Stream option manager

Stream option manager (SOM) is a set of mathematical tools developed at the MITRE Corporation´s Center for Advanced Aviation System Development (CAASD). While still under development, it holds the potential to provide modelers an automated capability for separation, sequencing, spacing and proper exit strategy of aircraft in en route airspace. SOM addresses all of these services in a single, integrated linear programming solution. SOM computes modified flight paths meeting all constraints while minimally deviating from preferred trajectories. A prototype implementation of SOM is being evaluated in several applications. These include (a) an automated generator of sector complexity metrics e.g., by measuring the number and magnitude of separation actions needed to resolve a given traffic situation, (b) a means of performing system-wide analyses of revised conflict resolution requirements, e.g., revised separation standards, and (c) an automated controller-surrogate for simulation studies. The SOM metrics are described, and example applications are presented.
