Future generations of air traffic management systems will give appropriately equipped aircraft the freedom to change flight paths in real-time. This will require a conflict avoidance and resolution scheme that is both decentralized and cooperative. Satisficing game theory provides a theoretical framework in which autonomous decision makers may coordinate(More)
This brief contribution introduces a method of quantifying the locality in a given reference sequence and visually representing it as a three dimensional surface. We explore some of the properties of this formulation of locality and show the correlation between graphical features and specific reference patterns. The utility of our formulation of locality is(More)
The next generation of air traffic control will require automated decision support systems in order to meet safety, reliability, flexibility, and robustness demands in an environment of steadily increasing air traffic density. Automation is most readily implemented in <i>free flight</i>, the segment of flight between airports. In this environment,(More)
The next generation of air traffic control will require automation in order to meet safety, reliability, flexibility, and robustness demands in an environment of steadily increasing air traffic density. Optimization, however, is an inadequate paradigm for the design of a cooperative distributed air traffic control system. The problem stems from a(More)
Model-predictive control, which is an alternative to conventional optimal control, provides controller solutions to many constrained and nonlinear control problems. However, even when a good model is available, it may be necessary for an expert to specify the relationship between local model predictions and global system performance. We present a(More)
