Today, bridge design seeks not only to minimize cost, but also to minimize adverse environmental and social impacts. This multi-criteria decision-making problem is subject to variability of the opinions of stakeholders regarding the importance of criteria for sustainability. As a result, this paper proposes a method for designing and selecting optimally sustainable bridges under the uncertainty of criteria comparison. A Pareto set of solutions is obtained using a metamodel-assisted multi-objective optimization. A new decision-making technique introduces the uncertainty of the decision-maker’s preference through triangular distributions and thereby ranks the sustainable bridge designs. The method is illustrated by a case study of a three-span post-tensioned concrete box-girder bridge designed according to the embodied energy, overall safety and corrosion initiation time. In this particular case, 211 efficient solutions are reduced to two preferred solutions which have a probability of being selected of 81.6% and 18.4%. In addition, a sensitivity analysis validates the influence of the uncertainty regarding the decisionmaking. The approach proposed allows actors involved in the bridge design and decision-making to determine the best sustainable design by finding the probability of a given design being chosen.

Study of criteria used to obtain a sustainable bridge

Abstract. The sustainable development of bridges is mainly based on meeting the three pillars of sustainability (economic, social and environmental factors) which have different goals. Each main criterion groups a large number of subcritera. Therefore, achieve a sustainable bridge is a complicate problem that involves a high number of factors in each stage of bridge life-cycle. For this reason, decision-making is a helpful process to solve the sustainability problem. The objective of this work is to review the bridge life-cycle decision-making problems that involve criteria that represent the pillars of the sustainability. While some works only consider criteria related to one or two of these pillars, the most current works consider criteria that involve all the pillars of sustainability. Furthermore, most of the works reviewed only study one stage of bridge life-cycle. This study shows the criteria used in some revised journal articles in each bridge life-cycle phase and, the multi-attribute decision-making used to achieve the sustainability. In addition, a small explanation of the obtained information will be carried out.

Decisions for aging-dam management requires a transparent process to prevent the dam failure, thus to avoid severe consequences in socio-economic and environmental terms. Multiple criteria analysis arose to model complex problems like this. This paper reviews specific problems, applications and Multi-Criteria Decision Making techniques for dam management. Multi-Attribute Decision Making techniques had a major presence under the single approach, specially the Analytic Hierarchy Process, and its combination with Technique for Order of Preference by Similarity to Ideal Solution was prominent under the hybrid approach; while a high variety of complementary techniques was identified. A growing hybridization and fuzzification are the two most relevant trends observed. The integration of stakeholders within the decision making process and the inclusion of trade-offs and interactions between components within the evaluation model must receive a deeper exploration. Despite the progressive consolidation of Multi-Criteria Decision Making in dam management, further research is required to differentiate between rational and intuitive decision processes. Additionally, the need to address benefits, opportunities, costs and risks related to repair, upgrading or removal measures in aging dams suggests the Analytic Network Process, not yet explored under this approach, as an interesting path worth investigating.

Aplicación de los métodos de decisión multicriterio al diseño sostenible de puentes

Puente en cajón postesado sobre el Turia (Quart de Poblet). Proyectado por Javier Manterola y construído por Dragados y Construcciones en 1991.

Actualmente existe una tendencia clara hacia la sostenibilidad en los proyectos de estructuras, para lo cual es necesario equilibrar los criterios que apoyan esta sostenibilidad: la economía, el medio ambiente y la sociedad. Estos pilares básicos presentan objetivos diferentes y habitualmente enfrentados entre sí. Esta realidad conduce hacia la necesidad de adoptar procesos de toma de decisiones que permitan alumbrar soluciones capaces de satisfacer, de la mejor manera posible, los principios de sostenibilidad citados. Los puentes forman parte de las infraestructuras básicas de comunicación entre los distintos territorios. Por lo tanto, constituye una necesidad ineludible garantizar la sostenibilidad de este tipo de estructuras a lo largo de su ciclo de vida.

A continuación se presenta un artículo recién publicado que tiene como objetivo principal revisar la aplicación de las técnicas de decisión multicriterio al caso de los puentes. Esta investigación se enmarca dentro del proyecto BRIDLIFE (BIA2014-56574-R), en el cual participan los autores. La revisión se ha realizado atendiendo a las fases del ciclo de vida del puente, teniendo en cuenta aquellos trabajos que proponen soluciones y realizan un proceso directo de toma de decisiones respecto a estas soluciones. Asimismo, también se han considerado aquellas aportaciones que, a pesar de no realizar una selección entre varias soluciones, aplican un método de toma de decisiones para evaluar una solución en particular. La relevancia de estos trabajos estriba en la forma en que se realizan los procesos de evaluación, los cuales constituyen la piedra angular para el proyecto de un puente desde el punto de vista de la sostenibilidad, atendiendo a todas y cada una de las fases de su ciclo de vida.

Sustainability, which is founded on the reconciliation of economic, environmental, and social aspects, has become a major issue for infrastructure managers. The economic and environmental impacts of pavement maintenance are not negligible. More than $400 billion are invested globally each year in pavement construction and maintenance. These projects increase the environmental impacts of vehicle operation by 10%. Because maintenance should be technically appropriate, infrastructure managers must integrate technical, economic, and environmental aspects in the evaluation of maintenance alternatives over the life cycle of a pavement. However, these aspects are normally assessed in measurement units that are difficult to combine in the decision-making process. This research examined and compared methods for the integrated consideration of technical, economic, and environmental aspects, and this study aimed to assist highway agencies, researchers, and practitioners with the integration of these aspects for the sustainable management of pavements. For this purpose, a set of maintenance alternatives for asphalt pavements was evaluated. Methods for the integration of these aspects were explored and led to recommendations for the most suitable methods for different scenarios. As a result of this analysis, the analytic hierarchy process (AHP) is recommended when the number of alternatives is small. In these situations, the AHP leads to results that are similar to those of the weighting-sum and multiattribute approaches that are frequently used for intuitive selection. However, when the number of alternatives is large, pair comparison becomes difficult with the AHP and the weighting-sum method becomes more appropriate.
