We consider the air traffic conflict resolution problem and develop an optimization model for generating speed trajectories that minimize the fuel expended to avoid conflicts. The problem is formulated by metering aircraft at potential conflict points. The developed model is a mixed integer linear program that can be solved in near real-time for large number of aircraft.
Despite the existence of several automated air traffic conflict resolution algorithms, there is a need for formulations that account for air traffic controller workload. This paper presents such an algorithm with controller workload constraints modeled parametrically. To this end, we first develop an integer programming model for general conflict resolution, which emphasizes the minimization of fuel...
Security-constrained generation scheduling (SCGS) is an indispensable tool for independent system operators (ISOs) to plan a secure and economical hourly generation schedule in the daily/weekly ahead markets. Power outputs of thermal units are usually formulated as step functions in almost all literature on SCGS, i.e., the generation level schedule is taken as an energy delivery schedule. The ramp-rate...
