چکیده

In this work we address a capacitated hub problem arising from a Telecommunications application. In this problem we must choose the routes and the hubs to use in order to send a set of commodities from sources to destinations in a given capacitated network with a minimum cost. The capacities and costs of the arcs and hubs are given, and the graph connecting the hubs is not assumed to be complete. We present a mixed integer linear programming formulation and describe three different decomposition techniques to get better performances than simply using a direct general solver on the model. These approaches can be applied to deal with more general problems in Network Design.

Scenario-based modeling for multiple allocation hub location problem under disruption risk: multiple cuts Benders decomposition approach

The hub location problem arises in a variety of domains such as transportation and telecommunication systems. In many real-world situations, hub facilities are subject to disruption. This paper deals with the multiple allocation hub location problem in the presence of facilities failure. To model the problem, a two-stage stochastic formulation is developed. In the proposed model, the number of ...

Capacitated Single Allocation P-Hub Covering Problem in Multi-modal Network Using Tabu Search

The goals of hub location problems are finding the location of hub facilities and determining the allocation of non-hub nodes to these located hubs. In this work, we discuss the multi-modal single allocation capacitated p-hub covering problem over fully interconnected hub networks. Therefore, we provide a formulation to this end. The purpose of our model is to find the location of hubs and the ...

Design of a Bi-Objective Capacitated Single-Allocation Incomplete Hub Network Considering an Elastic Demand

This paper presents a bi-objective capacitated hub arc location problem with single assignment for designing a metro network with an elastic demand. In the literature, it is widely supposed that the network created with the hub nodes is complete. In this paper, this assumption is relaxed. Moreover, in most hub location problems, the demand is assumed to be static and independent of the location...
