对城市基础设施网络的干预不仅会对这些网络提供的服务造成干扰，还会对其他网络造成干扰，这些网络必须至少部分关闭以执行干预。由于这些影响，通过在空间上彼此接近的网络上分组干预可以获得实质性的好处。这种好处主要是由于干预成本降低和服务中断减少。本文研究了基础设施网络工作规划的两种干预分组方法。第一种是基于静态分组，第二种是基于动态分组。通过在城市地区的多个基础设施网络上制定工作计划来研究这两种方法，并与相同的方法进行比较，尽管没有协调。在本例中，对五个不同基础设施网络对象的干预根据对象的故障概率及其接近度进行分组。研究发现，动态分组方法导致工作计划，从而更好地考虑和优先考虑迫切需要干预的对象，同时考虑到由于有效协调而产生的协同效应。并对其优缺点及未来的研究方向进行了讨论。
Interventions on infrastructure networks in cities cause disruptions to the services provided by those but also to other networks that have to be at least partially shut down for the interventions executed. Due to these effects, there is substantial benefit to be obtained by grouping interventions on networks that are spatially close to one another. This benefit is principally due to reduced costs of intervention and reduced service disruption. In this paper, two intervention grouping methodologies to develop work programs for infrastructure networks are investigated. The first is based on static, the second is based on dynamic grouping. The two methodologies are investigated by developing work programs on multiple infrastructure networks in an urban area and compared against the same methodologies, albeit without coordination. In the example, interventions on the objects of five different infrastructure networks are grouped based on failure probability of the objects and their closeness. It is found that the dynamic grouping methodology results in work programs that result in a better consideration and prioritisation of objects that are in urgent need for an interventi, while accounting for the synergies that can be created due to efficient coordination. The advantages, disadvantages and future research directions are discussed.
