DESIGN OF A COOPERATIVE PROBLEM-SOLVING SYSTEM FOR EN-ROUTE FLIGHT PLANNING: AN EMPIRICAL EVALUATION
Both optimization techniques and expert systems technologies are popular approaches for developing tools to assist in complex problem-solving tasks. This study evaluates the impact of alternative design concepts on the performance of 30 airline pilots interacting with a cooperative system designed to support en-route flight planning. The results clearly demonstrate that different system design concepts can strongly influence the cognitive processes and resultant performances of users. Based on think-aloud protocols, cognitive models are proposed to account for how features of the computer system interacted with specific types of scenarios to influence exploration and decision making by the pilots. The results are then used to develop recommendations for guiding the design of cooperative systems.
