      Feigh, Karen M.; Pritchett, Amy R. (Georgia Institute of Technology, 2006-09)
      This paper discusses designing support systems for cognitive work environments, focusing specifically on airline operations. Previous studies found that cognitive work, which includes activities such as judgment and decision ...
    • Design of Support Systems for Airline Operations 

      Feigh, Karen M.; Pritchett, Amy R. (Georgia Institute of Technology, 2006-05)
    • Design of Support Systems for Cognitive Work in Airline Operations 

      Feigh, Karen M.; Pritchett, Amy R. (Georgia Institute of Technology, 2006-09)
      This paper examines design of support systems for airline operations. Previous studies found that cognitive work which includes activities such as judgment and decision making varies with context such that a single method ...
    • Design of Support Systems for Dynamic Decision Making in Airline Operations 

      Feigh, Karen M.; Pritchett, Amy R. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers (IEEE), 2006-04)
      To date, there has been very little research conducted on the design of support systems for dynamic decisions environments, such as airline operations. The paper discusses the idea that the regulation of dynamic systems ...
