Abstract: A Family of Systems (FoS) is being developed that will comprise the Armys Future Combat Systems (FCS). In an effort to determine the most effective and efficient way to integrate the diverse but related new systems within the future force, the U.S. Army Research Laboratory is developing an operator workload model of FCS FoS operations. This development is part of the Human Robotics Interaction Army Technology Objective in which Soldier workload models of individual systems are being developed with the intent of integrating them into one all-encompassing model. This Improved Performance Integration Research Tool (IMPRINT) model will enable the investigation of individual to overall workload and will examine how these Soldier-systems can effectively combine their efforts to more efficiently accomplish a mission. FCS FoS will rely heavily on unmanned systems such as unmanned ground vehicles and unmanned aerial vehicles (UAVs) to assume such roles as intelligence gatherer, perimeter security, vehicle reconnaissance, reconnaissance and surveillance for initial entry forces, call for fire, battle damage assessment, etc. In fact, at least 11 types of UAVs were committed to Operation Iraqi Freedom, demonstrating the current need for the capabilities that UAVs can provide. In order to understand the combination of the capabilities of a UAV with other system capabilities within a commanders arsenal, a model of operator workload was developed for the Raven small UAV (SUAV). This project describes the detailed task analysis used to build an IMPRINT model and the initial model runs for determining the workload associated with operating the Raven SUAV with a two-person team.
