Analysis of Per-Item and Per-Lot Paced Visual Inspection for High Target Probability Conditions

Abstract

Inspection, a necessary component in manufacturing to ensure process and quality control, has two main components, visual search and decision-making. The human element, while not perfect, cannot be eliminated from the inspection process because of the inherent advantages that a human inspector has to offer. Since some type of pacing is generally incorporated into the manufacturing setting for cost effectiveness, discovering how speed and rigidity affect the accuracy of inspection is essential. Therefore, this study attempts to explore the relationship between time limits imposed on inspectors and the amount of flexibility they have in performing the inspection task.
