Acaban de publicarnos un artículo en la revista Advances in Civil Engineering (revista indexada en el JCR) sobre la revisión de las técnicas de valoración multicriterio aplicadas al diseño sostenible de infraestructuras. El trabajo se enmarca dentro del proyecto de investigación DIMALIFE que dirijo como investigador principal en la Universitat Politècnica de València.
Dados los grandes impactos asociados a la construcción y mantenimiento de infraestructuras, tanto en la dimensión ambiental como en la económica y social, un enfoque sostenible de su diseño parece esencial para facilitar el cumplimiento de los Objetivos de Desarrollo Sostenible fijados por las Naciones Unidas. Un repaso a la bibliografía existente indica, por lo general, que se aplican métodos de toma de decisiones multicriterio para abordar los criterios complejos y a menudo contradictorios que caracterizan la sostenibilidad. El presente estudio revisa el estado actual de la técnica en la aplicación de dichas técnicas en la evaluación de la sostenibilidad de las infraestructuras, analizando también los impactos y criterios de sostenibilidad incluidos en las evaluaciones.

Given the great impacts associated with the construction and maintenance of infrastructures in both the environmental, the economic and the social dimensions, a sustainable approach to their design appears essential to ease the fulfilment of the Sustainable Development Goals set by the United Nations. Multicriteria decision-making methods are usually applied to address the complex and often conflicting criteria that characterise sustainability. The present study aims to review the current state of the art regarding the application of such techniques in the sustainability assessment of infrastructures, analysing as well the sustainability impacts and criteria included in the assessments. The Analytic Hierarchy Process is the most frequently used weighting technique. Simple Additive Weighting has turned out to be the most applied decision-making method to assess the weighted criteria. Although a life cycle assessment approach is recurrently used to evaluate sustainability, standardised concepts, such as cost discounting, or presentation of the assumed functional unit or system boundaries, as required by ISO 14040, are still only marginally used. Additionally, a need for further research in the inclusion of fuzziness in the handling of linguistic variables is identified.

In recent times, a great deal of interest has emerged from different sectors of society towards sustainability and sustainable product design. Decision makers are increasingly encouraged to take into consideration the economic, environmental and social dimensions of reality when dealing with problems. Sustainability is of particular importance in the field of civil engineering, where structures are designed that are long lasting and shall cause significant impacts over a long period of time, such as bridges or dams. Consequently, when addressing a structural design, civil engineers shall account for the three dimensions of sustainability, which usually show conflicting perspectives. Multi-criteria methods allow the inclusion of non-monetary aspects into the design process of infrastructure. In the postgraduate course ‘Predictive and optimisation models for concrete structures’, offered at the Masters in Concrete Engineering of the Universitat Politècnica de València, civil engineering students are taught how to apply such tools within the framework of sustainable design of concrete structures. The present paper conducts a state-of-the-art review of the main multi-criteria decision making methodologies taught in the course in the context of sustainability. Articles are searched in recognized databases, such as SCOPUS and Web of Science. The most significant methods, such as Analytical Hierarchy Process (AHP), Elimination and Choice Expressing Reality (ELECTRE), Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) or Complex Proportional Assessment (COPRAS) are systematically discussed, identifying the actual trends concerning the use of such methodologies in the field of civil engineering. The review provides a deep insight in the multi criteria techniques that are most frequently used when assessing sustainability of infrastructure designs.

Special Issue Information
In the current context of the electronic governance of society, both administrations and citizens are demanding greater participation of all the actors involved in the decision-making process relative to the governance of society. In addition, the design, planning, and operations management rely on mathematical models, the complexity of which depends on the detail of models and complexity/characteristics of the problem they represent. Unfortunately, decision-making by humans is often suboptimal in ways that can be reliably predicted. Furthermore, the process industry seeks not only to minimize cost, but also to minimize adverse environmental and social impacts. On the other hand, in order to give an appropriate response to the new challenges raised, the decision-making process can be done by applying different methods and tools, as well as using different objectives. In real-life problems, the formulation of decision-making problems and application of optimization techniques to support decisions are particularly complex and a wide range of optimization techniques and methodologies are used to minimize risks or improve quality in making concomitant decisions. In addition, a sensitivity analysis should be done to validate/analyze the influence of uncertainty regarding decision-making.

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 sólo a su coste, sino al impacto ambiental y social que generan a lo largo de su ciclo de vida.

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 case study of a road infrastructure improvement in El Salvador is used to illustrate 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 the prioritization of 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.
