Método de redes bayesianas para la toma de decisiones respecto a la sostenibilidad social de los proyectos de infraestructura

Acaban de publicarnos en la revista Journal of Cleaner Production un artículo donde aplicamos el método de las redes bayesianas aplicado a la toma de decisiones relacionadas con la sostenibilidad social de los proyectos. El Journal of Cleaner Production es revista de fuerte impacto, pues se encuentra en el primer decil en el ámbito ENVIRONMENTAL SCIENCES de la Web of Science.

Nowadays, sustainability assessment tends to focus on the biophysical and economic aspects of the built environment. The social aspects are generally overestimated during an infrastructure evaluation. This study proposes a method to optimize infrastructure projects by assessing their social contribution. This proposal takes into account the infrastructure’s interactions with the local environment in terms of its potential contribution in the short and long term. The method is structured in three stages: (1) preparation of a decision-making model, (2) formulation of the model, and (3) implementation of the model through optimization of infrastructure projects from the social sustainability viewpoint. The theory of Bayesian reasoning and a harmony search optimization algorithm are used to carry out the research. The paper presents the application to a case study of a set of alternatives for road infrastructure projects in El Salvador. This approach creates a model of participative decision-making. The results show that the method can distinguish socially efficient alternatives from the short and long-term contributions. In addition, the results suggest that some variables are less sensitive to the short and long-term maximization, while others vary their values to improve one objective or the other. The findings are directly applied to a real case. The method can be employed in the infrastructure formulation and prioritization phases and complemented with economic and environmental sustainability assessments.
