Glenn, Floyd A., Dick, A. O. and Bittner, Alvah C. (1987): Prediction of Personnel Requirements for System Operation. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 358-362.

“This paper presents the concept of an Automated Job Analysis Tool (AJAT) which predicts personnel characteristics that are required in order to ensure acceptable human-system performance with a specified system design. The scope of this tool is intended to be quite broad, applying to all types of military systems, addressing the performance of both operators and maintainers, providing a means for considering training issues, and incorporating the effects of all relevant performance-impacting factors. In order to achieve this objective, several major innovations in performance prediction technology are required; these are described in this paper in terms of AJAT requirements, current technology status, and a plan for developing and validating the required capabilities. The AJAT concept is based on the use of existing models (i.e., HOS, CAR, and possibly others) to predict performance under specified conditions and the use of a factor-analytic framework to achieve efficient mapping of the performance space of interest.”

Hill, Susan G., Plamondon, Brian D., Wierwille, Walter W., Lysaght, Robert J., Dick, A. O. and Bittner, Alvah C. (1987): Analytic Techniques for the Assessment of Operator Workload. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 368-372.

“Workload techniques may be divided into two broad classes: 1) Analytic techniques -- predictive techniques that may be applied early in system design before "operator-in-the-loop" studies; and 2) Empirical techniques -- workload measurements taken with "operator-in-the-loop" during simulator, prototype, or system evaluations. Described here are five categories of the analytic techniques: 1) Comparability Analysis; 2) Mathematical Models; 3) Expert Opinion; 4) Task Analytic Methods; and 5) Simulation Models. A description, with examples, is given for each category. The motivation for focusing on the analytic techniques lies in their application during the earliest stages of system development where the greatest design flexibility is available at the least cost.”
