Human-in-the-Loop Configurations in Process and Energy Industries: A Systematic Review

The human-in-the-loop performance evaluation is an area of growing interest in industries where safety-critical systems are in place. Concerns here are due to the increasing complexity of automation, new technologies for control, and safety. Because, unlike a more traditional approach to evaluating the human and the system they work with, human-in-the-loop gives a holistic view of their interaction (human, automation or artificial intelligence) and dynamics. It also emphasizes adapting the technology or automation to the human, being central, considering certain factors like risk. Therefore, there is a need to identify the relevant factors, novel measures and methods or improvements on existing methods that can be adapted for this field of research. This paper intends to present an overview of human-in-the-loop in the process and energy industries by presenting a literature summary highlighting current factors and measures, methods, gaps, solutions and future work. Experimental (13) and observational (11) studies have been reviewed for results. It was observed that new factors, measures and techniques are currently being explored to fill some of the current gaps for the human-in-the-loop, for example, during performance assessment new methods and modalities have been adopted such as eye tracking and electroencephalography methods. The results and open questions from the papers reviewed and possible future research opportunities are presented and discussed in this paper.
