Adults can learn a thing or two from children. That’s especially true when it comes to matters of time. Whereas adults view it as fashionable to show up to a social event 15 or more minutes late, children can’t wait to go and be a part of the action. When at a theme park adults typically their time strolling from place to place while children know that each minute of delay can cost hours longer in line. Simply put: When it comes to time every second matters. That viewpoint seems highly relevant to process control, control loop tuning, and calculating Dead-Time. Dead-Time is generally the model parameter that’s easiest to calculate when tuning a PID controller.

The latest report published by the Manufacturing Institute underscores the growing shortage of skilled labor here in the United States. Their 2014 study of skills and training Out of Inventory simply affirms what manufacturers knew coming out of the Great Recession. Years of trimming staff during the downturn would come at a cost during the upturn. Apparently the bell has sounded it’s time to go to class.
