The MIDAS 4.0 application is the first of a multi-year effort that seeks to develop a human performance model-based design and evaluation tool to be used to determine if emerging technologies, CONOPS, and procedures support multi-agent Situation Awareness. The approach is to provide a theory-based, computational model that supports quantitative SA predictions. The first year of this project modeled the flight deck and the ATC operators in the system, and contained a number of model interactions, contingencies, and dependencies among these system operators. The modeling effort that used MIDAS 4.0 resulted in the development of a long term working memory model that was driven by the bandwidth and the operator workload. This augmentation to the MIDAS code base resulted in improving the SA model’s performance and set the stage for the MIDAS 5.0 implementation of Wickens’ Salience, Effort, Expectancy and Value (SEEV) models of attention.
The MIDAS 4.0 proof-of-concept simulation presented in the movie is of a Captain and Co-Pilot on the approach, descent, and land phase of flight to a generic airport. The flight crew is completing a number of baseline activities that are required for safely landing the aircraft on the runway. This baseline MIDAS model was augmented in the next application with the integration of the SEEV model into MIDAS, which resulted in MIDAS 5.0.
