Providing reliable clean water is essential for the health and prosperity of communities. Our society, however, frequently faces the disastrous consequences of decisions made without considering their socio-economic context or the interdependency of critical infrastructure systems and services. Examples include incidents of poisonous algae in the water supply in Toledo, OH in summer 2014 and more recently, the lead contaminated water in Flint, MI which led to a declaration of a State of Emergency by the federal government. A common observation is that decisions that are primarily based on short-term cost considerations, such as those made by many municipal and city offices when facing resource constraints, can exacerbate water problems rather than improve them. This transdisciplinary research develops a water infrastructure investment decision support (WIIDS) model, calibrated with a rich repository of data. WIIDS places sustainable water services in a broad socioeconomic context that considers the inherent interdependencies of systems and interactions with the contractual, physical, and service infrastructures essential to communities.This research formulates an advanced decision model that builds on a large repository of data to support water-related decisions at different levels. Particularly, the model describes the interdependencies of water systems, road systems (that provide mobility of people and goods while applying loads on the water pipes via mechanical and environmental processes), and the contractual systems (that affect community service decisions that influence the durability of water pipes). The model consists of two distinct parts. One is an engineering sub-model that uses historical data and forecast conditions to predict the probability of failure and the associated costs for the selected sections of water supply infrastructure. Another is a socioeconomic sub-model that utilizes input from the engineering sub-model along with current and forecast business impacts, traffic impact, community demographics, and critical infrastructures (e.g., hospitals, schools) to provide holistic repair/replace/reroute recommendations. The model allows comparisons among alternative decisions (e.g. reactive vs predictive maintenance) considering social costs, indirect economic costs, and public health implications besides the direct solution costs.

提供可靠的清洁水对于社区的健康和繁荣至关重要。但是，我们的社会经常面临决定的灾难性后果，而没有考虑其社会经济背景或关键基础设施系统和服务的相互依存。例子包括俄亥俄州俄亥俄州托莱多的供水中有毒藻类事件，最近，铅在密歇根州弗林特的污染水污染了水，这导致了联邦政府宣布紧急状态的状态。一个普遍的观察结果是，主要基于短期成本考虑的决策，例如，在面对资源限制时，许多市政和城市办公室做出的决策可以加剧水问题而不是改善水性问题。这项跨学科研究开发了水基础设施投资决策支持（WIID）模型，并用丰富的数据存储库进行了校准。 WIIDS将可持续性水服务置于广泛的社会经济背景下，该环境考虑了系统的固有相互依赖性以及与社区必不可少的合同，物理和服务基础结构的互动。这项研究制定了一个先进的决策模型，该模型建立在大型数据基础上，以支持不同层次上与水相关的决策。尤其是，该模型描述了供水系统，道路系统的相互依赖性（在通过机械和环境过程在水管上施加负载的同时提供了流动性）以及合同系统（影响水管持久性的社区服务决策）。该模型由两个不同的部分组成。一种是一种工程亚型，它使用历史数据和预测条件来预测供水基础设施所选部分的失败概率和相关成本。另一个是一种社会经济的子模型，它利用工程子模型的投入以及当前和预测业务影响，交通影响，社区人口统计以及关键基础设施（例如医院，学校）提供整体维修/替代/替代/替代/重新推荐。该模型允许在替代决策（例如反应性与预测维护）之间进行比较，考虑到社会成本，间接的经济成本以及除直接解决方案成本之外的公共卫生影响。
