Abstract

ABSTRACT Infrastructure asset management is concerned with the efficient and sustainable utilization of resources. There are numerous sources of uncertainties associated with the physical state of the infrastructure, climate change, and the economy. Thus, the most appropriate decision-making process to select maintenance and replacement strategies that are sustainable, economical, and safe should also be well informed in terms of risks. The decision process is formulated as a multi-objective optimization problem and exemplified the case for targeted performance levels and total costs, and solved using both Multi-Objective Particle Swarm Optimization (MOPSO) and a Non-dominated Sorting Genetic Algorithm II (NSGA-II). The results indicate that annual budget constraints have a significant effect on the Pareto front and the schedule associated with individual solutions. The proposed approach provides a useful and flexible decision-analysis tool for managers by allowing for multiple objective optimization in scheduling future interventions towards the sustainability of infrastructure.

气候变化影响下基础设施项目可持续性的多目标优化

基础设施资产管理涉及资源的高效和可持续利用。与基础设施的物理状态、气候变化和经济有关的不确定性来源有很多。因此，选择可持续、经济和安全的维护和更换策略的最合适的决策过程也应该充分了解风险。将决策过程描述为一个多目标优化问题，并以目标性能水平和总成本为例，采用多目标粒子群优化(MOPSO)和非支配排序遗传算法II (NSGA-II)进行求解。结果表明，年度预算约束对单个方案的Pareto前沿和进度有显著影响。提出的方法为管理者提供了一个有用和灵活的决策分析工具，允许在调度未来对基础设施可持续性的干预时进行多目标优化。

期刊介绍： Sustainable and Resilient Infrastructure is an interdisciplinary journal that focuses on the sustainable development of resilient communities. Sustainability is defined in relation to the ability of infrastructure to address the needs of the present without sacrificing the ability of future generations to meet their needs. Resilience is considered in relation to both natural hazards (like earthquakes, tsunami, hurricanes, cyclones, tornado, flooding and drought) and anthropogenic hazards (like human errors and malevolent attacks.) Resilience is taken to depend both on the performance of the built and modified natural environment and on the contextual characteristics of social, economic and political institutions. Sustainability and resilience are considered both for physical and non-physical infrastructure.
