Multi-objective Hub Location Model for passenger airports with considering satisfaction passenger

This paper presents a bi-objective single allocation p-hub median problem. We explore the tradeoff between the total cost (airline companies preference) and lost time cost for passengers (customer preference). Most papers focus on airlines and the network is established based on the viewpoint of airlines despite the importance of passengers. Poor level of service for passengers, lack of convenience and satisfaction may lead to network breakdown. The most important criterion in passenger dissatisfaction in hub-spoke network are scheduling delay and trip time delay because of non-direct flight. We attempt to consider both delays in the framework of constraints and the objective function. This paper consists of two objective functions. The first objective minimizes transportation costs of airline depending on the received services (short haul, medium haul, large haul) while the second objective minimizes the cost of lost time of passengers because of using the hub-and-spoke network. For calculating this cost, the time difference between direct path as the most ideal trip condition is compared with the most ideal nonhub-hub-nonhub path and multiply it by the value of time. We performed experiments using the well-known yearbook of tourism statistics data. We found the exact pareto frontier for 34 nodes in the Iran aeronautics network.
