Abstract

ABSTRACT Critical infrastructure systems are essential in sustaining people’s livelihoods and the operation of economic sectors. In this paper, we extend the dynamic inoperability IO model (DIIM), we evaluate the resilience of economic sectors given the initial functionality loss and recovery time of an infrastructure. The resulting model is applied in a case study of the 2020 eruption of Taal Volcano in the Philippines. The initial inoperability and recovery period parameters are used in the 14-sector DIIM. The dynamic recovery behaviors of the sectors are plotted over the disaster timeline based on two metrics: (1) economic loss, which is the monetary value of the damage; and (2) inoperability, which is the dimensionless loss relative to the total production output of each sector. The DIIM template and case study results from this paper can provide policy insights to enhance disaster resilience planning for future disasters.

使用动态不可操作性投入产出模型评估关键基础设施故障的经济连锁反应：以塔尔火山爆发为例

摘要关键的基础设施系统对于维持人们的生计和经济部门的运作至关重要。在本文中，我们扩展了动态不可操作性IO模型（DIIM），在给定基础设施的初始功能损失和恢复时间的情况下，我们评估了经济部门的弹性。由此产生的模型被应用于2020年菲律宾塔尔火山爆发的案例研究。在14扇区DIIM中使用初始不可操作性和恢复周期参数。基于两个指标绘制了各部门在灾害时间线上的动态恢复行为：（1）经济损失，即损失的货币价值；以及（2）不可操作性，这是相对于每个部门的总生产产出的无量纲损失。本文的DIIM模板和案例研究结果可以为加强未来灾害的抗灾能力规划提供政策见解。

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.
