Determining flight frequencies on an airline network with demand-supply interactions

Abstract

This paper determines flight frequencies on an airline network with demand-supply interactions between passenger demand and flight frequencies. The model consists of two submodels, a passenger airline flight choice model and an airline flight frequency programming model. The demand-supply interactions relevant to determining flight frequency on an airline's network are analyzed by integrating these two submodels. The necessary condition for the convergence of the demand-supply interaction is discussed. An example demonstrates the feasibility of applying the proposed models. The results are more accurate than those obtained without considering demand-supply interactions, and the models provide ways to consider demand-supply interactions well in advance to determine flight frequencies on an airline network.
