Nos acaban de publicar en la revista de Elsevier del primer cuartil, Environmental Impact Assessment Review, un artículo donde se valora la contribución de una infraestructura a la sostenibilidad social bajo condiciones de incertidumbre. Este artículo forma parte de nuestra línea de investigación BRIDLIFE en la que se pretenden optimizar estructuras atendiendo no solo a su coste, sino al impacto ambiental y social que generan a lo largo de su ciclo de vida.
Abstract:
Assessing the viability of a public infrastructure includes economic, technical and environmental aspects; however, on many occasions, the social aspects are not always adequately considered. This article proposes a procedure to estimate the social sustainability of infrastructure projects under conditions of uncertainty, based on a multicriteria deterministic method. The variability of the method inputs is contributed by the decision-makers. Uncertain inputs are treated through uniform and beta PERT distributions. The Monte Carlo method is used to propagate uncertainty in the method. A road infrastructure improvement case study in El Salvador illustrates this treatment. The main results determine the variability of the short and long-term social improvement indices by infrastructure and the probability of the position in prioritizing the alternatives. The proposed mechanism improves the reliability of the decision-making early in infrastructure projects, taking their social contribution into account. The results can complement environmental and economic sustainability assessments.
