The aging an deterioration of highway bridges and the new requirements for sustainable infrastructures and communities require innovative approaches for their management that can achieve an adequate balance between social, economic and environmental sustainability. This paper presents a multi-objective decision-making approach for the sustainable design and management of highway bridge decks, which can considers several and conflicting objectives, such as the minimization of owner's costs, users costs, and environmental impacts and uses goal setting and compromise programming to determine the satisficing and compromise solutions that yield the best trade-off between all competing objectives. The proposed approach is based on robust reliability-based mechanistic models of the deterioration and service life of reinforced concrete bridge decks, which include diffusion models for the prediction of chloride ingress into concrete and steel corrosion and thick-walled cylinder models for the prediction of stresses induced by the accumulating corrosion products in the concrete cover. The proposed approach is illustrated on the life cycle design and management of highway bridge decks using normal and high performance concrete. It is shown that the high performance concrete deck alternative is a Pareto optimum , while the normal concrete deck is found to be a dominated solution in terms in terms of life cycle costs and environmental impacts.

Multi-Criteria Decision-Making Methods Applied to Achieve Sustainable Design: A Systematic Review

“…When considering economic and social sustainability, the results of sustainable design will fall into a trade-off of the three dimensions (Mattson, Lofthouse, Bhamra, & Asme, 2015;Mattson, Pack, Lofthouse, & Bhamra, 2019). Pareto methods can put out a set of design alternatives for the researchers and designers to further selection (Lounis & Daigle, 2013;Martinez, Gonzalez, Hospitaler, & Albero, 2019).…”

A gaming approach to networked infrastructure management

“…These normative decision support tools propose maintenance strategies over time to help the actual infrastructure managers with their decision-making (e.g. Egger, Scheidegger, Reichert, & Maurer, 2013;Liu & Frangopol, 2005;Lounis & Daigle, 2013;Marzouk & Omar, 2012;Saegrov et al, 2006;Tscheikner-Gratl, Sitzenfrei, Rauch, & Kleidorfer, 2015). The operational decision process, however, often occurs as a multi-actor planning problem, because of preferred integrated rehabilitation of adjacent infrastructures, motivated by reduction of costs and nuisance to traffic and citizens.…”
