Simulation and Optimization In Flow Planning and Management

Abstract

Most of the aviation technical community is familiar with, “What if…”, the typical question associated with simulation modeling. A simulation normally evaluates a series of proposed action plans, or scenarios, in which a computer program mimics reality by stepping through all interacting events as they happen. What happens depends of course on suggested strategies being modeled. By analyzing the aftermath, by being abl’e to have a vision of what would happen should a scheme be implemented, planners can identify sensible solutions to problems. Computer simulation, by playing out a scenario to its end, can capture nearly all the complex interactions that would take place in real life, interactions too numerous to anticipate by routine thought processes. Thus figuratively, simulation provides a crystal ball view of the future that is beyond ordinary human insight.

This chapter deals with some of the computer tools that the FAA uses to design airspace, determine policy options, test new technologies, and improve overall management of the United States airspace system. The role of modeling in planning and supporting traffic management and training functions is examined. Additional topics are dynamic techniques, databases, and other technology for determining (and revising) optimum flow plans as the airspace system changes.

To achieve system efficiency. traffic flow planning must weigh the impact of constantly changing winds, storm patterns, scheduled and unscheduled demand, and interruptions from such causes as airport closures. Applications and functions under development for the FAA Air Traffic Control System Command Center are e,xamined.
