Workload and Workload Measurement

Abstract

It has been stated for many years that workload is an important problem area for man-machine-systems research and development. In order to evaluate alternative solutions in systems design, it is often deemed necessary to measure not only system performance, but also human operator workload. However, there exist too many conflicting ideas about the definition and measurement of workload (see, e.g. (1), (2), (3), (4)). The term workload frequently is used even without any definition of what it is.
