Analysis and Modeling of Information Handling Tasks in Supervisory Control of Advanced Aircraft.
Abstract
This report describes research and development centered on evaluation of information needs and automated management of information displays in advanced aircraft operations. Techniques for information selection were developed based on Multi-Attribute Utility (MAU) models and queueing theory formulations. These techniques take into account both subjective factors and objective situational conditions, as well as the immediate information monitoring and control needs of the operator and the impact on other unattended processes. The combined MAU/queueing model was tested in a Monte Carlo simulation. The experiment compared performance of the MAU-based policy to other priority policies both in event selection and information source selection. Initial results suggest that the value-based model is suitable for concurrent evaluation of information source and event sequence. The information management concept based on the MAU model seems to be superior to those based on traditional priority assignment. Possible applications of the approaches and the plan for further validation are also discussed. (Author)
