Single allocation P-Hub median problem to monitor land borders by using unmanned aircraft

Abstract

During the last two decades, hub location problems have become popular with successful applications in transportation, telecommunication, networks, retailing and other logistic systems. In this paper we consider Turkey's land borders security. Because security is the one of the most important deal nowadays, countries are spending so much to prevent threats that may come from neighbor countries' borders. Also several geographical restrictions at our land borders cause insufficiency to monitor and to take the requiring data. We focus on the problem of the single allocation p-hub median that is addressed to monitor the movement at Turkey's land borders by using unmanned aircraft. In addition, aiming assignment of demand points that are defined as cities at land borders to hubs mathematical model is built and the results are evaluated. Model is encoded by using GAMS software and solved by CPLEX solver. © Springer Science+Business Media B.V. 2010.
