The Department of Defense’s vision of network centric operations will likely bring about higher operator mental workload due to the large volume of incoming information. As a result, it is critical that systems designers develop predictive models of both human and system performance, such that they can determine how a proposed technology will influence not only operator workload, but also system performance. To this end, this paper introduces a discrete event simulation approach to human-system modeling that includes a quantitative relationship between workload and performance, inspired by the Yerkes-Dodson relationship. Using the concept of utilization, or operator percent busy time, as a surrogate workload measure, we demonstrate that a quantitative instantiation of an inverted-U workloadperformance curve improves discrete event simulation model predictions in a human supervisory control model of single operator control of multiple unmanned vehicles. While this work generates the first known empirical evidence of a parabolic workload-performance as a variable in a quantitative predictive human performance model, this effort is preliminary and future research implications are discussed.

Extreme environments are characterized as those situations which place a high demand on the physiological, affective, cognitive, and/or social processing resources of the individual. Extreme environments strongly perturb the body and mind, which in turn initiate complex cognitive and affective response strategies. Different types of extreme environments may share some aspects but can also have unique demand characteristics. For example, exposure to the cold and isolated environment of an Antarctic expedition may result in extreme social and sensory deprivation, whereas exposure to military combat operations may entail extreme sensory overload. It is clear that there are many different types of extreme environments or situations, but it is less clear that an individual’s cognitive and affective responses are as varied as the different types of extreme environments.
