Crew Workload Assessment. Development of a Measure of Operator Workload.

摘要

The study objective was to develop a quantitative measure of workload useful in crewstation evaluation. Flight tasks of varying difficulty were simulated, and 35 pilot response variables analyzed. Selected physiological and visual response variable were applied in a stepwise regression procedure to the prediction of a composite performance/opinion measure, which reflected differing levels of task difficulty. The resulting linear equation was reformulated as a preliminary operationally-defined measure of information-processing workload. (Author)
