Conduct Simulations to Assess Human Performance and Workloads

HSI simulations identify the plausible outcomes of specific design assumptions and performance parameters (e.g., workload, high driver tasks). The simulation is critical in early stages of system development since it enables the analyst to assess alternate design approaches without committing resources or losing design decisions.

The interactive nature of task network simulation affords the HSI analyst the flexibility to tailor the configuration of task sequences and operator assignments to realistically model system operations. This simulation provides the analyst with a transcript of task completion status and operator availability for additional tasks as well as a summary of workload distributions by operator and task. These data can be used by system designers to evaluate, predict and identify: 1) system manning level requirements; 2) training and cross-training requirements; 3) critical task sequences; 4) critical nodes; 5) reiterative task sequences; 6) minimum, median and maximum task completion times; 7) redundant and/or unnecessary task sequences; 8) critical personnel; 9) overextended resources/personnel; and, 10) underutilized personnel and personnel resources.

HSI simulation addresses the verification of design approaches and function allocations. Simulations involve modeling of functional and task sequences for individual operators/maintainers and for crews. The simulation receives input from the role of the human and the task analysis.
