Analysis and Modeling of Information Handling Tasks in Supervisory Control of Advanced Aircraft.

摘要

The problems addressed in this study stem from the increasing supervisory loads imposed on the operator in airborne system operations. Future aircraft will be characterized by high information loads, several time constraints, and complex decisions regarding allocation of operator's attention, as well as display resources. The information costs and the limited processing capabilities of the human operator makes it necessary to optimize the information selected, processed, and displayed. Techniques for information selection were developed based on multi-attribute utility models and queueing formulations. These techniques take into account both subjective, individual preference factors and needs of the operator. An experiment was conducted based on a computer-aided, multi-task airborne information-handling situation with different aiding and demand levels. Model-based recommendations led toward superior performance, both in low and high stress situations. The techniques provided an analytic framework that was helpful in identifying the individual operator's information handling strategies. These techniques are expected to be useful in specifying needs and for training operators or systems to efficiently perform information handling tasks. (Author)
