A fuzzy model for workload assessment in complex task situations

A method for combining subjective measures of workload and task characteristics is described. Data describing the human operator performance in compensatory tracking tasks at three levels of task complexities are used to develop a distribution function of fuzzy workload. The Cooper-Harper (CH) subjective judgment of task difficulty is administered to the subjects after each task completion. The final results show the relationships between fuzzy workload distribution as a function of task complexity.
