Thought Questions

Open Ended Problems

1. We often face the challenge of making decisions when the information is noisy.  Discuss how we determine the "real" trend from noisy data when making the following decisions.  



a.  What is the rate of global warming?

b.  Has inflation reached an undesirable level in the national economy?
c.  Am I gaining weight?











Some complex sensors, typically analyzers, fail more frequently than the reliable temperature or pressure sensors.  Design some reliability checks that could be performed before every controller execution to prevent feedback based on an unreliable measured value.

This will improve safety and reliability of the process.
