Reliability Analysis of Unpaced Visual Inspection Tasks.
Abstract
The research was directed toward application of classical hardware reliability analysis methods to describe human performance error rates on discrete tasks. The specific problem investigated was the mathematical formulation needed to describe the probability of human error associated with discrete unpaced, visual inspection tasks. Knowledge of the inspector's perception of the percentage defective, his ability to numerically express his perception, and the effect of a dynamic environment on each were several secondary objectives which impacted this research and which needed to be investigated. Ten subjects were laboratory tested, with the number of items to first error, items between errors, defects to first error, and defects between errors recorded. Through classical inference theory, the underlying distributions of errors were investigated. (Author Modified Abstract)
