A REAL-TIME NAVAL OPERATOR WORKLOAD ESTIMATION SYSTEM

THE OBJECTIVES OF PHASE I OF THIS PROJECT ARE TO (1) SELECT A WORKLOADMODELING APPROACH THAT IS APPROPRIATE FOR ESTIMATING NAVAL OPERATOR WORKLOAD IN REAL-TIME, (2) SPECIFY A REAL-TIME NAVAL OPERATOR WORKLOADESTIMATION SYSTEM BASED ON THE SELECTED WORKLOAD MODELING APPROACH, AND (3) INVESTIGATE WAYS IN WHICH THE WORKLOAD MODELING APPROACH OR THE WORKLOAD ESTIMATION SYSTEM CAN BE GENERALIZED TO APPLY TO OTHER SITUATIONS AND OPERTORS. IN PHASE II, THE SPECIFIED SYSTEMS WILL BE DEMONSTRATED, AND THE DESIRABILITY AND FEASIBILITY OF GENERALIZING THESYSTEM FOR OTHER APPLICATIONS WILL BE DECIDED. THE SYSTEM SPECIFIED IN THIS PROJECT WILL BE BASED ON WORKLOAD MODELING APPROACHES THAT HAVE BEEN PROVEN EFFECTIVE IN ESTIMATING OPERATOR WORKLOAD IN COMPLEX CONTROL SITUATIONS. MODIFICATIONS AND ENHANCEMENTS IN THESE APPROACHES WILL HAVE BEEN MADE AS NECESSARY TO PROVIDE THAT THE SYSTEMEFFECTIVELY ESTIMATES NAVAL OPERATOR WORKLOAD DURING TIMES OF TACTICALDECISION MAKING. THIS INFORMATION CAN BE USED TO PREDICT IMPENDING PERIODS OF OPERATOR WORK OVERLOAD SO THAT ACTIONS CAN BE TAKEN TO REDUCE THE OPERATOR'S WORKLOAD TO MAINTAIN MISSION CAPABILITIES AND SYSTEM PERFORMANCE.
