新型配水管网的设计是一个重要的社会问题。运行期间的故障会引起消费节点的不足，从而降低网络的性能。WDN性能可以定义为在设计参数变化的基础上充分保证节点需求和期望压力的能力。本文的重点是考虑管道粗糙度不确定性的运行期间网络性能评估。通过蒙特卡罗模拟（MCS）生成双环WDN运行期间管道粗糙度的概率序列，对网络进行了分析。结果表明，管道粗糙度不确定性的增加会导致网络运行期间性能的下降。此外，该网络只有在前10年才具有理想的效率。因此，所提出的考虑设计变量不确定性的设计方法是评估网络性能的有效方法。
The design of new water distribution networks (WDNs) is an important social problem. Failures during an operational period provoke deficits in consumption nodes thus decreasing the performance of the network. WDN performance can be defined as the ability to sufficiently secure demand and desirable pressure in nodes based on changes in design parameters. This paper focuses on the evaluation of network performance during an operational period, taking into account pipe roughness uncertainty. A network analysis is performed by generating probabilistic series of pipe roughness using Monte Carlo simulation (MCS) in the operational period of the Two-loop WDN. Results show that an increase in pipe roughness uncertainty causes a decrease in network performance in the operational period. Furthermore, the network has a desirable efficiency only in the first 10 years. Thus, the proposed design methodology that considers the uncertainty of design variables is an effective procedure to evaluate network performance.
