Abstract:

This study provides insight into the relative predictions of models that are used to predict parameters of interest to air transportation systems. These parameters include traffic flows, delays, controller workload, and system safety. All of these models make a large number of assumptions that are inevitably buried in the computer code and are usually only known to the code developer. These invisible assumptions can have a large effect on the predicted values of important parameters. Rarely are the outputs of these models compared to actual operational data or to each other for a comparable set of inputs and for a comparable range of input variables. Models are very expensive to develop and document. In the long run, they are even more expensive to use. The training and knowledge that model/computer simulation users require is extensive. Upon extensive review of the literature (and personal familiarity with a number of the models) the authors have found that the selection of a model to conduct system sensitivity analysis should be made with great care.
