Extraction of the Strategy for Plant Inspection Planning Based on Behavior Comparison of Experts and Novices

Abstract

In the patrol inspection of plants, experts find out more symptoms of anomalies than novices. However, experts are aging and many of them are going to retire in a decade. Novices and robots cannot replace experts easily because it remains unclear that how experts act differently to novices and why they do so. This study presents a method for elucidating the behavior differences between experts and novices by recording inspections of experts and novices to check the behavior differences from two perspectives: inspected objects and inspection methods. The behavior differences are shown to the experts and the novices to clarify why they take such actions. Finally, we try to extract the points that experts focus on and strategy that experts use for inspection planning considering the behavior differences and the reason of the actions. This paper also presents a case study using the method, which revealed 7 distinctive behavior differences that reflects inspection planning strategies of the expert. According to the case study, experts are conscious of potential risk of each device, quality of the information they gain, time efficiency of the inspection, and development of their five senses, in general.
