ItemModeling Cockpit Interface Usage During Lunar Landing Redesignation(Georgia Institute of Technology, 2009) Chua, Zarrin K. ; Major, Laura M. ; Feigh, Karen M.Fulfilling NASA's space exploration objectives requires precision landing to reach lunar sites of interest. During the approach and landing stages, a landing point redesignation (LPR) display will provide information to the crew regarding the characteristics of alternate touchdown points. Building on a previous study which examined crew tasks during LPR but did not account for the specialized behavior of experts, this investigation will present a new task sequence model, specific to expert decision-making. This analysis furthers the development of a predictive task execution model, which is used to test the efficacy of alternate information display and operator actuator design concepts. The task model and cockpit display recommendations presented in this study provide a significant improvement in LPR task execution time. This paper examines the task sequence during lunar landing, describes the predictive task execution process model, and recommends cockpit display requirements for effective decision making.

ItemAirline Command and Control: An Ethnographic Study(Georgia Institute of Technology, 2007) Feigh, Karen M. ; Pritchett, Amy R.The role of airline operations control centers in the national air transportation system is increasing. Yet, the role of airline operations personnel has not been well studied. This paper presents the findings of a series of ethnographic studies examining the work of airline Operational Managers (OMs) across several major and regional airlines. The role of airline OMs, and the information and tools they use to solve problems and maintain the airline's published schedule are discussed. Additionally, several work models developed as a result of the ethnography are presented and discussed. The work models include an information flow model, cultural model, artifact models, and sequence models. Implications are presented and discussed which transcend airline operations and are applicable to command and control more generally.

ItemDesign of Support Systems for Cognitive Work in Airline Operations(Georgia Institute of Technology, 2006-09) Feigh, Karen M. ; Pritchett, Amy R.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 of supporting cognitive work can not apply in many situations. Specifically, time constraints have been found to be a major factor in the both the decision strategies adopted by individuals and in the contextual control mode individuals operate in. An approach is presented to incorporate the Contextual Control Model into the design of a cognitive work support system to address the issue of varied time constraints. Specific examples are given for support systems for airline decision makers operating in the Strategic, Tactical and Opportunistic Contextual Control Modes.

ItemDesign of Multi-mode Support Systems for Airline Operations(Georgia Institute of Technology, 2006-09) Feigh, Karen M. ; Pritchett, Amy R.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 making, varies with context such that a single method of supporting cognitive work would not apply in many situations. For example, time constraints have been found to be a major factor in the both the decision strategies adopted by individuals and in the contextual control mode individuals operate in. In order to best support multiple modes of cognitive work, a multiple mode support system design is proposed. The Contextual Control Model is used as the basis for the multiple mode support system as its model of control provides a useful framework upon which different patterns of behavior observed due to varying context can be aggregated into four distinct modes.

ItemDesign of Support Systems for Dynamic Decision Making in Airline Operations(Georgia Institute of Technology, 2006-04) Feigh, Karen M. ; Pritchett, Amy R.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 has implications for both "internal" and "external" dynamic systems with respect to the human operator. Hollnagel's Contextual Control Modes are suggested as a framework for designing such support systems, noting that they can identify requirements specific to different contextual control modes.

ItemAnalyzing Air Traffic Management Systems Using Agent-based Modeling and Simulation(Georgia Institute of Technology, 2005-06) Feigh, Karen M. ; Pritchett, Amy R. ; Shah, A. P. ; Kalaver, S. A. ; Jadhav, A. ; Holl, D. M. ; Bea, R. C. ; Gilgur, A. Z.This paper presents the viewpoint that an air traffic management system is emergent, i.e., exhibiting behaviors at the system-wide level that emerge from the combined actions of individuals within the system. Emergence carries with it the additional implication that these phenomena typically cannot be predicted by examining the individuals' behavior alone. As a result, this paper proposes agent-based simulation as a method of predicting the impact of revolutionary changes to an air transportation system. Agent based simulation can integrate cognitive models of human performance, physical models of technology behavior and description of their operating environment. Simulation of these individual models acting together can predict the result of completely new transformations in procedures and technologies. While agent-based simulations cannot include every aspect of system behavior, they can provide quick, cost-effective insights that can supplement other forms of analysis.

ItemDecision Making During an Airline Rescheduling Task: A Contextual Control Model Description(Georgia Institute of Technology, 2005) Feigh, Karen M. ; Pritchett, Amy R. ; Jacko, Julie A. ; Denq, TinaThis paper examines decision makers' selection of contextual control modes as described by Hollnagel's Contextual Control Model, and evaluates real-time, unobtrusive measures of a decision maker's immediate mode. In a two-part experiment, participants performed airline rescheduling tasks. The first portion varied task time limits, the second introduced a sudden change in the task. Participants reported operating in, and transitioning between, different contextual control modes in response to time limits and task changes. Computer interaction did not correlate to contextual control modes. Contextual control modes did not correlate with TLX ratings of demand and effort, but did correlate with TLX-frustration and TLX-performance ratings. The results suggest that decision making performance may be determined by use of context-appropriate contextual control modes, and imply that the design of decision aids should work to support those modes.
