Multicriteria Analysis in Telecommunication Network Planning and Design — Problems and Issues

A review of interactive methods for multiobjective integer and mixed-integer programming

“…Recently, an increasing number of scientific papers has appeared in the literature (see Clímaco and Craveirinha, 2004). We emphasize those related to QoS (quality of service) routing problems.…”

A Hierarchical Multiobjective Routing Model for MPLS Networks with Two Service Classes

“…When one states that using the minimization of path implied cost 'tends' to maximize W T this would be in rigor only valid if the choice of such an 'optimal' path for a given f s would not change in any form the network working condition, an assumption that is not true, having in mind the interdependencies among {c ks }, {B ks } and R (see (4)). This is the ultimate source of difficulty in devising a heuristic based on this principle, as outlined in the next section.…”

“…In contrast, flow-oriented optimization models consider the objective functions formulated at the level of each particular node-to-node connection or flow, for example number of arcs of the path, path cost (for a specific link usage path metric) or mean packet delay on the particular traffic stream. Examples of this type of models are the numerous QoS routing models which are based on single-objective constrained shortest path formulations (a review can be seen in [22] and an overview in [4]). Another feature refers to the nature of the chosen objective functions and constraints, namely whether the optimization model is single or multiobjective, and the type of functions and constraints (technical, economic, social or other).…”

“…An overview of some applications of MCDA (Multicriteria Decision Analysis) tools in telecommunication strategic planning and negotiation is shown in [16]. A review on applications of MCDA in telecommunications network planning and design, including a section on routing models, is presented in [4]. An overview of a significant number of contributions on multicriteria routing models in telecommunication networks followed by a description of a bi-level hierarchical multicriteria routing model of the flow-oriented optimization type, is put forward in [5].…”

Hierarchical multiobjective routing model in Multiprotocol Label Switching networks with two service classes – a Pareto archive strategy

“…QoS issues have become increasingly relevant in the new technological platforms of multiservice networks, triggering an interest in the application of multicriteria approaches to routing models in communication networks (see Wierzbicki and Burakowski (2011), Wierzbicki (2005) and reviews in Clímaco and Craveirinha (2005), Clímaco et al (2007), where some recent research papers on multiobjective routing models in multiservice networks are cited). In particular, a significant number of multicriteria routing models has been proposed in the context of the emergent MPLS (Multiprotocol Label Switching) Internet networks (see Clímaco et al (2007)), motivated by its advanced routing capabilities, see Awduche et al (2002), namely the possibility of implementing QoS routing methods, see Kuipers et al (2002).…”
