CAPTIVO, Maria Eugénia  and  NAMORADO CLIMACO, João. On Multicriteria Mixed Integer Linear Programming Based Tools for Location Problems-An Updated Critical Overview Illustrated with a Bicriteria DSS. Comp. y Sist. [online]. 2008, vol.12, n.2, pp.216-231. ISSN 2007-9737.

Location problems are, in general, multidimensional in nature, particularly if sustainable development planning is required. So, multicriteria approaches seem adequate in many situations. Nevertheless, only a very small percentage of the publications in this area concern multicriteria models or tools. Generally, the different criteria are formulated as constraints imposing some minimum or maximum value, or are addressed by a surrogate criterion (like distance) on a single objective structure. In this paper we outline the more relevant multicriteria mixed-integer location models and approaches taking into account several issues. The adequacy of the available models to reality is discussed. We also put in evidence the importance of interactive approaches, namely, discussing a decision support tool in which we are co-authors.
