Health & safety, and economic prosperity of the citizens of Canada are ensured with services provided by core public infrastructure. Integrity, survivability, reliability, and resiliency of drinking water supply, wastewater, and stormwater systems allow people to have a sense of security. These infrastructures are aging faster as result of impacting factors such as low funding, population growth, tighter health and environmental requirements, poor quality control leading to inferior installation, inadequate inspection and maintenance, and lack of consistency and uniformity in planning, design, construction, and operational practices. Moreover, disruptive events like flood, wildfire, earthquake are adversely impact multiple networked systems. Managing these infrastructures is not only a technical issue; rather it includes issues like finance, public acceptance, and environmental impacts. Thus, the vision of this research program is to plan sustainable and resilient buried infrastructure systems through preparedness, response, and recovery. My first objective is to develop the framework for water supply, wastewater, and stormwater systems resilience analysis. In this research, different heuristic-based techniques will be developed to integrate the matrices of resilience analysis. To consider the complex and causal relationships between different buried infrastructure systems, my second objective is to develop a multi-dimensional resilience analysis framework using different network-based approaches considering uncertainties. The third objective of this research program is to develop a multi-objective resource allocation model to understand the trade-offs among resources available and the resilience achieved through investments in vulnerability reduction and recoverability enhancements enabling planning for resilience. The last objective of this research program is to evaluate the economic effects of resource shortages over a period and the time-dependent recovery of buried infrastructures. The outcomes of this research will significantly improve the buried infrastructure management practices of Canada and support the utilities to recover from natural disasters or unwanted disruptions effectively. This unique research program will also contribute to the training of highly qualified engineers and scientists with a diverse set of skills sustainable and resilient infrastructure which will benefit Canadian private and public research. These projects will also educate and train graduate and undergraduate students in resilient systems, infrastructure management, and risk and uncertainty.

加拿大公民的健康和安全以及经济繁荣通过核心公共基础设施提供的服务得到保证。饮用水供应、废水和雨水系统的完整性、可生存性、可靠性和弹性使人们有安全感。这些基础设施老化得更快，原因是资金不足、人口增长、更严格的健康和环境要求、质量控制差导致安装质量差、检查和维护不足，以及规划、设计、施工和运营实践缺乏一致性和统一性。此外，洪水、野火、地震等破坏性事件会对多个网络系统产生不利影响。管理这些基础设施不仅是一个技术问题，还包括财务、公众接受度和环境影响等问题。因此，该研究计划的愿景是通过准备，响应和恢复来规划可持续和有弹性的地下基础设施系统。我的第一个目标是开发供水，废水和雨水系统弹性分析的框架。在这项研究中，不同的弹性为基础的技术将开发整合弹性分析矩阵。为了考虑不同的地下基础设施系统之间的复杂和因果关系，我的第二个目标是开发一个多维弹性分析框架，使用不同的基于网络的方法，考虑不确定性。该研究计划的第三个目标是开发一个多目标资源分配模型，以了解可用资源之间的权衡，以及通过投资减少脆弱性和增强恢复能力实现的恢复能力，从而实现恢复能力的规划。本研究计划的最后一个目标是评估一段时间内资源短缺的经济影响和掩埋基础设施的时间依赖性恢复。这项研究的成果将大大改善加拿大的地下基础设施管理实践，并支持公用事业公司有效地从自然灾害或不必要的中断中恢复。这一独特的研究计划还将有助于培养高素质的工程师和科学家，他们拥有多样化的技能，可持续和有弹性的基础设施，这将有利于加拿大的私人和公共研究。这些项目还将在弹性系统、基础设施管理以及风险和不确定性方面对研究生和本科生进行教育和培训。
