Impacting System Design with Human Performance Modeling and Experiment: Another Success Story

Abstract

In this study, task-network models using the Improved Performance Research Integration Tool were built to predict the mental workload and performance of the crew of a conceptual mounted combat vehicle. The modeling project analyzed which crewmember, if any, should be allocated the functions of controlling robotic assets in addition to standard mission functions similar to present tank crew missions. In order to further investigate issues derived from the modeling project and to verify its analytical results, a simulation experiment was conducted to examine the mental workload and performance of the combined position of robotics operator and gunner. The results of this experiment were consistent with the predictions generated by the modeling analysis. The modeling and experimental data have successfully contributed to modifications in the design concept for the modeled platform as well as its crewmember function allocations.
