Water is a critical resource and a lifeline service to communities worldwide; the generation, treatment, distribution and maintenance of water workflows is typically managed by local governments and water districts. Recent events such as water supply disruptions caused by Hurricane Sandy in 2012 and the looming California drought crisis clearly indicate society's dependence on critical lifeline services such as water and the far-reaching impacts that its disruption can cause. Over the years, these critical infrastructures have become more complex and often more vulnerable to failures. The ability to view water workflows as a community wide cyber-physical system (CPS) with multiple levels of observation/control and diverse players (suppliers, distributors, consumers) presents new possibilities. Designing robust water systems involves a clear understanding of the structure, components and operation of this CPS system and how community infrastructure dynamics (e.g. varying demands, small/large disruptions) impact lifeline service availabilities and how service level decisions impact infrastructure control. The proposal emphasizes a new approach to exploring engineering systems that will result in substantial advances in the understanding of lifeline systems and approaches to make them adaptive and resilient. Building resilience into urban lifelines raises a number of monumental challenges including identifying the aspects of systems that can be observed/sensed and adapted and to developing general principles that can guide adaptation. The key idea is to develop methodologies to understand operational performance and resilience issues for real-world community water infrastructures and explore solutions to problems in cyberspace before instantiating them into a physical infrastructure. The effort includes: 1) Developing a flexible modeling framework that captures system needs at multiple levels of temporal and spatial abstraction; 2) Developing real-time algorithms supporting resilience; 3) Designing adaptations for water systems using a data-driven approach; and 4) Demonstrating the important broader impact of the research on critical water system infrastructure at the Global City Technology Challenge and the longer term impact on infrastructure for a resilient control framework.

水是全世界社区的关键资源和生命线服务。水工作流的一代，治疗，分配和维护通常由地方政府和水域管理。 最近的事件，例如2012年由飓风桑迪（Sandy）造成的供水中断和加利福尼亚干旱危机，这清楚地表明，社会对关键生命线服务（例如水以及其破坏可能造成的深远影响）的依赖。 多年来，这些关键基础设施变得更加复杂，并且通常更容易受到失败的影响。将水工作流视为社区广泛的网络物理系统（CPS）的能力，具有多个级别的观察/控制和不同的参与者（供应商，分销商，消费者）提出了新的可能性。 设计强大的供水系统涉及对该CPS系统的结构，组件和操作的清晰了解，以及社区基础设施动态如何（例如不同的需求，小/大的中断）影响生命线服务的可用性以及服务水平的决策如何影响基础架构控制。该提案强调了一种探索工程系统的新方法，该方法将在理解生命线系统和方法方面取得重大进展，以使其自适应和韧性。 在城市寿命中建立韧性提出了许多巨大的挑战，包括确定可以观察/感知和适应系统的系统方面，并制定可以指导适应的一般原则。 关键思想是开发方法，以了解现实世界社区水基础设施的运营绩效和弹性问题，并在将它们实例化成物理基础设施之前探索网络空间中问题的解决方案。 努力包括：1）开发一个灵活的建模框架，该框架在时间和空间抽象的多个级别捕获系统需求； 2）开发支持弹性的实时算法； 3）使用数据驱动的方法为供水系统设计适应； 4）在全球城市技术挑战中展示了研究对关键水系统基础设施的重要广泛影响，以及对弹性控制框架的基础设施的长期影响。
