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 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.

评估不确定条件下基础设施项目的社会可持续性贡献

摘要 评估公共基础设施的可行性包括经济、技术和环境方面；然而，在许多情况下，社会方面并不总是得到充分考虑。本文提出了一种基于多标准确定性方法来估计不确定条件下基础设施项目的社会可持续性的程序。方法输入的可变性是由决策者造成的。不确定的输入通过统一和 beta PERT 分布进行处理。Monte Carlo 方法用于在方法中传播不确定性。萨尔瓦多道路基础设施改善的案例研究被用来说明这种处理方法。主要结果确定了短期和长期社会改善指数的可变性，按基础设施和替代方案优先排序的可能性。拟议的机制提高了基础设施项目早期决策的可靠性，同时考虑了它们的社会贡献。结果可以补充环境和经济可持续性评估。
