Sensitivity analysis of airline schedule optimization (ASO) advanced model

Abstract

The ASO model provides a proposal for a new flight schedule, in situations when a carrier’s flight scheduled is disrupted, and which would minimize the negative effects of the disruption. The objective function of the model is a mathematical formulation of the company’s goals and preferences, where all assumptions and operational constraints must be satisfied. The disruption costs are given in weighted coefficients which present the penalties that can be changed by the dispatcher. One of the goals was to test to what degree the generated solutions are sensitive to changes in penalty values.
