A New Approach to Single Allocation Hub Location Problem and An Application in The Air Cargo Transportation

Abstract

In this study, the new constraints which can be applied in network design problem are developed by taking especially the sectoral features of air transportation and aircraft types into consideration. A new mixed integer linear programming model is developed by including the new constraints into the traditional model of uncapacitated single allocation p-hub median problem accordingly. The aim of this study is to analyze the effects of the new constraints on the hub location. The model is tested by using Turkish air cargo statistics and the data related to the aircraft types, A300-B4 and F27-500. The results of the analysis show that the new constraints and the aircraft types used in air cargo transportation have the significant effects on the hub location problem.

Keywords

• Hub, Hub location problem, Mixed integer mathematical model, Air cargo transportation.

Tek Atamalı Ana Dağıtım Üssü Yerleşim Problemine Yeni Bir Yaklaşım ve Hava Kargo Uygulaması

Öz

Bu çalışmada özellikle hava aracı ve havayolu taşımacılığının sektörel karakteristikleri dikkate alınarak ağ tasarımı problemlerinde kullanılabilecek yeni kısıtlar geliştirilmiştir. Buna paralel olarak, yeni kısıtlar kapasite sınırı olmayan tek atamalı p-ana dağıtım üssü medyan problemi geleneksel modeline eklenmiş ve karma tamsayılı yeni bir model ortaya konmuştur. Çalışmanın amacı yeni kısıtların ana dağıtım üssü yerleşimine etkisini analiz etmektir. Geliştirilen modelin testi hava kargo taşımacılık istatistikleri ile A300-B4 ve F27-500 uçaklarına ait veriler kullanılarak gerçekleştirilmiştir. Analizler sonucunda geliştirilen yeni kısıtların ve kullanılan uçak tipinin ana dağıtım üssü yer seçimlerini önemli ölçüde etkilediği görülmüştür.
