The Design of Distributed Scheduling System for Multi-Center Time-Based Metering of Air Traffic into Congested Resources

This paper describes a distributed scheduling system as created for the National Aeronautics and Space Administration’s (NASA) Multi-center Traffic Management Advisor (McTMA) prototype research system. The uses, testing, design, and operation of the proposed system are described. The system is compromised of a loosely coupled network of subschedulers that operate over short distances in order to clear conflicting merging aircraft given local points of conflict in addition to sending out constraints to other local schedulers. Delay is thereby shifted over a great deal of space and is also robust against uncertainties inherent in long-distance delay estimation for arrival times. Upon testing it was found that the proposed architecture reduced air time delays by 20-42 percent, reduced vectoring, reduced airborne holding, and gave a shorter final approach to test aircraft control centers.
