidable tasks. But the traditional methods of selecting setpoint values imply that all these tasks have been done by default. Actually doing these tasks and applying the method described here will provide probability estimates for use in an objective decision process.
