Retracted: Economic Benefit Analysis of Process Control for Predominantly Transient Processes

The question of how to assess the monetary value of process control has been of significant interest from both the academic and industrial points of view since the inception of the field. While metrics exist for addressing this problem in the case of predominantly steady-state processes, no work has been reported for predominantly transient processes. In this paper, we develop two performance metrics that allow the evaluation of the monetary value of improving process control for predominantly transient processes. We demonstrate the utility of the metrics in assessing (1) whether improvement of process control would yield any worthwhile monetary benefits, and (2) for control structures that carry out multiple production transitions within a production schedule, the specific areas where improvement of process control would yield the highest economic benefits.
