Houghton Associates, Inc. developed a comprehensive policy-based simulation for assessing the cost associated with realignment of TRACON facilities. The heart of the model is an integrated database framework that includes
Controller workforce stafﬁng and costs by facility
TRACON facility condition index
Airport facility data
Terminal Area Forecast
The TRACON simulation steps through the sequence of decision points for consolidation. Each decision point uses a pre-determined policy to decide whether a facility is consolidated into another facility or retained. The simulation also incorporates probability models for key variables such as the decision year, likely consolidation facilities, and cost uncertainties. The output of the simulation provides business case alternative cost-benefit analysis based on different policy assumptions.
