Following natural disasters in the United States, federal, state and local government officials must facilitate the recovery of the functionality and well-being of the affected communities. The housing sector plays a vital role in recovery because schools, businesses, neighborhoods and community-based organizations all rely on residents having healthy living conditions so that they can remain in the affected region. Existing disaster risk modeling methods are not able to adequately represent the housing recovery process and its long-term impacts to communities. This project will address this problem by developing and applying new data and computer model methods to simulate post-disaster housing recovery. The computer model will enable policy-makers and planners to quantify the benefits and tradeoffs associated with possible pre- and post-disaster housing interventions. They will be able to explore potential scenarios for various future hazard events towards the goal of enhancing housing recovery after disasters in the United States. To facilitate technology transfer to other researchers and disaster risk managers, the computer model and data from this project will be free, open source, and available over the World Wide Web. The research will provide training for a doctoral student and an opportunity to teach undergraduate students from different backgrounds about the role of science and engineering in improving the resilience of communities to natural disasters.We will investigate key questions related to housing recovery using a post-disaster recovery simulation model that integrates building performance information and homeowner decision making over space and time. The three main components of the research are (1) a probabilistic model that computes building damage using data about loss of functionality, habitability, and repairability (2) a model that quantifies the influences and uncertainty associated with homeowners' decisions whether to repair, reoccupy, sell, or abandon damaged homes based on the extent of damage, demographics, neighborhood conditions, and utility services and (3) a simulation of post-disaster housing recovery, that accounts for the influences of building, homeowner, and resource attributes, such as housing stock and population movement. We will apply the simulation model to a large urban jurisdiction for the purposes of (a) evaluation, (b) hypothesis testing, (c) and assessing potential policies and other interventions for enhancing recovery. The project will further the science in performance-based engineering and urban modeling to facilitate experiments for examining the geographic effects of post-disaster residential building functionality and housing occupancy.

在美国发生自然灾害后，联邦、州和地方政府官员必须促进受灾社区的功能恢复和福祉。住房部门在恢复中发挥着至关重要的作用，因为学校、企业、社区和社区组织都依赖于居民拥有健康的生活条件，以便他们能够留在受灾地区。现有的灾害风险建模方法无法充分代表住房恢复过程及其对社区的长期影响。该项目将通过开发和应用新的数据和计算机模型方法来模拟灾后住房恢复，从而解决这一问题。计算机模型将使决策者和规划者能够量化与灾前和灾后住房干预措施相关的利益和权衡。他们将能够探讨各种未来灾害事件的潜在情景，以实现加强美国灾后住房恢复的目标。为了促进向其他研究人员和灾害风险管理人员的技术转让，该项目的计算机模型和数据将是免费的，开源的，并可在万维网上获得。该研究将为博士生提供培训，并为来自不同背景的本科生提供机会，让他们了解科学和工程在提高社区对自然灾害的恢复力方面的作用。我们将使用灾后恢复模拟模型，将建筑物性能信息和房主决策集成在空间和时间上，研究与住房恢复相关的关键问题。该研究的三个主要组成部分是（1）一个概率模型，使用有关功能损失，可居住性和可修复性的数据计算建筑物损坏（2）一个模型，量化与业主决定是否修复，重新占用，出售或放弃受损房屋相关的影响和不确定性。和公用事业服务和（3）灾后住房恢复的模拟，该模拟考虑了建筑物、房主和资源属性（如住房存量和人口流动）的影响。我们将把模拟模型应用于一个大城市管辖区，以便（a）评估，（B）假设检验，（c）评估促进恢复的潜在政策和其他干预措施。该项目将进一步推进基于性能的工程和城市建模的科学，以促进实验，研究灾后住宅建筑功能和住房占用的地理影响。
