A branch-and-cut algorithm for the hub location and routing problem

We study the hub location and routing problem where we jointly decide on the location of hubs, the allocation of nodes to hubs, and the routing among the nodes allocated to the same hubs, with the aim of minimizing the total transportation cost. Each hub has one vehicle that visits all the nodes assigned to it on a cycle. We propose a mixed integer programming formulation for this problem and s...

A branch-and-cut algorithm for the partitioning-hub location-routing problem

We introduce the Partitioning-Hub-Location-Routing Problem (PHLRP), a hub location problem involving graph partitioning and routing features. The 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. This problem finds applications in deployment of an Internet Routing Protocol c...

A Branch-and-Cut-and-Price Algorithm for the Capacitated Location-Routing Problem

In this paper we present an exact algorithm for the Capacitated LocationRouting Problem (CLRP) based on column and cut generation. The CLRP is formulated as a set-partitioning problem which also inherits all of the known valid inequalities for the flow formulations of the CLRP. We introduce five new families of inequalities that are shown to dominate some of the cuts from the two-index formulat...

A Branch-and-cut Algorithm for the Capacitated Location-routing Problem

This paper describes a branch-and-cut algorithm for the Capacitated LocationRouting Problem (CLRP). In the CLRP customers with known demands must be served from capacitated facilities by an unlimited fleet of homogeneous, capacitated vehicles. The problem is to select a subset of potential facilities and to design vehicle routes around these facilities so that every customer is visited exactly ...
