| Abstract: | When events such as severe weather or congestion interfere with the normal flow of air traffic, air traffic controllers may implement "plays" that reroute one or more traffic flows. Currently, plays are assessed and selected based on controllers’ experience using the National Playbook, a collection of plays that have worked in the past. This paper introduces PlayMaker, a prototype using case-based reasoning (CBR) that replicates the Playbook and models how controllers select plays. CBR is an artificial intelligence method in which the system compares stored previous experiences, known as cases, to novel situations. To the extent that a stored case matches the novel situation, the solution used during the previous experience can be applied to the current situation. The CBR technique very closely matches the technique already used by controllers in selecting plays. This paper describes the PlayMaker design and presents a validation of the model in which its responses were compared to those of a human expert. In most situations, PlayMaker was able to make recommendations that would be deemed reasonable from a controller’s perspective. In two situations, however, PlayMaker could not make a recommendation due to the complexity of the air traffic situation and the limitations of the prototype. The paper discusses improvements necessary for a full-scale CBR tool for this application, including ways to resolve these more difficult situations. |
