A Comparison Study of Inspector's Performance between Regular and Complex Tasks
This research was to study a comparison of inspector’s performance between regular and complex visual inspection task. Visual task was simulated on DVD read control circuit. Inspection task was performed by using computer. Subjects were 10 undergraduate randomly selected and test for 20/20. Then, subjects were divided into two groups, five for regular inspection (control group) and five for complex inspection (treatment group) tasks. Result was showed that performance on regular and complex inspectors was significantly difference at the level of 0.05. Inspector performance on regular inspection was showed high percentage on defects detected by using equal time to complex inspection. This would be indicated that inspector performance was affected by visual inspection task. Keywords—Visual inspection task, Regular and complex task.

Evaluation of different training strategies to improve decision-making performance in inspection
Various studies in inspection have demonstrated the usefulness of feedforward (FF) and feedback (FB) in improving the performance of inspectors. However, the results of these studies are not conclusive as to their effect on the sensitivity and response strategy of inspectors. Hence, this study evaluates the individual and collective effect of FF and FB on the sensitivity and response strategy of the inspectors using a computer simulation of a contact lens inspection task. Twenty-four subjects, randomly assigned to various conditions, performed an inspection task wherein the FF and FB conditions were manipulated between the subjects. In addition, the defect probability and the discriminability were manipulated within the subjects. Subsequently, the results were interpreted using signal detection theory. Although feedback improved the sensitivity, a finding consistent with earlier studies, feedforward was more effective in assisting the inspectors in setting their response strategy closer to the optimum. Moreover, providing both FF and FB resulted in improved sensitivity as well as a more optimal response strategy. © 1996 John Wiley & Sons, Inc.
