The Society of Automotive Engineers (SAE) International has determined that a conference paper based on a recent collaborative effort between Ames Intelligent Systems Division (Code TI) and Human Systems Integration Division (Code TH) collaborators is “among the most outstanding SAE Technical Papers of 2008,” and will be published in the first (April 2009) volume of SAE International Journal of Aerospace.
The paper, titled “Operator Performance Evaluation of Fault Management Interfaces for Next-Generation Spacecraft,” reports an empirical study evaluating two Advanced Caution And Warning Systems (ACAWS) concepts for off-nominal situation management on next-generation spacecraft, one incorporating a relatively low level of automation, the other a relatively high level. The results showed that the more highly automated concept produced both more accurate fault diagnoses and faster fault resolution times, with lower workload and no loss of situation awareness. Armed with this information, designers can make more informed decisions concerning the proper balance between automation-related operational enhancements and the associated costs of software development and increased onboard computing requirements.
Authors of the paper were Miwa Hayashi, Ujwala Ravinder, Brent Beutter, Robert McCann, Lilly Spirkovska, and Fritz Renema.
