Efficient solution approaches for the bi-criteria p -hub median and dispersion problem

In this paper, we study the bi-criteria p -hub median and dispersion problem, that arises in the design of hub networks where the dispersion of hubs is desired to mitigate the risk of disruptions. The problem is formulated as a bi-objective mixed integer program, where the first objective is to minimize the total cost of routing the flows through p hubs and the second objective is to maximize the minimum distance (or dispersion) among the …
