Water distribution system contamination events caused by intentional, negligent, or accidental intrusion of biological, chemical, or radioactive contaminants have significant impacts on the health of the populations that it services. Therefore, it is important to have an effective plan that can be readily implemented to minimize the impact of these contamination events. However, limited research has been focused on strategic planning of the decontamination process of the contaminated infrastructure. This paper proposed a framework for assembling a disinfection plan in real-time by (1) partitioning a WDS into a number of district metered areas (DMAs), (2) generating a solution region for each of the DMAs, and (3) assemble an effective decontamination plan using solution region generated. This framework has been applied to three contamination events. The results show that, when planning for the decontamination stage of a contamination event, the use of the proposed framework can (1) significantly reduce the response time, (2) improve the quality of the decontamination plan, and (3) provide a model for optimizing the resource allocation.
供水管网污染事件是由生物、化学或放射性污染物的故意、疏忽或意外入侵造成的，对其服务的人群的健康有重大影响。因此，拥有一个可以迅速实施的有效计划来最大限度地减少这些污染事件的影响非常重要。然而，对受污染基础设施的去污过程的战略规划的研究有限。本文提出了一个通过（1）将供水管网划分为若干分区计量区域（DMA），（2）为每个 DMA 生成解决方案区域，以及（3）使用生成的解决方案区域组装有效的去污计划来实时组装消毒计划的框架。该框架已应用于三个污染事件。结果表明，在规划污染事件的去污阶段时，使用所提出的框架可以（1）显著减少响应时间，（2）提高去污计划的质量，以及（3）为优化资源分配提供模型。
