A Large Scale Integer Linear Programming to the Daily Fleet Assignment Problem: A Case Study in Turkey

AbstractSince poor fleet assignment can cause a great increase in costs for airline companies, a solution of the type ‘right fleet fo r the right flight’ would be very useful. In this paper, a fleet assignment model is set up using the data of the largest Airline Company in Turkey, Turkish Airlines. The aim of this model is to assign most appropriate fleet type to flights while minimizing the cost and determine optimal number of aircraft grounded overnight at each airport. The contributions of this study to Turkish Airlines will be calculated financially and the cost minimizations can be shown with the given data
