# Solving Partitioning-Hub Location-Routing Problem using DCA

• The Partitioning-Hub Location-Routing Problem (PHLRP) is a hub location problem involving graph partitioning and routing features. PHLRP consists of partitioning a given network into sub-networks, locating at least one hub in each sub-network and routing the traffic within the network at minimum cost. There are various important applications of PHLRP, such as in the deployment of network routing protocol problems and in the planning of freight distribution problems. We first present the formulation of this problem as an Binary Integer Linear Programming (BILP) and then investigate a new method based on DC (Difference of Convex functions) programming and DCA (DC Algorithms). Preliminary numerical results are compared with CPLEX, the best solver for BILP. These results show that the proposed algorithm is efficient.
