标题： Complex network analysis of water distribution systems

摘要： 本文探讨了理解供水网络的形成、结构、效率和脆弱性的多种策略。 供水系统被研究为具有空间组织的网络，对其抽象评估方法的实际应用进行了批判性评估。 使用基准网络的经验数据来研究网络结构与运行效率、可靠性和鲁棒性之间的相互作用。 进行结构测量以量化冗余性和最优连通性等特性，这些特性在此被提出作为网络设计优化问题中的约束条件。 研究了供应需求结构对系统效率的作用，并基于节点与源断开连接来评估系统的脆弱性。 通过观察到非传统的基于度数的枢纽（通过无相关非异质稀疏拓扑观察到），促使了一种替代的方法来研究结构脆弱性，即基于网络割集和最优连通性不变量的识别。 提供了关于本研究范围、局限性和可能未来方向的讨论。 显示英文摘要

摘要： This paper explores a variety of strategies for understanding the formation, structure, efficiency and vulnerability of water distribution networks. Water supply systems are studied as spatially organized networks for which the practical applications of abstract evaluation methods are critically evaluated. Empirical data from benchmark networks are used to study the interplay between network structure and operational efficiency, reliability and robustness. Structural measurements are undertaken to quantify properties such as redundancy and optimal-connectivity, herein proposed as constraints in network design optimization problems. The role of the supply-demand structure towards system efficiency is studied and an assessment of the vulnerability to failures based on the disconnection of nodes from the source(s) is undertaken. The absence of conventional degree-based hubs (observed through uncorrelated non-heterogeneous sparse topologies) prompts an alternative approach to studying structural vulnerability based on the identification of network cut-sets and optimal connectivity invariants. A discussion on the scope, limitations and possible future directions of this research is provided.
