Development Of Design Requirements For A Cognitive Assistant In Space Missions Beyond Low Earth Orbit, Güliz Tokadl, Michael C. Dorneich 2017 Iowa State University

Development Of Design Requirements For A Cognitive Assistant In Space Missions Beyond Low Earth Orbit, Güliz Tokadl, Michael C. Dorneich

Industrial and Manufacturing Systems Engineering Publications

This study describes the development of requirements for a cognitive assistant (CA) for use onboard a space vehicle/station. For missions beyond low Earth orbit (LEO), delayed communication will limit mission control’s ability to support the space crew in real time. During off-nominal situations, where no procedures have been developed prior to missions, crews must develop responses in real time and may increasingly rely on automation. A systematic approach was used to model the domain knowledge of the collaborative decision-making process of current space operations, extrapolate to missions beyond LEO, and develop the design requirements for a CA.
