Task Analysis of the UH-60 Mission and Decision Rules for Developing a UH-60 Workload Prediction Model. Volume 4. Segment Decision Rules Appendixes H and I
Abstract
A composite scenario was used to conduct a comprehensive task analysis of the UH-60 helicopter mission. This analysis used a top-down approach to identify the phases, functions, and tasks of the mission. Nine phases, 34 segments, 48 functions, and 138 tasks were identified. The crew-member performing each function was identified, and estimates of the sensory, cognitive, and psychomotor workload associated with the tasks were derived. Estimates of the task times also were derived. The mission/task analysis data were used to develop a computer model of workload for UH-60 crewmembers. The model used a bottom-up approach to build mission functions from tasks and mission segments from functions. Decision rules were written to specify the procedure for combining the tasks into functions and the functions into segments. The model permitted an analysis of total workload experienced by each crewmember in the performance of both sequential and concurrent tasks. Keywords: Man-machine interface.
