In this presentation, we address the Bounded Cardinality Hub Location Routing with Route Capacity wherein each hub acts as a transshipment node for one directed route. The number of hubs lies between a minimum and a maximum and the hub-level network is a complete subgraph. The transshipment operations take place at
the hub nodes and flow transfer time from a hub-level transporter to a spoke-level vehicle influences spoke-to-hub allocations. We propose a mathematical model and a branch-and-cut algorithm based on Benders decomposition to solve the problem. To accelerate convergence, our solution framework embeds an efficient heuristic producing high-quality solutions in short computation times. In addition, we show how symmetry
can be exploited to accelerate and improve the performance of our algorithm.
Keywords: Hub Location, Benders Decomposition.
