Design of a Multi objective Airlines Hub and Spoke Based Networks Using Queuing Systems Mostafa Parsa m parsa@in iut ac ir Date of Submission 2012 03 13 Department of Industrial and Systems Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language FarsiSupervisor Ali Shahandeh Ali nook@cc iut ac irAbstract Airlines utilize hub and spoke networks in order to benefit their economies of scale But according to flow centralizations some hub airports get congested especially in rush hours andnumber of delayed flies increases remarkably Common capacitated hub location models cannotprevent this adverse outcome In order to handle this problem this study considers runways ofairports as an M G 1 queuing system individually Also triple derivative models for obtainingoptimal capacity of landing takeoff and hybrid runways are proposed The final optimal capacityin the final model guarantees the average desirable delays and presence of a determined numberof planes on the runway On the other hand diversity of planes as an influential factor indesigning networks has been overlooked so far In the final proposed model besides tackling thisdeficiency we have determined procedure of allocating each kind of planes to each runway Acomputational result on the US domestic air transportation network in 2004 peak hourdemonstrates that the proposed models in this study can ensure a more balanced workload amonghubs Also former studies in the field of hub location problem have concentrated on some criteriasuch as flow costs and network construction costs There are wide gaps in this field where themain challenges of human s real live cannot be modeled Delays environmental damages such asair pollution and energy are of important challenges in air transportation industry Consideringthe abovementioned criteria we have proposed a new multi objective model based on threeeconomic environmental and energy criteria to solve the capacitated Multiple Allocation hublocation problem A computational result on the US domestic air transportation network ispresented Keywords Hub and spoke Congestion Queuing systems Environmental impact Energy Workloadbalance
