Crewcut - a Tool for Modeling the Effects of High Workload on Human Performance

Abstract

The underlying problem that this work addresses is the incidence of high crew workload in modern systems. The specific problem is that the analysis and prediction of workload during system or procedure design currently involves either 1) the use of human subjects that is very resource consuming or 2) the use of subjective evaluations that are of questionable validity. The innovation we propose is to use computer modeling to predict crew workload. Techniques and supporting technologies are being developed by NASA and the U.S. Department of Defense that are applicable to many types of systems. The tools we will discuss address this problem by providing a sophisticated environment for the analysis of crew workload as well as evaluating the effects of high workload on ensuing human performance.
