Bi-objective p-hub Location Problems
Abstract
In this thesis, we introduce, model, and solve bi-objective hub location problems. The
two well-known hub location problems from the literature, the p-hub median and p-hub
center problems, are uni ed under a bi-objective setting considering the single, multiple,
and r-allocation strategies. We developed a 3-index and a 4-index mixed-integer programming
formulation for each of the allocation strategies. All the formulations are tested on
the CAB dataset from the literature using a commercial optimization software. We observe
the effect of different priorities given to the objectives on the locations of hub nodes, allocations,
and the CPU time requirements with different allocation strategies under different
values of problem parameters.
